Abstract:

Environmental Health Risk Assessment is an important method for quantitatively

describing the relationship between the pollution and the human health. This paper adopts

the theories and the models for Health Risk Assessment recommended by the U.S. Environmental

Protection Agency. We calculate the heavy metals intake risk through inhalation, foods,

drinking water and skins. The results suggest that the noncarcinogenic risk index is more

than 1, which  implies that they are the health risk for the residents in Deyang. The health

risk for people in Mianzhu and Jingyang is very high; the noncarcinogenic risk index for

these two areas are 776 and 4.36, respectively. Foods are a dominative factor for risk in

comparison to other ways. Although the results have some uncertainties, they are important

for the risk management in the study areas.
