【摘要】 为全面了解江苏近海动物性海产品中铅、镉、汞污染现状及食用风险，本研究于2022年4—11月在南通、盐城和连云港3个沿海城市的捕捞船、港口码头摊位、近岸养殖海域中采集了4类动物性海产品并进行了铅、镉、汞含量的测定。采用单因子污染指数、靶标危害系数法对重金属污染程度和食用风险进行评价。实验结果表明，本次监测的江苏近海动物性海产品镉超标率为5.4%,铅超标率为0.6%,所有样品汞浓度均在安全限值以内。镉单因子污染指数平均值为0.299,整体处于轻度污染水平；铅、汞单因子污染指数平均值分别为0.080和0.035,整体未受到铅、汞污染。4类海产品THQ值及THQs值均小于1,表明江苏近海动物性海产品中3种重金属元素暴露对人体健康风险较小。更多还原

【Abstract】 To comprehensively understand the current situation and consumption risks of lead, cadmium, and mercury in animal derived marine products in the coastal areas of Jiangsu, from April to November in 2022, four types of marine products were collected from fishing boats, port dock stalls, and nearshore aquaculture in three coastal cities of Nantong, Yancheng, and Lianyungang, and the content of lead, cadmium, and mercury were determined. Heavy metal pollution degree and consumption risk were evaluated by the single factor pollution index and target hazard factors method. The experimental results showed that the cadmium exceeding rate and lead exceeding rate of animal derived marine products in the coastal areas of Jiangsu were 5.4% and 0.6%, respectively. The mercury concentration of all samples was within the safety limit. The average value of cadmium single factor pollution index was 0.299, which is generally at a mild pollution level. The average values of single factor pollution indices for lead and mercury were 0.080 and 0.035, respectively. Marine products in the coastal areas of Jiangsu were not contaminated by lead and mercury. The target hazard quotients and the total target hazard quotients of the four types of seafood were all less than 1, indicating that there was little risk to human health from exposure to three heavy metal elements in marine products from the coastal areas of Jiangsu.更多还原
