AB  - Chlorpyrifos is one of the most frequently used insecticide worldwide
and it is more often detected in surface and ground waters compared to other
organophosphorus insecticides. Also, chlorpyrifos is one of the most important
water pollutants (EU Directive 2008/105/EC).
In this study a solid phase extraction method was developed for
determination of chlorpyrifos in surface and ground water, which are used for
irrigation in agriculture production,
Samples were prepared by spiking in 500 ml of water (surface and
ground) with standard chlorpyrifos solution at rates 0.01-1 g/ml. Extraction was
carried out using ENVI C18 SP disc (47mm; Supelco No. 57171). Prior to
extraction, the disc was conditioned with 5 ml of acetonitrile/methanol (50/50,
v/v) mixture and 5 ml of deionised water. Chlorpyrifos was eluted from the disc
with 6 ml (2x3 ml) of acetonitrile/methanol (50/50, v/v). Eluent was evaporated
till dry, than diluted in 2 ml of acetonitrile/methanol (50/50, v/v) and
homogenised with ultrasound.
Chlorpyrifos content was analyzed using gas chromatograph (HP 5890 series II) with EC Ni® detector (column SUPELCO 24048, SPB'™-S,
30mx0.32mm, 0.25um FILM; gas carrier He). Injected volume was 2ul.
Determination conditions were — column temperature 190°C, increase of
30°C/min, final temperature 275°C; injector temperature 230°C; detector
temperature 300°C.
Linearity of detected response was determined by injecting standard
chlorpyrifos solution at rates 0.001-1.0 pg/ml. Correlation coefficient (R°) was
0.995 %. Limit of detection (LOD) for analyzed chlorpyrifos was estimated from
the fortified samples, while the limit of quantification (LOQ) was calculated from
LOD. LOD and LOQ were 0.004 pg/ml and 0.01 pg/ml, respectively. Average
recoveries of chlorpyrifos detection method in surface water were ranged from
84 % to 89 %, and in groundwater from 87 % to 95 %.

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  - The quality of water and soil in agricultural production are very important. The intensive use of the herbicide atrazine in Serbia during the last decades, has led to the accumulation of residues of atrazine and its metabolites in the environment. This study was conducted in order to verify the presence of atrazine and its metabolites residues in groundwater and the presence of atrazine residues in soil in the region of northern Serbia, where due to intensive agricultural production, atrazine has been applied in large quantities (2-20 kg/ha) for many years. Groundwater aquifer and soil samples from the arable layer (0-30 cm) were collected from 15 sites in the region of northern Serbia in the vicinity of wells that were used as source for water samples. The extraction of atrazine and _ its metabolites, deethylatrazine (DEA) and deisopropylatrazine (DIA) from water was carried out with methanol using C-18 DSK 47mm (Supelco No.57171), while the extraction from soil samples was conducted with Soxhlet - methylene chloride. Residue levels were analyzed by GC/NPD. The average concentration values for atrazine, DEA and DIA in groundwater samples wer 0.123yug/ (0.001-0.43yg/), 0.06yg/ (0.001-0.5yg/l) and 0.27pg/ (0.01-2.02yg/l) respectively. In 47% of the analyzed groundwater samples the concentration of atrazine and/or its metabolites was above O.1pg/. The average value of atrazine concentration in soil samples was 0.038mg/kq (0.001-0.155mg/kg). According to theRegulations of the Republic of Serbia the maximum level of atrazine in soil is declared respectively for sensitive crops and range from 0.06 to 1.0mg/kg. The result is a consequence of intensive and long-term usage of this group of herbicides, as well as the high level of groundwater in this region. The use of atrazine was recently banned in Serbia and we can expect a gradual reduction of its residues in this region.

The samples were iested for the content of 75 pesticides with LOD of 0.001 to 0.005 mg/kg which were
lower than MRLs according to the EU standards. The relative standard deviation was lower than 19% for
all the tested compounds. In the apple samples taken during 2004, the percentage of the samples positive to the pesticide residue content was 51.85% and the most frequent contaminants were *} HCH and
endosulfan. In the analyzed samples, taken during 2005, out of 70.91% samples in which the pesticide
residues were detected, endosulfan was present in 41.03%, captan in 35.9%, chlorpyrifos in 20.51% and
parathion in 17.95%. The content of the procymidone and lambda-cyhalothrin residues were over the EU
MALs. During 2006 all apple samples were residue-free. Out of 13 samples analyzed in 2007, five contained the pesticide residues below the EU MRLs with the most frequently detected dithiocarbamate.

