【摘要】：目的了解陕西省市售水产品的重金属污染状况及摄入风险。方法简单随机采集水产品331份并测定镉、砷、铬、铅、汞、镍的含量,采用单因子污染指数(Pi)、重金属污染指数(MPI)、每日可耐受摄入量(TDI)及致癌与非致癌年风险(Rcig,Rnig,R总)指标分别评价污染程度、食用安全性和健康风险。结果重金属含量均值水平为总铬镍总砷铅镉总汞,铅、镉、总铬的超标率分别为2.11%、0.30%和0%。不同水产品中重金属污染状况不同。Pi评价结果鱼类中镉、砷为轻度污染,其余均为正常背景值。MPI评价重金属污染总体程度为甲壳类软体动物鱼类。Dig(平均)占TDI百分比最高为镉、总铬,分别为27.84%和17.58%。结论陕西省市售水产品有一定程度的重金属污染,食用安全性在可接受范围内,摄入水产品健康风险较低。
[Abstract]:Objective to investigate the heavy metal pollution and intake risk of aquatic products in Shaanxi province.Methods 331 aquatic products were collected randomly and the contents of cadmium, arsenic, chromium, lead, mercury and nickel were determined.The pollution degree, food safety and health risk were evaluated by single factor pollution index (Piao), heavy metal pollution index (MPI), daily tolerable intake (TDI) and total annual risk of carcinogenic and non-carcinogenic (Rcig).Results the average level of heavy metal content was: total chromium, nickel, total arsenic, total lead, cadmium, total mercury, lead, cadmium, total chromium exceeded the standard rate was 2.11% 0.30% and 0% respectively.The results of heavy metal pollution in different aquatic products. Pi showed that cadmium and arsenic were mildly polluted in fish, while the others were normal background value. The total level of heavy metal pollution was: crustacean mollusk fish. Dig.Dig. the highest percentage of TDI was cadmium.The total chromium content was 27.84% and 17.58%, respectively.Conclusion there is some heavy metal pollution in aquatic products sold in Shaanxi Province. The edible safety is acceptable and the health risk of aquatic products intake is low.
