RESEARCHES ON SOIL CONTAMINATION WITH HEAVY METALS AND THEIR REMANENCE IN VEGETABLES

 The paper presents the results of experimental researches on soil contamination with heavy metals (copper, lead, zinc) in different concentration each (c1=1.5 %; c2=3.0 %; c3=4.5 %; c4=6.0 %). The contaminated soil was placed in pots, where spinach and radish seeds were planted. The vegetables were grown in a greenhouse until the end of the vegetation period, afterwards being harvested and the remanence of each heavy metal for each concentration was determined for each plant. The results obtained were compared with the blank sample where the soil was not contaminated.        The purpose of the study was to identify the levels of heavy metals (Cu, Zn and Pb) transfer/absorption from the soil into spinach leaves respectively radish roots
