In the present paper indicated was the up take and accumulation of Cd and Pb by Brassi-ca chinensis grown in hydroponic culture,and the effect of Cd and Pb and their interactions onthe physiological and biochemical characteristics of Brassica chinensis. The experimental re-sults showed that Cd and Pb contents in plant was in positive correlation with the concentra-tions of Cd and Pb.The uptake of Pb by Brassica chinensis was inhibited by Cd.Cd, beyond acertain concentration,led to a reduction in chlorophyll ...
