Effect of salinity and pH on the absorption of cadmium in Lemna minor

Rajaa Abdul-Kadhim Hanaf


This work was conducted to study the effect of salinity and pH on the absorption and accumulation of cadmium by the aquatic plant Lemna minor. Different concentrations of salinity (0, 1, 2 and 3 ppt) and pH (6.2, 7 and 8.4) were used. The results showed a decrease in the absorption of cadmium with increasing salinity, and the highest concentration of cadmium absorption at pH 6.2.
