Heavy metals pollution is a global issue in the whole word. All soils contain heavy metals, but their concentrations usually are very low. According to the literature, bird’s-foot trefoil (Lotus corniculatus) is used as adsorbent of heavy metals from soil. The study was achieved in Copșa Mică area, known for a long time in the top of the most polluted cities in Europe, due to the emissions from two factories. In article it is described the correlation between total forms and DTPA extractable forms and concentrations in Lotus corniculatus plants of cadmium, lead, copper and zinc. In conclusion, cadmium was most easily absorbed of Lotus corniculatus, while lead was identified as having the lowest accumulation in Lotus corniculatus, so it can be used for the removal of some heavy metals from soil.
