Objective To understand food contaminants of lead and cadmiumin aquatic products in different city of Hainan. Methods Using graphite furnace atomic absorption spectrometry to determine lead and cadmium in 238 aquatic products, including fish, molluscs, crustaceans and bivalve. Analysis of metal content was performed based on the limits of harmful substances in pollution-free food and aquatic products. Results The content of lead and cadmium in aquatic products of Hainan province was in the range of 0.005~0.717 mg/kg and 0.100×10^-3~0.648mg/kg, lower than the limits of relevant standards in China. The maximum contamination of aquatic products was observed in bivalves. Conclusions The contamination of lead and cadmium in aquatic products in Hainan was safe according to the standards of China, the United States, Australia and Korea. The content of lead in some fish exceeded the standard of EU while the other products were qualified.
