AB  - Organic pollutants in sediments are a worldwide problem because sediments act as sinks for hydrophobic, toxic, persistent and bioaccumulative hazardous compoundssuch as pentachlorobenzene (PeCB). PeCB can be involved in adsorption, desorption and transformation processes and can be made available to benthic organisms through the sediment-water interface. In order to reduce the risk, this study investigates effects of the dose and contact time between sediment and carbon-rich amendments (activated carbon (AC), biochar (BC) and hummus (HC)) on the effectiveness of detoxification. Four doses of carbon-rich amendments (0.5-10 %) and four equilibrations contact times (14 -180 days) were investigated. The present research highlights the need for further examination and process optimization of different carbon-rich materials used for contaminant removal. Results have shown that the smallest dose (0.5 %) of investigated sorbents was sufficient to reduce the bioavailable fraction of PeCB below 5 %, and the ageing process after 14 days for AC and 30 days for HM and BC negligibly influenced the bioavailable fraction.

AB  - Background: The increased use of pesticides leads to permanent pollution of soil, and there is a need for continuous monitoring of these agrochemicals in soil. Objective: Three methods for the simultaneous determination of 12 pesticides belonging to eight chemical groups in soil samples were tested and compared based on analytical parameters. Methods: The quick, easy, cheap, effective, rugged, and safe (QuEChERS); traditional solid-liquid extraction (SLE); and Soxhlet extraction were used for soil sample preparation, while detection and quantification of pesticides were performed using gas chromatography-mass spectrometry (GC-MS). Results: The tested methods featured good sensitivity, and with the exception for carbofuran (Soxhlet method, LOD = 29 mu g/kg), for the rest of the pesticides, the studied LODs were less than 12 mu g/kg. Except for simazine and carbofuran, LODs obtained by Soxhlet extraction were lower than values obtained by other two methods, whereas QuEChERS gave lower LODs than the traditional SLE method for all compounds except atrazine and acetochlor. The recoveries obtained applying QuEChERS, traditional SLE, and Soxhlet methods for multiple analyses of soil samples fortified at 10,75, and 200 mu g/kg of each pesticide were in the ranges 54-103,40-91, and 12-92%, respectively. Except for chlorothalonil, the highest recoveries were obtained by the QuEChERS method. Soxhlet was better than traditional SLE method for chlorothalonil, heptachlor, and aldrin; organophosphorus pesticides (fenitrothion and diazinon) and trifluralin, gave similar recoveries for both methods. All three methods were proven to be repeatable, with RSDs lower than 19%. Conclusions: Although all tested methods showed as satisfactory regarding most analytical parameters, QuEChERS method showed much better results in terms of confidence, indicating that traditional SLE and Soxhlet extraction still need improvements for determination of multiclass pesticides in soil samples.

AB  - The chemical and biological trait approach have been applied to sediment pollution assessment of the Veliki Bgki canal (Serbia)-VBC. For this assessment, pseudo-total metal contents, pollution load index (PLI), contamination factor (CF), enrichment factor (EF), sequential extraction procedure (SEP), pore water metal concentrations, geoaccumulation factor (I-geo), sediment quality guidelines (SQGs) and risk assessment code (RAC) have been used. Furthermore, the phytotoxic effects of the contaminated sediment have been assessed according to the physiological and morphological trait changes of the test plant species (maize, white mustard, barley and cucumber) in a bioassay. The chemical analysis has shown that an assessed sediment from VBC is extremely polluted with Cd, Zn, Ni whereas pore water is polluted with Cu, Zn, Ni. The results which have been acquired in plant bioassays indicate the different sensitivity of the plants. While pore water from the contaminated sediment had no effect on maize traits, it considerably inhibited the physiological and morphological traits of barley, cucumber and white mustard. These species are potentially good indicators of impaired sediment quality.

