Passive diffusion assessment of cadmium and lead accumulation by plants in hydroponic systems

Original language description

In experiments with willow planted in cadmium- or lead-contaminated Knopp nutrient solutions, the ability of willow and chelex gel in the diffusive gradient in a thin film (DGT) unit to sorb these elements was observed and compared. A method to compare the accumulated amount of metals by the willow and the sorbed amount of metals onto the DGT unit was designed. The accumulated/sorbed amount of metals was recalculated to the same units (&#956;g cm-2 day-1). The study of Cd(Pb) dynamic uptake by willow showed an exponential decrease of metal content in the exposure solution. The willow planted in the Knopp nutrient solution accumulated Cd(Pb) less than did the DGT unit in the same matrix. The willow planted in the soil/water system accumulated more leadthan did the willow in a lead-contaminated aquatic system nor did the DGT unit in the nitrate matrix. The willow further accumulated lead from the soil/water system due to the active co-uptake of nutrients and lead. The DGT technique was
