Trace element and heavy metal contents of agricultural and nonagricultural soils in the region of Banat

Abstract

Levels of trace elements and heavy metals were determined in samples of several representative types of agricultural soil (chernozem, humogley solonetz, cambisol and fluvisol) taken from 20 locations in the Banat region as well as in samples of several types of nonagricultural soil (nature reserves, national parks, industrial zones). None of the agricultural soils were deficient in Cu, Mn, Zn or Co. Also, none of the trace elements exceeded the maximum allowable concentration (MAC), except for a site near Vršac where the copper content was slightly above the MAC. The same was true of nonagricultural soils, even in the case of copper, which exceeded the MAC near Vršac. The heavy metal content did not exceed the MAC in any of the samples of either the agricultural or nonagricultural soils.

U uzorcima nekoliko reprezentativnih tipova poljoprivrednog zemljišta (černozem, humoglej, solonjec, kambisol i fluvisol) Banata, uzetih sa dvadeset lokaliteta, i nepoljoprivrednog zemljišta (rezervati prirode, park prirode, industrijske zone) određivan je sadržaj mikroelemenata i teških metala. Sadržaj mikroelemenata u poljoprivrednim zemljištima pokazuje da nijedan tip zemljišta ne pokazuje deficit u Cu, Mn,Zn, i Co,a takođe ni jedan mikroelement ne prelazi MDK sem u okolini Vršca gde je količina bakra malo iznad MDK. Za nepoljoprivredna zemljišta važi isto napred rečeno čak i za bakar koji u okolini Vršca prelazi MDK. Sadržaj teških metala u ispitivanim poljoprivrednim zemljištima ni u jednom uzorku ne prelazi MDK, što se može reći i za nepoljoprivredna zemljišta.
