浙江海域虾姑中重金属镉的监测及健康风险评估

Determination of Cd in Oratosquilla oratoria and Its Risks to Human Health in Sea Area of Zhejiang

[目的]监测浙江海域中虾姑的重金属镉的含量,并对其健康风险进行评估。[方法]以浙江附近海域捕获的虾姑为材料,根据GB5009.12-2010中的石墨炉原子吸收光谱法测定其体内的重金属镉含量,并利用健康风险指数的方法对多个菜场或码头采来的虾姑中镉的健康风险进行评估。[结果]试验发现,所采集的海捕虾姑样品中镉含量都符合国家规定标准,各个虾姑样品的健康风险指数均小于1,按照平均摄入量来计算,每个虾姑都是处于安全水平的。[结论]浙江海域虾姑镉含量未超标,健康风险指数也在安全范围内,且营养丰富,但摄入也应有一定的限值。

[ Objective ] To determine Cd in OrutosquiUa oratoria and evaluate its risks to human health in sea area of Zhejiang. [ Method] According to the graphite furnace atomic absorption spectrometry method in national food safety standard GBS009.12 -2010, Cd content of Oratosquilla oratoria captured in the Zhonshan Archipelago sea area were determinated. Human Health Risk Assessment Model was further used to evaluate the health risk of lead content of OratosquiUa aratoria in local markets and docks. [ Result] Data indicated Cd content in all the crabs meet the regulation in related standards prescribed by the state. The results of total assessment showed that the mean health index was less than 1. [ Conclusion] Cd content in Oratosquilla oratoria does not exceed the standard, health risk index is also within the scope of security.