AB  - Zagađenje vode i sedimenta, organskim jedinjenjima, teškim metalima i agrohemikalijama, poslednjih decenija predstavlja problem koji je prisutan u svim regionima sveta. Kako bi se umanjile negativne posledice primene zagađene vode i sedimenta u poljoprivredi, neophodan je kontinuirani monitoring njihovog kvaliteta, odreĎivanje prisustva i kvantifikacija polutanata i procena njihove biodostupnosti. Kvalitet vode i sedimenta može se oceniti pomoću fizičko-hemijskih i bioloških metoda (bioindikatora). Poslednja grupa je od značaja u detekciji zagaĎenja i proceni kvaliteta vode i sedimenta koji se koriste u poljoprivredi. Otuda gajene biljke kao bioindikatori imaju važnu ulogu. Rezultati ovakvih ispitivanja su direktan pokazatelj mogućnosti upotrebe vode za navodnjavanje, a sedimenta za razastiranje po obradivim površinama. Imajući u vidu izneto, u radu je preko fizioloških (energija klijanja i klijavost semena) i morfoloških (dužina, sveža i suva masa korena i nadzemngo dela ponika) promena na deset vrsta gajenih biljaka (kukuruz, ječam, krmni sirak, bela slačica, kupus, rotkvica, krastavac, pasulj, suncokreta i heljda), procenjen biološki potencijal istih u detekciji zagaĎenja vode i sedimenta teškim metalima, pesticidima i drugim polutantima. Kvalitet vode i sedimenta, odnosno detekcija zagaĎenja, odreĎeni su prvo hemijskim analizama, a zatim pomoću bioloških testova, tokom 2011-2015. godine. Ukupno je analizirano 37 uzoraka vode i osam uzoraka sedimenta sa teritorije AP Vojvodine (Srbija), od kojih su 29 iz kanala (Veliki Bački kanal /VBK/, Aleksandrovački kanal /AK/, Nadela, Feketić i Čelarevo), pet iz reka (Krivaja, Begej i Dunav) i tri iz zatvorenih vodenih površina koje se nalaze u okviru rezervata prirode i zaštićenih prirodnih dobara (Jegrička, Stari Begej /“Carska bara”/ i Stara Tisa). U radu su primenjene metode naklijavanja semena na filter hartiji propisane Pravilnikom o kvalitetu semena poljoprivrednog bilja (Sl. list 34/2013) i pravilnikom ISTA (2011). Tokom 2013. godine, praćene su i sezonske promene u sadržaju metala: nutrijenti (Na, Mg, Ca i K) i prioritetni polutanti u vodi (Cd, Ni, Pb, Cr, As) prema Direktivi 2008/105EC, teški metali (Fe, Mn, Zn, Cu), zatim pesticidi (herbicidi iz grupe triazina i urea) u kanalu u Čelarevu i VBK III. U radu je ispitan uticaj najznačajnijih polutanata u vodi (teški metali: Cd, Cu, Ni, Pb, Cr i insekticid hlorpirifos) prema Direktivi 2008/105EC, Uredbi 50/12 i ICPDR klasifikaciji (2004). Za obradu podataka korišćeni su statistički softveri SPSS 19 i ARO 3.2, a primenjene su ANOVA (Dankanov test višestrukih poreĎenja, Kruskal-Valisov test i t test) i višestruka regresiono-korelaciona analiza. Hemijske analize ukazuju na organsko i neorgansko zagaĎenje vode iz VBK (I, II, III) AK, Krivaje, Nadele, Begeja, Dunava kod izliva komunalnih voda i kanala u Čelarevu. ZagaĎenje teškim metalima je registrovano u vodi iz VBK I (Cd), AK (Cr), VBK II (Cr), kanala u Feketiću (As) i u pojedinim mesecima u kanalu u Čelarevu (Cr i Mn i Fe) i VBK III (Cr, Mn, Fe, Pb i As). Pojedini uzorci sedimenta su zagaĎeni teškim metalima i PAH-ovima i to: VBK I sa Cu (II klasa) i PAH-ovima (III klasa); AK sa Ni i Cu (III klasa) i Cr (IV klasa); VBK II sa Cu i PAH-ovi (II klasa); Krivaja sa Ni i Cu (II klasa); Nadela sa Ni (III klasa) i Cd (IV klasa); Begej sa Ni (III klasa). Uticaj kvaliteta vode i sedimenta na test biljke je varirao u zavisnosti od sadržaja polutanata, nutrijenata, ali i od biljne vrste i ispitivanog parametra. Dobri indikatori narušenog kvaliteta, odnosno zagaĎenja vode i sedimenta su: bela slačica, kupus, rotkvica i heljda, jer su na prisustvo jedinjenja i elemenata u količinama preko maksimalno dozvoljenik (MDK), reagovali inhibicijom većine parametara. Kukuruz, ječam, krmni sirak, pasulj i suncokret ispoljili su slabiji potencijal kao indikatori, s obzirom na mali broj parametara koji su pod uticajem kvaliteta vode i sedimenta. Fiziološki parametri (energija klijanja i klijavost) se nisu pokazali kao pouzdani u detekciji narušenog kvaliteta vode i sedimenta, osim u slučaju bele slačice, kupusa, rotkvice i heljde za zagaĎenja sa N, NH3, P i Cr. Morfološke promene na test biljkama su bolji pokazatelji zagaĎenja Cr, Pb, Mn, N, NO3, NH3 i P. U okviru sezonskog monitoringa, potvrĎena je promena sadržaja nutrijenata, teških metala i pesticida, zavisno od meseca uzorkovanja, a koji su u vezi sa intenzivnim poljoprivrednim aktivnostima. Najveće količine herbicida iz grupe triazina i urea, preko MDK, detektovane su tokom proleća i leta, što se dovodi u vezu za poljoprivrednom praksom suzbijanja korova. U biotestu, voda uzorkovana tokom proleća i leta, ispoljila je izrazit negativan uticaj uglavnom na morfološke parametre test biljaka u vidu inhibicije porasta korena i nadzemnog dela, dok energija klijanja i klijavost kod većine vrsta uglavnom nisu pod uticajem prisustva herbicida. Test biljke su ispoljile različit potencijal kao indikatori u detekciji zagaĎenja vode pojedinačnim polutantima. Kukuruz je preko sledećih parametara dobar pokazatelj prisustva polutanata u MDK (0,1 μg/l): energija klijanja i klijavost su dobri pokazatelji zagaĎenja Cr i Zn, a energija klijanja samo Pb, dužina korena za Zn i hlorpirifos, sveža masa korena za Zn, Pb i hlorpirifos, suva masa korena za hlorpirifos, dužina nadzemnog dela za Zn i hlorpirifos, sveža masa nadzemnog dela za Zn, Ni i hlorpirifos, a suva masa nadzemnog dela samo za hlorprifos. Ječam je dobar indikator prisustva sledećih polutanata u MDK preko dužine korena za Cd, dužine nadzemnog dela za Ni, a sveže i suve mase istog za Zn, dok svi fiziološki i morfoloških pamaretri ukazuju na zagaĎenje hlorpirifosom. Krmni sirak je dobar indikator prisustva Zn u količinama preko MDK preko energije klijanja i klijavosti, preko dužine, sveže i suve mase korena i dužine nadzemnog dela za Pb, a preko dužine i sveže mase nadzemnog dela za Cd. Bela slačica je preko energije klijanja, klijavosti i svih parametara korena dobar indikator prisustva Zn u MDK, preko dužine sveže i suve mase korena i mase nadzemnog dela za Ni, preko sveže mase nadzemnog dela za Cd, dok su svi fiziološki i morfološki parametri dobri indikatori zagaĎenja vode hlorpirifosom. Kupus je dobar indikator prisustva Cd u vodi u MDK preko sveže mase korena i svih parametara nadzemnog dela ponika. Rotkvica je dobar pokazatelj prisustva različitih polutanata u MDK: energija klijanja za Zn, sveža masa korena za Cd, Pb, Zn, suva masa korena Cd i Pb, a svi parametri nadzemnog dela za Cd, Zn i Pb. Krastavac je dobar pokazatelj prisustva različitih polutanata u MDK količinama preko sledećih parametara: dužine korena za Ni, Pb i hlorpirifos, sveže mase za Ni, Zn, Pb i hlorpirifos, suve mase za Cd, Ni, Zn i hlorpirifos, dužine nadzemnog dela za Cu, Zn, Pb i hlorpirifos, sveže mase istog za Cd i Pb i hloripirifos, a suve masa samo za hlorpirifos. Pasulj je dobar indikator prisustva različitih polutanata u MDK, preko sledećih parametara: energija klijanja i klijavost za Zn, dužina korena za Cd, Zn i Pb, sveža masa korena za Zn, suva masa korena za Cd, Pb i Zn, sveža i suva masa nadzemnog dela za Cd. Suncokret je dobar pokazatelj prisustva različitih polutanata u MDK i to preko dužine i sveže mase korena za Cd, Cu i Pb, suve mase korena za Cd i Cu, a dužine nadzemnog dela za Zn i Pb. Heljda je dobar pokazatelj prisustva Zn u MDK preko energije klijanja, klijavosti, preko dužine, sveže i suve mase korena ponika i sveže i suve mase nadzemnog dela za Cd, a preko sveže i suve mase korena za Pb. Na osnovu ostvarenih rezultata hemijskih analiza i biotesta, voda iz Dunava, sa plaže Bećarac i iz Sr. Karlovaca, može se koristiti za navodnjavanje. MeĎutim, preporuka je da se vode iz VBK I, II, III, AK, Krvaje, Nadele, Begeja, Dunava kod izliva konunalnih voda, Starog Begeja („Carska bara“), kanala u Fektiću, Stare Tise i kanala u Čelarevu, isključe iz poljoprivredne proizvodnje, zbog mogućih fitotoksičnih efekata. TakoĎe, i svi uzorci sedimenta su ispoljili fitotksične efekte na test biljke, te se ne preporučuje njhovo odlaganje po poljoptivrednim površinama, bez predhodne procene rizika.

