散装白酒中铅的测定与健康风险评价
目的 研究长沙县地区生产的散装白酒中铅的含量, 并评价经居民膳食途径摄入重金属铅的健康风险。方法 采用原子吸收光谱法对长沙县内的76份散装白酒中的铅含量进行测定, 并运用内梅罗综合污染指数法、单因子污染指数法以及美国环保局推荐的目标危害系数法评价散装白酒中重金属铅污染状况及其健康暴露风险。结果 76份散装白酒样品中铅的含量在未检出~0.11 mg/kg之间, 均未超标; 所测样品的单因子污染指数和综合污染指数均小于0.7, 暴露风险指数均小于1, 表明样品中铅的含量处于安全水平, 且不存在重金属铅的健康暴露风险。结论 长沙县地区小作坊生产的散装白酒铅含量处于安全水平, 对当地居民不会产生经膳食途径摄入铅的健康暴露风险。
Objective To study the content of lead(Pb) in bulk liquor produced in Changsha county and assess the health risk of dietary intake of heavy metal lead. Methods The atomic absorption spectrometer were adopted to detect the Pb concentrationin 76 samples of bulk liquor in Changsha county. The contamination status and health risk of heavy metal lead in bulk liquor were assessed by the Nemerow comprehensive pollution index, single factor pollution index and target hazard coefficient methods recommended by the United States Environmental Protection Agency. Results The content of Pb in 76 samples of bulk liquor in Changsha country was in the range of 0~0.11 mg/kg, none exceeded the safety limitation. The Nemerow pollution index evaluation and single factor pollution index evaluation were all less than 0.7, and the exposure risk index of Pb in bulk liquor was less than 1, which showed that the lead content in the samples was at a safe level, and there was no health exposure risk of heavy metal lead. Conclusion The content level of Pb in bulk liquor produced by small workshops in Changsha country was safe, and will not cause health risk to the local resident through diet.
