摘要
本研究建立了应用单项污染指数及内梅罗综合污染指数法评价生乳中重金属的污染情况的方法,以分析不同地区的污染情况;并且对于生乳中低浓度的重金属残留及没有残留限量的重金属残留,以慢性非致癌性风险HQ值进行描述,与参考剂量相比较,进而确定其对于成人饮用的安全性。对中国2个奶业主产区的20个生乳中的砷、铅、铬、汞、铝、镍进行了污染分析及危害描述,证明了本方法的合理性和适用性。
A risk analysis with single factor index and Nemerow multifactor index method was developed to evaluate the pollution levels of heavy metal in raw milk in different regions.And the non-cancer risk in the raw milk with low concentration pollution and non-residue limit was estimated using the hazard quotient(HQ).HQ was the ratio of the exposure estimate to the reference value.By the results,we could ensure the safety of raw milk.Twenty raw milk samples were collected from China's two of the main milk-producing regions.The pollution of arsenic,lead,chromium,cadmium,mercury,aluminium and nickel elements were analysed,the results indicated the samples collected from region B was higher than A,and the exposure of non-cancer risk of the concentration in all positive samples were far below the reference value.The rationality and applicability of this method were proved.