Tokom 2013. godine, praćene su i sezonske promene u sadržaju metala: nutrijenti (Na, Mg, Ca i K) i prioritetni polutanti u vodi (Cd, Ni, Pb, Cr, As) prema Direktivi 2008/105EC, teški metali (Fe, Mn, Zn, Cu), zatim pesticidi (herbicidi iz grupe triazina i urea) u kanalu u Čelarevu i VBK III. U radu je ispitan uticaj najznačajnijih polutanata u vodi (teški metali: Cd, Cu, Ni, Pb, Cr i insekticid hlorpirifos) prema Direktivi 2008/105EC, Uredbi 50/12 i ICPDR klasifikaciji (2004). Za obradu podataka korišćeni su statistički softveri SPSS 19 i ARO 3.2, a primenjene su ANOVA (Dankanov test višestrukih poreĎenja, Kruskal-Valisov test i t test) i višestruka regresiono-korelaciona analiza. Hemijske analize ukazuju na organsko i neorgansko zagaĎenje vode iz VBK (I, II, III) AK, Krivaje, Nadele, Begeja, Dunava kod izliva komunalnih voda i kanala u Čelarevu. ZagaĎenje teškim metalima je registrovano u vodi iz VBK I (Cd), AK (Cr), VBK II (Cr), kanala u Feketiću (As) i u pojedinim mesecima u kanalu u Čelarevu (Cr i Mn i Fe) i VBK III (Cr, Mn, Fe, Pb i As). Pojedini uzorci sedimenta su zagaĎeni teškim metalima i PAH-ovima i to: VBK I sa Cu (II klasa) i PAH-ovima (III klasa); AK sa Ni i Cu (III klasa) i Cr (IV klasa); VBK II sa Cu i PAH-ovi (II klasa); Krivaja sa Ni i Cu (II klasa); Nadela sa Ni (III klasa) i Cd (IV klasa); Begej sa Ni (III klasa). Uticaj kvaliteta vode i sedimenta na test biljke je varirao u zavisnosti od sadržaja polutanata, nutrijenata, ali i od biljne vrste i ispitivanog parametra. Dobri indikatori narušenog kvaliteta, odnosno zagaĎenja vode i sedimenta su: bela slačica, kupus, rotkvica i heljda, jer su na prisustvo jedinjenja i elemenata u količinama preko maksimalno dozvoljenik (MDK), reagovali inhibicijom većine parametara. Kukuruz, ječam, krmni sirak, pasulj i suncokret ispoljili su slabiji potencijal kao indikatori, s obzirom na mali broj parametara koji su pod uticajem kvaliteta vode i sedimenta. Fiziološki parametri (energija klijanja i klijavost) se nisu pokazali kao pouzdani u detekciji narušenog kvaliteta vode i sedimenta, osim u slučaju bele slačice, kupusa, rotkvice i heljde za zagaĎenja sa N, NH3, P i Cr. Morfološke promene na test biljkama su bolji pokazatelji zagaĎenja Cr, Pb, Mn, N, NO3, NH3 i P. U okviru sezonskog monitoringa, potvrĎena je promena sadržaja nutrijenata, teških metala i pesticida, zavisno od meseca uzorkovanja, a koji su u vezi sa intenzivnim poljoprivrednim aktivnostima. Najveće količine herbicida iz grupe triazina i urea, preko MDK, detektovane su tokom proleća i leta, što se dovodi u vezu za poljoprivrednom praksom suzbijanja korova. U biotestu, voda uzorkovana tokom proleća i leta, ispoljila je izrazit negativan uticaj uglavnom na morfološke parametre test biljaka u vidu inhibicije porasta korena i nadzemnog dela, dok energija klijanja i klijavost kod većine vrsta uglavnom nisu pod uticajem prisustva herbicida. Test biljke su ispoljile različit potencijal kao indikatori u detekciji zagaĎenja vode pojedinačnim polutantima. Kukuruz je preko sledećih parametara dobar pokazatelj prisustva polutanata u MDK (0,1 μg/l): energija klijanja i klijavost su dobri pokazatelji zagaĎenja Cr i Zn, a energija klijanja samo Pb, dužina korena za Zn i hlorpirifos, sveža masa korena za Zn, Pb i hlorpirifos, suva masa korena za hlorpirifos, dužina nadzemnog dela za Zn i hlorpirifos, sveža masa nadzemnog dela za Zn, Ni i hlorpirifos, a suva masa nadzemnog dela samo za hlorprifos. Ječam je dobar indikator prisustva sledećih polutanata u MDK preko dužine korena za Cd, dužine nadzemnog dela za Ni, a sveže i suve mase istog za Zn, dok svi fiziološki i morfoloških pamaretri ukazuju na zagaĎenje hlorpirifosom. Krmni sirak je dobar indikator prisustva Zn u količinama preko MDK preko energije klijanja i klijavosti, preko dužine, sveže i suve mase korena i dužine nadzemnog dela za Pb, a preko dužine i sveže mase nadzemnog dela za Cd. Bela slačica je preko energije klijanja, klijavosti i svih parametara korena dobar indikator prisustva Zn u MDK, preko dužine sveže i suve mase korena i mase nadzemnog dela za Ni, preko sveže mase nadzemnog dela za Cd, dok su svi fiziološki i morfološki parametri dobri indikatori zagaĎenja vode hlorpirifosom. Kupus je dobar indikator prisustva Cd u vodi u MDK preko sveže mase korena i svih parametara nadzemnog dela ponika. Rotkvica je dobar pokazatelj prisustva različitih polutanata u MDK: energija klijanja za Zn, sveža masa korena za Cd, Pb, Zn, suva masa korena Cd i Pb, a svi parametri nadzemnog dela za Cd, Zn i Pb. Krastavac je dobar pokazatelj prisustva različitih polutanata u MDK količinama preko sledećih parametara: dužine korena za Ni, Pb i hlorpirifos, sveže mase za Ni, Zn, Pb i hlorpirifos, suve mase za Cd, Ni, Zn i hlorpirifos, dužine nadzemnog dela za Cu, Zn, Pb i hlorpirifos, sveže mase istog za Cd i Pb i hloripirifos, a suve masa samo za hlorpirifos. Pasulj je dobar indikator prisustva različitih polutanata u MDK, preko sledećih parametara: energija klijanja i klijavost za Zn, dužina korena za Cd, Zn i Pb, sveža masa korena za Zn, suva masa korena za Cd, Pb i Zn, sveža i suva masa nadzemnog dela za Cd. Suncokret je dobar pokazatelj prisustva različitih polutanata u MDK i to preko dužine i sveže mase korena za Cd, Cu i Pb, suve mase korena za Cd i Cu, a dužine nadzemnog dela za Zn i Pb. Heljda je dobar pokazatelj prisustva Zn u MDK preko energije klijanja, klijavosti, preko dužine, sveže i suve mase korena ponika i sveže i suve mase nadzemnog dela za Cd, a preko sveže i suve mase korena za Pb. Na osnovu ostvarenih rezultata hemijskih analiza i biotesta, voda iz Dunava, sa plaže Bećarac i iz Sr. Karlovaca, može se koristiti za navodnjavanje. MeĎutim, preporuka je da se vode iz VBK I, II, III, AK, Krvaje, Nadele, Begeja, Dunava kod izliva konunalnih voda, Starog Begeja („Carska bara“), kanala u Fektiću, Stare Tise i kanala u Čelarevu, isključe iz poljoprivredne proizvodnje, zbog mogućih fitotoksičnih efekata. TakoĎe, i svi uzorci sedimenta su ispoljili fitotksične efekte na test biljke, te se ne preporučuje njhovo odlaganje po poljoptivrednim površinama, bez predhodne procene rizika.",

