Abstract
The objective was to look at the effect of anthropogenic activities on the accumulation of heavy metals; in four legumes crop plants. Pisum sativum L., Vicia faba L., Glycine max and Vigna sinensis, during summer and winter plants exposed to five levels of ambient air pollution by quantifying heavy metals (Cu, Mn, Pb and Zn) concentrations in the leaves, pods and grains. Results indicated that air pollution significantly increased the heavy metal concentrations in the leaves, pods and grains. Toxic concentrations were found in the plants grown at L3, L4 and L5.
