Abstract: To analyze and evaluate the current situation of heave metal pollution in bivalve mollusks objectively, the survey results of heave metal concentrations in bivalve mollusks were evaluated according to the heave metal limit standards at home and abroad in this paper. The contents of heave metal in bivalve mollusks collected in our country were also analyzed by the method of risk assessment. The results showed that the concentrations of Cd and inorganic arsenic in bivalve mollusks sampled during the period from 2007 to 2009 exceeded the limit standards of China, but the theoretical most weekly/monthly intake (TMWI/TMMI) of the eating crowd was lower than provisional tolerated weekly/monthly intake (PTWI/ PTMI) posed by JECFA.