AB  - Irrigation is one of the most important uses of surface waters in the agricultural region of Vojvodina province (Serbia). The aim of the study was to assess the quality of water from Stara Tisa meander, based on the levels of pollution with metals, volatile compounds (VOC), pharmaceuticals, pesticides, and pathogenic bacteria, on sunflower, cabbage, cucumber, maize, barley, buckwheat, sorghum, radish, beans, and white mustard. Microbiological analysis was carried out using the dilution method and phytotoxicity assay according to ISTA filter paper method (germination energy (GE), germination (G), root and shoot length, fresh and dry weight). The sample was slightly contaminated with domestic, industrial, and agricultural xenobiotics and had low levels of nitrogen substances, metals, and organic micropollutants. Pesticides, metolachlor, tebuconazole, propiconazole, imidacloprid, and thiametoxam were detected at levels exceeding the maximum admissible concentrations (MACs), i.e., the sum value for neonicotinoids. The number of saprophytic (2.27 x 10(6) CFU mL(-1)) and coliform bacteria (5.33 x 10(2) CFU mL(-1)) was very high. The total number of sulphite reducing clostridia (10 cells mL(-1)) and Escherichia coli (5 cells mL(-1)) was very low. The GE and G of all tested plants, except sunflower, were not influenced by the total chemism of water sample. However, it inhibited root lengths of sunflower, cucumber, maize, and barley and stimulated shoot lengths of all species except maize and white mustard. These results indicate that it can be used for irrigation of cabbage and radish from the chemical point of view, but the microbiological traits should be considered prior to consumption since they are consumed raw. The overall results suggest that water from Stara Tisa should be purified before using for agricultural purposes.

