Abstract Objective To analysis status of lead,cadmium and methylmercury residue in commercially available seafood during 2013—2015 in Zhoushan area.Methods During the period of 2013 to 2015,3 kinds of 1 134 seafood samples from representative farmer market in four districts of Zhoushan were collected to detect the lead,cadmium and methylmereury residue in seafish,mollusks and shellfish.Kruskal-Wallis rank-sum test were used to compare the difference of heavy metal residue in different years of seafood and exact propability were used to evaluate the difference of edible safety in different years.Results Of 1 134 seafood samples,the content of lead,cadmium and methylmereury was 0.011 5-0.555,0.000 3-0.328,ND-0.302 mg/kg,respectively.The over-standard rate of lead in 2013 and 2015 were 0.79% and 0.53%,found in five samples of seafish and shellfish,and the over-standard rate of cadmium in 2013 was 0.79%,found in three samples of seafish.Methylmercury residue in seafood wsa not found exceed the standard.Conclusion The contamination of lead,cadmium and methylmercury residue in commercially available seafood during 2013—2015 in Zhoushan area was in low level,but the content of lead and cadmium in seafood was over-standard.We should pay more attention to the lead content in shellfish,and lead and cadmium content in sea fish.
