【摘要】：目的掌握湘潭、锡矿山地区居民人发锑含量暴露水平,为锑暴露风险评估提供基础数据。方法选择湘潭、锡矿山地区居民作为调查对象,收集人发104份,以原子荧光光谱法测定发锑含量并对结果进行分析。结果在73份湘潭地区居民人发中,总锑检出率为84.9%;测定值范围为ND~0.94μg/g。平均值为0.24μg/g,中位值为0.21μg/g。其性别、年龄差异无统计学意义(P0.05)。在31份锡矿山街道居民人发中,均检出锑,其检测值范围为1.65~70.00μg/g。平均值为20.80μg/g。中位值为13.00μg/g。结论湘潭地区居民锑含量主要分布范围为ND~0.30μg/g,处于较低水平,锑的环境暴露水平较低,生态环境未受到污染。锡矿山街道居民发锑含量主要分布在3.18~63.00μg/g区间,处于较高水平,锑的环境暴露风险较高。
[Abstract]:Objective to master the exposure level of antimony in hair of residents in Xiangtan and Ximine areas, and to provide basic data for risk assessment of antimony exposure. Methods 104 human hair samples were collected and the content of antimony in hair was determined by atomic fluorescence spectrometry and the results were analyzed. Results among 73 residents in Xiangtan area, the detection rate of total antimony was 84.9%, and the range of determination was ND~ 0.94 渭 g / g. The average value is 0.24 渭 g / g and the median value is 0.21 渭 g / g. There was no significant difference in sex and age (P 0.05). Antimony was detected in 31 street residents of tin mine, and the detection values ranged from 1.65 渭 g / g to 70.00 渭 g / g. The average value is 20.80 渭 g / g. The median value is 13.00 渭 g / g. Conclusion the main distribution range of antimony content in Xiangtan area is ND~ 0.30 渭 g / g, which is at a low level, the environmental exposure level of antimony is low, and the ecological environment is not polluted. The content of antimony in hair of Ximine street residents is mainly distributed in the range of 3.18 ~ 63.00 渭 g / g, which is at a high level, and the environmental exposure risk of antimony is higher.