AB  - Nicosulfuron is one of the most applicable sulfonylurea herbicides for control of annual and
perennial weeds in maize. Its residues can persist in soil at phytotoxic concentrations and affect
sensitive succeeding crops more than one season after treatment. Therefore, monitoring the
trace levels of this herbicide in soil is a challenging task and demands highly efficient, selective,
and sensitive analytical technique. This study was conducted for the purpose of investigating
nicosulfuron residues presence in soil. Soil samples were collected before crop seeding, from
two soil layers, surface (0-30 cm) and sub-surface (30-60 cm). Nicosulfuron determination and
quantification were performed by HPLC with diode-array detection, using isocratic elution of
mobile phase. Nicosulfuron was extracted from the soil sample with mixture of phosphate
buffer (pH 7.4)/methanal (80/20, v/v) solution with clean-up on C18 extraction cartridge. The
linearity of detector response showed that the calibration curves were linear with correlation
coefficient (R’) of 0.999. Relative standard deviations (RSD) of the retention times and of the
peak areas were 0.79 and 1.06%, respectively and fulfilled the criteria of chromatographic
measurements. The accuracy of the defined method was confirmed by the good results of
recovery assay, while achieved limit of detection (LOD) and limit of quantification (LOO) for
nicosulturon in soil were in accordance with SANCO/825/00 (SANCO, 2010). The proposed
analytical procedure was applied for monitoring of nicosulfuron herbicide in soil. Average values
of nicosulfuron residues in soil samples from surface and sub-surface horizon were 0.05 mg/kg.

AB  - The aim of this work was to determine the surface tension and suspensibility of spray liquids of fungicides (Quadris and Dithane M-70), insecticides (Actara WG-25 and Cipkord EC-20) and two and/or three component mixtures with non-pesticide substances (complex fertilizer - Mortonjic plus and - aduvant - Sillwet L-77), depending on water quality. For this work the following waters were used: well water from Becej (slightly alkaline, slightly soft), well water from Adice (slightly alkaline, very hard), tap water from Novi Sad (neutral, slightly hard) and surface water from Sava and Karas rivers (slightly alkaline, slightly hard). Surface tension of fungicide and insecticide spray liquids and their mixtures in mentioned waters was determined using tensiometer and suspensibility according to a standard method (CIPAC MT 15). The surface tension of all tested waters was high. However, the reduction of surface tension by 50% (or more in water from Sava river) compared to the control waters, was achieved by adding the aduvant (Sillwet L-77) and insecticide formulated as emulsifiable concentrate (Cipkord EC-20). Surface tension was slightly decreased in a single component spray liquids of fungicides and the complex fertilizer, as well as in mixtures that did not contain aduvant and/or Cipkord EC-20, regardless on water quality. Suspensibility of all spray liquids, regardless on tested water was above the lower limit (60%). In general, the suspensibility in case of all mixtures containing Dithane M-70 was reduced compared to Dithane M-70 spray liquid, in all tested waters. The most pronounced decrease in suspensibility, below 70%, was registered in the case of spray liquids with tap water, compared to others (99.8%).

AB  - In this study, applicability of extracts from fava bean seeds (Viciafaba L.), as natural coagulants, was investigated. Coagulants were obtained by extraction, with distilled water or NaClsolutions, from grinded seeds and were applied as coagulants, in various doses, in synthetic water having different initial turbidities and pH values. Presence of NaC1 in water showed that increasing the ionic strength results in greater amount of extracted compounds, but it does not affect coagulation activity. Appling different doses of coagulant in water showed that the best coagulation activity is achieved by adding dose of 0.125 m1/1. The conducted experiments confirm positive coagulation properties of these extracts, therefore it can be concluded that they have great potential as natural coagulants. C) 2015 Elsevier B.V.

AB  - Prosulfuron, rimsulfuron, thifensulfuron-methyl and tritosulfuron are widely used
sulfonylurea herbicides (SUs), applied in low-dose rates. However, these herbicides under
specific conditions as low temperature, poor rainfall, microbial activity. high pH of soil, can
remain at low concentrations in soil and can affect the growth of sensitive plants. This paper
presents the method that we developed for determination of prosulfuron, rimsulfuron,
thifensulfuron-methyl and tritosulfuron residues in soil. Determination and quantification
were performed by HPLC/DAD using Agilent Zorbax SB-C18 column (3.0 mm*250 mm. 5
um particle size). Mobile phase was acetonitrile/0.1% CH3COOH solution. Analyzed SUs
showed linear calibrations from 0.05 to 0.2 mg/ml with correlation coefficient (1°) above
0.990%. The recovery data were obtained by spiking blank soil samples at two concentration
levels (2.5-5.0 mg/kg), yielding average recovery between 95.56 and 99.79%. Precision
values expressed as relative standard deviation (RSD) were between 0.91-1.11% for all SUs
herbicides for the intraday precision. Considering the obtained values of analytical
parameters, the proposed method proved to be an efficient and sensitive method for the
determination of prosulfuron, rimsulfuron, thifensulfuron-methyl and tritosulfuron in soil
samples.

AB  - The aim of this study was to carry out comparative assessment of pollution level of water from Aleksandrovacki canal, Serbia, using both chemical methods and phytoindicators, and to estimate its potential use for irrigation of four most commonly cultivated plant species in this area (maize, barley, cucumber and white mustard). The effect of water quality and/or pollution was assessed in bioassay, according to changes in physiological (seed germination energy, germination) and morphological parameters (root and shoot length -cm and fresh and dry weight of root and shoot-g) of tested species. The chemical analysis of water determined a high content of suspended substances, nutrients, ammonium ion, total nitrogen, organic matter with low degradability, total organic carbon, orthophosphates, total phosphorus, arsenic and chromium. The response of phyto-indicators to water quality and mixed pollution was species-dependant. Germination of maize, cucumber and white mustard was not under the influence of water quality, while barley seeds germinated in significantly lower percentage in water from the canal (95%) compared to the control (100%). Canals water inhibited root elongation of maize and barley and stimulated of white mustard (p lt 0.01) compared to the control. Shoot length of barley, cucumber and white mustard was not under the influence of water quality (p>0.05). Biomass was differently affected by water from the canal.

