【摘要】：[目的]了解上海市金山区市售动物性海产品中铅污染水平,评估当地居民食用市售动物性海产品的铅暴露风险。[方法]采用分层随机抽样方法采集151件市售动物性海产品,对其铅含量进行检测,并结合居民海产品摄入量调查,应用世界卫生组织推荐的食品中化学物质膳食暴露点评估方法,评估上海市金山区居民市售动物性海产品铅暴露风险。[结果]上海市金山区市售海产品中铅的平均质量分数(简称"含量")为0.194 1 mg/kg,P95为0.548 8 mg/kg,超标率为5.30%。不同人群中,孕妇平均每日经动物性海产品铅暴露量最大,为0.185 8μg(/kg·d),其次是3~5岁儿童,为0.176 7μg(/k·gd),最小的是乳母,为0.109 8μg(/k·gd)。海产品暴露高值人群(膳食摄入量P95)中,3~5岁儿童暴露量最大,为0.853 9μg(/kg·d),其次是孕妇,为0.598 3μg(/kg·d),最小的是乳母,为0.329 4μg(/kg·d)。[结论]上海市金山区孕妇和乳母市售动物性海产品中铅暴露情况总体处于安全水平,但对于海产品高消费儿童,存在铅暴露过多的风险。
[Abstract]:[objective] to investigate the level of lead pollution in animal seafood sold in Jinshan District, Shanghai, and to evaluate the risk of exposure to lead in the consumption of animal seafood by local residents. [methods] 151 samples of marketable animal seafood were collected by stratified random sampling, and their lead content was determined, and the intake of seafood was investigated. The risk of exposure to lead in animal seafood in Jinshan District of Shanghai was evaluated by using the method recommended by the World Health Organization (WHO) for evaluating dietary exposure points of chemical substances in food. [results] the average mass fraction ("content") of lead in seafood sold in Jinshan District of Shanghai was 0.194 mg / kg P95 = 0.548 8 mg / kg, and the rate of exceeding the standard was 5.30 mg / kg. Among the different population groups, the average daily exposure of pregnant women to lead in animal seafood was 0.185 8 渭 g(/kg DX, followed by children aged 3 to 5 years, 0.176 7 渭 g / kg GDP and 0.109 8 渭 g / kg GDP respectively. In the high value population (dietary intake P95), the exposure of children aged 3 to 5 years old was the highest (0.853 9 渭 g(/kg DV), followed by pregnant women (0.598 3 渭 g(/kg DX), and the lowest was the lactating mother (0.329 4 渭 g(/kg DU). [conclusion] the lead exposure of pregnant women and nursing mothers in Jinshan District of Shanghai is generally at the safe level, but there is a risk of excessive lead exposure for children with high consumption of seafood.
