The use of water lettuce (Pistia atratiotes L.) for rhizofiltration of a highly polluted solution by cadmium and lead

Popis výsledku v původním jazyce

The effectiveness of heavy metal uptake from contaminated nutrient solution by aquatic macrophytes (Pistia stratiotes L., Salvinia auriculata Aubl., Salvinia minima Baker, Azolla filiculoides Lam) was estimated. The influence of Cd (3.5 mg L-1 and 10.5 mg L-1) and Pb (25 mg L-1 and 125 mg L-1) on the stress symptoms was observed through the determination of chlorophyll content and transpiration rate over 14 days. The results showed extreme reductions in Cd and Pb concentrations in solution during first4 days. The accumulation of Pb in plant tissues was the highest during first 4 days and was more than 10 times higher in roots (42,862 mg kg-1) than in leaves (3,867 mg kg-1). The Cd accumulation slowly increased and was the highest at the end of the experiment. Concentrations in roots (3,923 mg kg-1) were roughly 6 times higher than in leaves (624 mg kg-1). Results significantly showed decrease in the transpiration rate at Pb treatment and increase at Cd treatment during 48 hours of exp