AB  - A reduction in pesticide effectiveness, in general, may be due to hydrolysis. The rate of hydrolysis is dependent on pH, pesticide chemistry, length of time in the spray tank and water
temperature in the spray tank. The exposure of the spray tank to sunlight will also impact the
rate of hydrolysis. The present work describes stability test of bentazon and dicamba in water
under different conditions, such as pH, presence or absence of sunlight and different
temperatures. Stability of bentazon and dicamba aqueous solution was assessed by exposing
aqueous samples to different temperatures, different pH (4, 7 and 10) and presence or absence
of sunlight. The stability study under laboratory conditions revealed high stability of both
compounds in aqueous solution pH 10, when exposed to sunlight or darkness. Dicamba was
stabile at pH 7, while in aqueous solution pH 3 degraded 30% of initial concentration of
dicamba. Bentazon degraded more that 50% after two weeks at pH 4 and 7.

AB  - Non-point-source contamination of surface water has emerged as an important environmental problem during the last decades. This is particularly obvious in areas with intensive pesticide application. Considering importance of water and soil quality, pesticide residues in our environment need to be more effectively documented. This study has focused on determination of pesticide residues in drainage water. Monitoring of pesticide residues were conducted at different locations in the northern part of Serbia, the main agricultural area of the country. The sampling was performed during spring and summer 2012 on twelve potential risk sites. The extraction of pesticides from water was carried out with ENVI™ C18 DSK 47 mm (Supelco 5-7171, Bellafonte, PA). Prior to extraction disc was conditioned with 5 ml of methanol and 5 ml of ultrapure water. Afterward, water sample was filtered through the disc under vacuum and disc was dried for 1 h at 25 °C. Pesticides were eluted from the disc with 5 ml of mixture dichloromethane/n-hexane (40/60, v/v) and evaporated to dryness. The extract was reconstituted in 1 ml of methanol, ultrasonically homogenized and analyzed. Analyses were performed on Agilent Technologies GC-MS Model 7890 A Series gas chromatograph coupled to 5975 C mass selective detector. A HP5MS (30 mx 0.25 mmi.d.) fused silica capillary column was used. Helium was used as the carrier gas at a constant pressure. Injection volume was 2.0 ul, in splitless mode at 280 °C. The total run time was 41.86 min. The interface was kept at 250 °C, the quadropole at 150 °C and the mass spectra were obtained at electron energy of 70 eV. After validation and measurement uncertainty evaluation steps, results obtained showed that the method can be applied to efficiently for monitoring of pesticide residues in water samples. In analyzed samples 22 pesticides were detected -8fungicides,9 herbicides and 5 insecticides. Herbicides were most frequently detected (in 41% of the samples), followed by fungicides (36%) and insecticides (23%)

AB  - The characteristics of water used in a spray mix influence the
effectiveness of pesticides. It is important to know the pH of water used
with a pesticide and the susceptibility of the pesticide to hydrolysis.
In order to investigate the persistence, dissipation and degradation
kinetics of bentazone and dicamba, laboratory study was conducted
in deionized water (pH 7.0) at 2542°C (T1) and 442°C (T2). Herbicides
were dissolved at rate of 0.05 mg/ml. Concentration of analytes was
monitoried 0 (1h), 2, 4, 7, 10, 14, 18, 24 and 28 days after treatment and
analysing as triplicate samples. Samples were analyzed by high pressure
liquid chromatography (HPLC/DAD). The chromatographic separation
was carried out with Zorbax Eclipse XDB-C,, (50 mm x 4.6 mm x 1.8 pm)
analytical column, using reverse phase column with gradient conditions
of mobile phase consist of water (with 0.05% H PO,) and acetonitrile. In
T1 the dissipation were 1.3, 5.1, 7.5, 7.9, 8.1, 15.3, 24.1, 26.9% for dicamba
and 11.5, 33.3, 44.6, 46.9,48.8, 49.6, 50.1, 51.8% for bentazone in 2, 4, 7,
10, 14, 18, 24, and 28 days. Corresponding dissipation in T2 experiment
were 2.0, 2.7, 3.9, 5.0, 6.1, 6.9, 6.8, 8.0% for dicamba and 7.7, 15.2, 26.7;
29.4, 30.3, 30.6, 31.4, 31.9% for bentazone, respectively. The dissipation
data in water showed the DT, and DT,, values 57.3 and 114.9 days
ae for dicamba and 17.1 and 125.9 days for bentazone herbicide. Several
simulation models were used to evaluate the experimental data, such
as Exponential and Mittag-Leffler function. The dissipation of analized
eo . herbicides residues over the time in water were described by the MittagLeffler function, with the best-fit model for dicamba and bentazone [1].
The dissipation of dicamba and bentazone residues on 25+2°C and 442°C
es over the time in deinoized water were described by function a*Eo, (-bt).
ag Coefficients a, b, a, 8 were obtained from the experimental data by using
be fitting procedure. We got for dicamba and bentazone herbicides on
a 25+2°C coefficients a=0.8, R=3.71,a=159.11,b=12.79 and a=2.17, B=4.56,

rs G=3.15, a=205.81, b=0.117, respectively. The hydrolysis study indicated 
that the dicamba and bentazone pesticides hydrolysed faster at 25+2°C.
These findings can be useful in the prediction of the dissipation behavior
of this pesticides in the spray tank immediately before application. The
dissipation rates of dicamba and bentazone pesticides depended on the
temperature and pH of water to be used.

AB  - In plant protection a number of pesticide products, depending on formulation type, is applied previously diluted in water which differ in quality. The aim of the study was to determine the effect of water pH on pH value of spray liquids of fungicides (azoxystrobin, mancozeb), insecticides (thiamethoxam, cypermethrin), non-pesticide substances (complex fertiliser, adjuvant) and their mixtures. pH values of spray liquids were determined potentiometrically, immediately after preparation and after 24 h in the following waters: well water (Adice) - slightly alkaline (pH 7.90, 34.7 d degrees H, NO(2)2.5mg/l); tap water (Novi Sad) - neutral (pH 7.42, 15.4 d degrees H) and surface water (Sava) - slightly alkaline (pH 8.15, 11.7 d degrees H, NO2 0.18 mg/l, NH3 0.93 mg/l). Regardless of quality and pH of the water and pesticide compounds, pH value of spray liquids without complex fertiliser was in the range from 7.3 to 8.2 from application to 24 h. However, regardless of pH of water and pesticide compounds, all variants containing complex fertiliser had pH between 5.7 and 6.9, which points to possibility of correcting pH values of spray liquids with this fertiliser when the time of pesticide application coincides with fertilisation.

