浒苔对海水中重金属的富集研究及食用安全风险评估

Accumulation study of heavy metal in seawater and edible safety security risk assessment for Enteromorpha prolifera

摘要: 研究了浒苔（Enteromorpha prolifera）分别在镉（Cd²⁺，浓度分别为5、20、80μg/L）和铅（Pb²⁺，浓度分别为5、20、80μg/L）及对照组的海水中培养时，2种重金属在其体内的积累规律。结果表明，浒苔对Cd和Pb具有较强的富集能力，对Cd的富集倍数范围为558~1882倍，对Pb的富集倍数范围为6295~11080倍。本研究并对富集Pb和Cd后浒苔的食用安全进行风险评估。

Abstract: Taking Enteromorpha prolifera as research object, we establish the rule of accumulation of Cd and Pb in E.prolifera. The concentration in this experiment is as follows:Cd²⁺(5、20、80μg/L)、Pb²⁺(5、20、80μg/L).The experiment showed that E.prolifera had a high ability of accumulating Cd and Pb. The range of concentration coefficient for Cd is 558~1882,and for Pb is 6295~11080. Then we made edible safety security risk assessment for E.prolifera which accumulating Cd and Pb respectively.