AB  - The residues of pesticides in fruit are the consequence of their direct application in the agricultural production. In order to comprehend in what condition
the pesticide residues in fruit are and how hazardous they are to human health, it is
essential to carry out a long-lasting monitoring of their residue content and to create a
data base and a base of contaminant contents.
The fruit consumption nowadays is increasing in the world, almost 170
kg/person/year. Since the pesticides are widely used for fruit protection at present,
their excessive use can jeopardize human health so the content of their residues must
be checked on.
Our study comprised the determination of pesticide residue content in 108
samples of apples from the market of the Republic of Serbia taken during 2004-2007
(27 samples were analyzed in 2004, 55 samples in 2005, 30 samples in 2006 and 13
samples in 2007). The pesticide residues were determined by gas chromatography with
NPD, ECD and GLC - MS. The samples were tested for the content of 75 pesticides with
LOD of 0.001 to 0.005 mg/kg which were lower than MRLs according to the EU
standards. The relative standard deviation was lower than 19% for all the tested
compounds. In the apple samples taken during 2004, the percentage of the samples
positive to the pesticide residue content was 51.85% and the most frequent
contaminants were £ HCH (50% of positive samples) and endosulfan (28.57%) whereas
the content of all the other pesticide residues was below the EU MRLs. In the analyzed
samples, taken during 2005, out of 70.91% samples in which the pesticide residues
were detected, endosulfan was present in 41.03%, captan in 35.9%, chlorpyrifos in
20.51% and parathion in 17.95% (with 71.43% residue over the EU MRLs) samples.
The content of the procymidone residue was detected in two samples as well as
the content of lambda-cyhalothrin found in one sample was over the EU MRLs. During
2006 thirteen samples of apples were analyzed in which no pesticide residues were
detected. Out of 13 samples analyzed in 2007, five contained the pesticide residues
below the EU MRLs with the most frequently detected dithiocarbamate (3 samples).
The high percentage of samples positive to the pesticide residue content is a
warning that in the production conditions a continuous and multi-level monitoring of
food safety needs to be a regular practice aiming at the successful prevention of
harmful effects of pesticides on the health of people and animals.

AB  - The fruit consumption nowadays is increasing around the world, almost 170 kg/person/year [1] present, the pesticides are widely used for fruit protection and their excessive use may be harmful to people’s health so the content of their residues needs to be controlled. Our studies comprised the determination of the pesticide residues content in 297 fruit samples from the market of the Rep of Serbia taken during 2005-2007 (14 samples of blackberries, 16 samples of strawberries, 13 samples of plums, 182 of apples. 54 samples of raspberries and 18 samples of pears) by gas chromatography with NPD, ECD and GLC-MS. The samples were tested regarding the content of 75 pesticides, with LOD from 0,001 to 0.005 mg/kg. Out of 13 samples of plums in 4 of them pesticide residues were not detected, while in the others procymidone, vinclozolin, endosulfan | methidathion, cypermethrin, lambda-cyhalothrin, furadan and SDDT+methidathion were present | All the obtained values were below the EU MRLs. In 182 samples of apples 56.59% did not cont pesticide residues while 25.32% samples contained endosulfan. Out of 7 samples positive to parathion 5 of them contained parathion residues over the EU MRLs. The two other samples contained lambda-cyhalothrin and procymidone respectively over the EU MRLs. The analyzed a ; samples of blackberries had the highest content of the residues of dithiocarbamate 64.29%, a chlorpyrifos 57.14% and vinclozolin 35.17% within the limits of the EU MRLs, while in two samples the residues were not detected. Out of 16 samples of strawberries two of them were W pesticide residues. Chlorpyrifos was detected in 9 samples out of which 2 were over the EU M dithiocarbamate were detected in 8 samples and out of 7 samples with parathion residues 3 of contained residues over the EU MRLs. One sample positive to cypermethrin and five samples
positive to dimethoate had the values over the EU MRLs.