AB  - The intensive use of atrazine herbicides in the Republic of Serbia during recent decades has led to the accumulation of residues of atrazine and its metabolites in the environment, which endangers groundwater. With the objective to check the presence of atrazine and its metabolites deethylatrazine (DEA) and deisopropylatrazine (DIA) in the groundwater, the monitoring programme was carried out over the period from 2007 to 2009 in the localities where the atrazine-based herbicides were intensively applied for a number of years. Samples were taken from 327 localities, in total there were 1408 samples of groundwater of the first welling-up collected. The atrazine and its metabolites were extracted with methanol by means of ENVI-C18 (47mm) disc, and the residue level of the studied compounds was analyzed with gas chromatography-mass spectrometry (GC-MS). In the most of groundwater samples collected from agricultural regions, the average value of all tested analytes was above 0.1 µg/dm3. The highest values of atrazine and its metabolites were in the localities that are known for intensive maize production and in the areas of this region under orchards and vineyards, where atrazine was used in large quantities. The average content values of this active substance in the analyzed samples are the result of intensive and long-term usage of this group of herbicides, as well as the high level of groundwater in this region.

AB  - Pesticides are used worldwide within agriculture to protect crops and ensure the quantity and quality of the harvest. However, intensive and inappropriate pesticides application can directly or indirectly affect different parts of the environment, especially water source. Besides the occurrence of pesticides in drinking water, control of pesticide presence in surface and groundwater is also very important. This primarily refers to the drainage water, river and groundwater, considering the importance of environmental protection and food safety production. The presence of pesticide residues in these matrices may cause yield reduction and decrease product quality, due to its uptake. Objectives of this study included drainage water investigations to identify residue levels of selected pesticides. The sampling was performed during June 2012. Water samples were taken from drainage canals, on twelve sampling points, in intensively cultivated regions of Serbia, Vojvodina Province. Pesticides were chosen based on the European Union Directive 2008/105/EC. This directive by Annex X defines the List of priority substances in the field of water policy. List includes 33 pollutant - 9 are pesticides. The extraction of pesticides from water was performed using 018 ENVI (TM) disc (47 mm). Prior to extraction disc was conditioned with 5 ml of methanol and 5 ml of deionized water. Afterward, water sample was filtered through the disc under vacuum. After drying under vacuum (25 degrees C for 1 h), pesticides were eluted from the disc with 5 ml of mixture of dichloromethane/n-hexane (40/60, v/v) and evaporated to dryness. The extract was dissolved in 1 ml of methanol, ultrasonically homogenized and analyzed. The pesticide residues concentrations analyzed by gas chromatography/electron capture detection with Ni-63. Identification is performed by the use of GC/MS. The mean recovery of this extraction method for all analyzed pesticides at 1 mu g/ml, 0.1 pg/ml and 0.01 pg/ml spiking levels was 93.6%, with associated standard deviations (RSD) of 2.7. The limit of quantification was 0.01 pg/ml. Method accuracy was quantified through measurement uncertainty estimate based on method validation data. The combined relative uncertainty for water samples was 0.481%, while the expanded uncertainty (Us) calculated as U-c=k*U-c, where k is the coverage factor with level of confidence of approximately 95% considering a coverage factor of 2 (EURACHEM/CITAC, 2000), was 0.962%. Obtained values of evaluated analytical parameters are completely in accordance with regulations for analysis of pesticides trace level. Described method was applied for determination of above mentioned pesticides in real water samples. Finally, acetochlor, alachlor and chlorpyrifos were detected in drainage water samples collected in the agricultural area of Serbia.

AB  - Chlorpyrifos is one of organophosphorus (OPPs) insecticides, which are the most important and widely used classes of agricultural pesticides. Because of its intensive use of ecosystems are contaminated by chlorpyrifos and public concerns on safety have been increased.
The method has been developed for confirmation and quantitation of the chlorpyrifos in water samples reverse phase high performance liquid chromatography (HPLC) with photodiodes detection and chromatograms were extracted at 300 nm. This method was single-lab validate in order to demonstrate its performance for monitoring of the insecticide chlorpyrifos in water.
Method accuracy was quantified through measurement uncertainty estimate based on method validation data. Tap and groundwater samples were used to demonstrate linearity and accuracy. Linearity for chlorpyrifos was evaluated by calibration curves in the range of 0.01—10 pg/ml. The accuracy of the proposed method was evaluated as the mean recovery. The analytical method allowed us to quantify chlorpyrifos in tap water and groundwater in concentration level between 0.01-—10 pg/ml with recovery values between of 80.72-109.57 % for tap water and 89.99-97.45 % for groundwater and repeatability lower or equal than 0.6% for both the matrices. The experiments showed that there were no interference peaks from the water matrix (tap and ground) on the elution region of the chlorpyrifos. The RSD values were satisfactory being in the ranges of 0.283-1.237 % (for tap water) and 0.681-3.887 % (for groundwater). The variation of the retention time was less than 0.05 % during these experimental series. The combined relative uncertainty for water samples was 0.481 % (for tap water) and 0.654 % (for groundwater). The expanded uncertainty (Uc) was calculated as Uc= k*u,, where k is the coverage factor with level of confidence of approximately 95% considering a coverage factor of 2 (EURACHEMICITAC, 2000).
We proved that the method was specific for determination of chlorpyrifos in the relevant matrices. After validation and measurement uncertainty evaluation steps, results obtained showed that the method can be applied to efficiently for monitoring of chlorpyrifos in water samples.

