Content Analysis and Health Risk Assessment of Heavy Metals in Cultured Eel in Taishan City of Guangdong Province
Objective:To determine the content of Lead,cadmium,chromium,arsenic,mercury and copper in cultured eels,analyze their distribution,and evaluate their pollution characteristics and health risks.Method:Six kinds of heavy metals were determined by inductively coupled plasma mass spectrometry in cultured eels in Taishan city of Guangdong province.Inorganic arsenic was determined by high performance liquid chromatography-atomic fluorescence method.The difference and correlation of its content were analyzed by statistical method.The pollution level was evaluated by factor pollution index.Health risks of heavy metals were assessed by target risk quotient.Result:The detection rate of Cu,As,Hg and Cd was 100.0%,Cr was 72.8%,and Pb was 61.3%.The average contents of Pb,Cd,Hg,As,Cr and Cu were 0.036 mg·kg-1,0.009 mg·kg-1,0.070 mg·kg-1,0.348 mg·kg-1,0.064 mg·kg-1 and 0.401 mg·kg-1.The significant differences in heavy metal content was among different eel farms(P＜0.05).The pollution index and the health risk index were less than 1.Conclusion:The overall content characteristics of heavy metals were low and met the national food safety standards.the pollution indexes were within the normal range.The health risk of cultured eel is not obvious,and the food safety is good.
