In this paper, we state briefly the research characterization of the heavy metals, their sources, risks, and pathway to transmit to human body through environmental media. Then, we review various methods of risk assessment for these metals on human health, ending with discussion about the research methodology and estimation results using dynamic modeling approach. Finally we developed a dynamic mathematical model. In this model, we incorporate indicators regarding residents who are potentially affected by in-taking doses of Cr, Cd, and Pb. We also describe the interrelation with the sources of pollutaons related to production activities and the transmission pathway of pollutants through the source to water-soil, and agricultural output.