AB  - Chlorpyrifos (0,O-dietyl O-(3,4,5-trichloro-2-pyridy!) phosphorothioate) is the one of
the most widely used insecticides in the world and it is detected more frequently in
surface and groundwaters than any other organophosphorus insecticide. According to EU
Directive 2008/105/EC (Annex X) chlorpyrifos is classified as one of the most important
water pollutants. This study assessed the possibility of chlorpyrifos detection in samples
of tap water and groundwater.
Extraction of chlorpyrifos was performed using ENVI C18 SP disc (47 mm). Prior to
extraction disc was conditioned with 5 ml of acetonitrile/methanol (50/50, v/v) and 5 ml
deionized water. Under vacuum 500 mi of tap water / groundwater with added
chlorpyrifos standard solution in concentration 0.01-1.0 ug/ml, was filtered through the
disc. Disc was dried at 25 °C for 1h. Chlorpyrifos was eluted with 6 ml (2x3 mL) of
acetonitrile/methanol (50/50, v/v) mixture and evaporated to dryness. The extract was
diluted in 2 ml of acetonitrile/methanol (50/50, v/v). Analysis was performed with a
Hewlett-Packard (HP) model 5890 Series Il gas chromatograph with EC Ni” detector.
Determination conditions were — t °C of column 190 °C with an increase of 30
°C/min up to 275 °C, t °C of injector 230 °C and t*C of detector 300 °C. The linearity of
the method was evaluated by chromatographing chlorpyrifos solution in concentrations
0.001-1.0 pg/ml. Correlation coefficient (R*) was 0.995 % and limit of detection (LOD) and
limit of quantification (LOQ) were 0.004 pg/ml and 0.01 pg/ml, respectively. The average
recovery for tap water was 95.5 % and for groundwater 87.2 %.

AB  - The intensive use of atrazine herbicides in the Republic of Serbia during recent decades has led to the accumulation of residues of atrazine and its metabolites in the environment, which endangers groundwater. With the objective to check the presence of atrazine and its metabolites deethylatrazine (DEA) and deisopropylatrazine (DIA) in the groundwater, the monitoring programme was carried out over the period from 2007 to 2009 in the localities where the atrazine-based herbicides were intensively applied for a number of years. Samples were taken from 327 localities, in total there were 1408 samples of groundwater of the first welling-up collected. The atrazine and its metabolites were extracted with methanol by means of ENVI-C18 (47mm) disc, and the residue level of the studied compounds was analyzed with gas chromatography–mass spectrometry (GC–MS). In the most of groundwater samples collected from agricultural regions, the average value of all tested analytes was above 0.1 μg/dm3. The highest values of atrazine and its metabolites were in the localities that are known for intensive maize production and in the areas of this region under orchards and vineyards, where atrazine was used in large quantities. The average content values of this active substance in the analyzed samples are the result of intensive and long-term usage of this group of herbicides, as well as the high level of groundwater in this
region.

AB  - For determination of pesticide residues in water, the extraction has a very important place,
considering that many factors may significantly influence on the extraction. The aim of this study was
to examine the influence of sample volume and solvent ratio (dichloromethane/n-hexane) on
extraction yield of herbicide acetochlor from water. The extraction of pesticide from water was
carried out with Cig disc. Analyses were performed using gas chromatography/electron-capture
detection (GC/ECD). A response surface methodology (RSM) was used to determine the optimum
extraction conditions. The results show a good fit to the proposed model (R>=0.981). This optimized
method was confirmed with recovery test under recommended conditions and average value of the
recovery was >95 %. The experimental values agreed with those predicted, thus indicating suitability of the used model and the success of RSM in optimizing the investigated extraction conditions.

AB  - Soil and water of adequate quality are essential for food safety, However, the intensive use of pesticides,
especially triazine based herbicides, in recent decades, has led to an accumulation of their residues in the environment.
This essay presents the results of monitoring and analysis of atrazine residues in samples of ground water aquifer and
soil collected in the vicinity of wells, in areas under intensive agricultural production in the region of Srem, where
atrazine has been applied for many years. Residue levels of atrazine were analyzed by GC/NPD, and the results showed
that its average value in samples of groundwater was 0.123 mg/l, and 0.038 mg/kg in soil. These values indicate that
groundwater and soil from this region generally fulfill the requirements of agricultural production.

AB  - The quality of the water for irrigation in conventional, but especially in
organic food production is very important. The presence of pesticide residues in
water may cause yield reduction and decrease product quality, due to its uptake.
Chlorpyrifos is one of the most widely used insecticide in the world and it ts
detected in surface and groundwaters more frequently than any other
organophosphorus insecticide. Also, chlorpyrifos is one of the most important
water pollutants (EU Directive 2008/105/EC).
The aim of this study was determination of chlorpyrifos in river and
ground water, wich are widely used for irrigation in agricultural production. The
Extraction of chlorpyrifos was performed using ENVI C18 SP disc (47 mm).
Prior to the extraction disc was conditioned with 5 ml of acetonitrile/methanol
(50/50, v/v) and 5 ml deionized water. Under vacuum 500 ml of river and ground
water with added chlorpyrifos standard solutions in concentration 0.01-1.0 ug ml
', was filtered through the disc. Disc was being dried at 25°C for I h.
Chlorpyrifos was eluted with 6 ml (23 ml) of acetonitrile/methanol (50/50, v/v)
mixture and evaporated to dryness. The extract was diluted in 2 ml of
acetonitrile/methanol (50/50, v/v). Analysis was performed with a Hewlett—
Packard (HP) model 5890 Series II gas chromatograph with EC Ni®’ detector.
Determination conditions were — t °C of column 190 °C with an increase of 30°C
min’! up to 275°C, t°C of injector 230°C and t°C of detector 300°C. The linearity
of the method was evaluated by chromatographing chlorpyrifos solution in
concentrations 0.001-1.0 pg mI'. Correlation coefficient (R°) was 0.995 and limit
of detection (LOD) and limit of quantification (LOQ) were 0.004 pg ml! and
0.01 wg mI', respectively. The average recovery for river water was 87.5% and
for groundwater 97.9%.
