Abstract: With the objective of evaluating the effect of cadmium (Cd) and lead (Pb) in the culture of mustard (Brassica juncea) and its relationship with plant development, levels, accumulation and translocation in roots and shoots, mustard plants were grown in Clark nutrient solution and subjected to increasing doses of Cd (0.00; 0.25; 1.00; 5.00 and 10.00 mg.L-1) and Pb (0.00; 2.50; 10.00; 50.00 and 100.00 mg.L-1). Cd showed a significant translocation into the plant, which is due to the formation of a complex between the chemical species and phytochelatin; the low translocation of Pb and deleterious effects are due to root deposits of Pb stable chelates.
