ASSESSMENT OF CU, PB, ZN AND CD AVAILABILITY TO VEGETABLE SPECIES GROWN IN THE VICINITY OF TAILING DEPOSITS FROM BAIA MARE AREA
In this study, the plant availability of Cu, Pb, Zn and Cd in plant soil-systems from the vicinity of tailing deposits in Baia Mare mining area was assessed. In order to evaluate the contamination level with heavy metals, aqua regia extractable metal contents from soil and tailings were determined. The DTPA extractable metals contents were correlated with those from carrots and cabbages. The results showed that significant percents of metals were extracted in DTPA and that soil and vegetables are highly polluted.
