Abstract
The uptake of cadmium and lead by three lettuce (Lactuca sativa L.) cultivars was studied in water culture experiment. Different amounts of cadmium (Cd) and leaf (Pb) were added to the nutrient solution (0; 0.05 μM Cd; 0.5 μM Cd; 0.05 μM Pb; 0.5 μM Pb; 0.5 μM Cd together with 0.5 μM Pb). Fresh and dry matter yield of leaves and roots were significantly reduced by the presence of 0.5 μM Cd and 0.5 μM Cd together with 0.5 μM Pb. The higher the Cd or Pb concentration in solution the more Cd and Pb accumulated in the plants. Most of the accumulated heavy metals were located in the roots. The combination of Cd and Pb in the nutrient solution had an additive effect on most investigated parameters. The presence of lead alone, almost in all cases, did not effect the concentration of macro- and microelements. Cadmium in concentration 0.5 μM Cd and Cd together with Pb caused a significant increase of the Ca and Cu contents in shoot content of Pb. Roxette accumulated the least Pb in the roots at 0.5 μM Pb whereas Pia the least when both Cd and Pb were present in the solution.
