This study aims to investigate the accumulation of heavy metals (Cd, Pb, Zn and Cu) from soil in red clover (Trifolium pratense L.) plants in experiments with single-element induced pollution, carried out in the greenhouse. The soil used comes from an unpolluted permanent meadow in the Copsa Mica area and was analyzed from a physico-chemical point of view. The total contents of heavy metals fall within the normal limits according to Order 756/1997 on the assessment of environmental pollution. To perform the experiments with induced pollution, the soil material was treated with variable amounts of metal (Cd, Cu, Pb and Zn) from their soluble salts, and for each element 6 experimental variants were established depending on the metal content in the soil. The results show that for the total cadmium and lead contents in the soil and the metal content in the plant, extremely significant linear correlation indices were obtained and for zinc and copper very significant. The mobile metal contents in the soil and the metal content in Trifolium pratense plants have a very significant linear correlation index.
