Content of heavy metals in surface floodwater and flooded soil on the territory of the municipality Sečanj

Abstract

This paper presents a part of the research related to the content of microelements and heavy metals in the floodwater and in the soil after the failure of the embankment on the river Tamiš in Rumania and the catastrophic flood during the second half of April 2005 on the territory of central Banal. Based on the results of the analyses of total contents of dangerous and harmful elements (copper, zinc, iron, manganese, cobalt, lead, cadmium, nickel and chromium) in the soil of the flooded area of central Banat, it can be concluded that the floodwater and flooded soil were not polluted by heavy metals, because the total concentrations of the study elements do not exceed the maximum admissible concentrations in any of the water or soil samples, according to the Regulation on the admissible values of dangerous and harmful substances in the soil and irrigation water and the methods of their analysis (Official Gazette of the Republic of Serbia 23/1994).

U ovom radu prikazan je deo istraživanja koja se odnose na sadržaj mikeoelemenata i teških metala u poplavnoj vodi, i zemljištu nakon probijanja zaštitnog nasipa reke Tamiš u Rumuniji i katastrofalne poplave u drugoj polovini aprila meseca 2005.god. na teritoriji srednjeg Banata. Prema rezultatima izvršenih analiza ukupnog sadržaja opasnih i štetnih materija (bakra, cinka, gvožđa, mangana, kobalta, olova, kadmijuma, nikla i hroma) u zemljištu na poplavljenom području srednjeg Banata, može se zaključiti da poplavna voda kao i zemljište nisu bili zagađeni teškim metalima, jer ukupni sadržaj ispitivanih elemenata ni u jednom uzorku vode I zemljišta ne prelazi maksimalno dozvoljenu koncentraciju prema Pravilniku o dozvoljenim količinama opasnih i štetnih materija u zemljištu i vodi za navodnjavanje i metodama njihovog ispitivanja (Službeni Glasnik Republike Srbije 23/1994).
