CONTENTS OF CADMIUM (Cd), CHROMIUM (Cr) AND LEAD (Pb) IN THE AGRICULTURAL LAND IN THE DRY MASS ALFALFA FROM VARIOUS LOCALITIES

Abstract

This paper presents the results of the chemical analysis of the content of heavy metals (cadmium, chromium and lead) in the soils from the agricultural plots in four sites of the individual sector sown with the variety alfalfa Banat ZMS II. The test sites v. Jegunovce -Tetovo, v. Radusha -Skopje, and v. Kochilari -Veles are in the vicinity of certain pollutants (factory Jugochrom -Jegunovce, an abandoned mine for chromium and iron in Radusha, the smeltery of lead and zinc -Veles), while the v. Saraj -Skopje site is located in the middle of the noncontaminated environment and is taken for results comparation. The content of heavy metals (Cd, Cr and Pb) in the dry vegetation mass of the experimental alfalfa from the same sites was also researched in two phases of development where the following values were found such as <50 (Cd), <2.00 (Cr) and <2.00 (Pb) mg / kg dry mass, namely alfalfa selective capability to the analyzed heavy metals, besides their presence in soils, primarily chromium whose values were higher than the maximum permissible amount (>100 mg/kg soil).
