Abstract: Cadmium (Cd) and lead (Pb) were detected by atomic absorption spectrometry in ten kinds of common freshwater fish sold in Xiamen market. The results indicated that distributions of Cd and Pb in different parts (head, abdomen and back) on the ten kinds of freshwater fish were similar, but distributions of Cd and Pb in different fish were much different. Content of Cd in all fish samples were not exceeded, and content of Pb in 6.67% of fish samples exceeded China's national standards. WIestimate calculated by using Cd or Pb in each of freshwater fish as a single exposure ,was far less than that of the standard limit. Non-carcinogenic risk hazard quotient of Cd was 0~0.011, and non-carcinogenic risk hazard quotient of Pb was 0.093~0.569. Both of them were less than 1 which was within the safe range. All of these fish were safe to eat.
