Acid Deposition Influence on the Biogeochemical Migration of Heavy Metals in Food Webs 

An interesting study of acid rain effects on the biogeochemical accumulation of heavy metals (Cd, Cu, Pb, and Zn) in crops has been presented by Chen et al., 1998. The authors have compared the ratios of relative concentration of four heavy metals in the brown rice and leaves of vegetables sampled from acid rain affected areas and 

Finally, this determines the exposure pathways and environmental risk values to human beings.
