摘要(Abstract)：

为了解淮南市不同城区居民人发中Hg分布特征和影响当地居民人体Hg富集的因素。在淮南市市区选择68名正常状态下的居民头发,用氢化物发生-原子荧光法测定人发中总汞含量。结果显示:淮南市市区居民人发中Hg的平均浓度为(0.390±0.173)μg·g~(-1),Hg浓度主要分布于0~0.5μg·g~(-1)较低浓度区间内,占总样品数的77.94%;市区内人发中Hg平均浓度呈现出谢家集(0.468±0.144μg·g~(-1))>潘集(0.384±0.199μg·g~(-1))>田家庵(0.377±0.176μg·g~(-1))>大通(0.373±0.116μg·g~(-1));不同性别上,当地男性头发中Hg的平均含量为(0.436±0.188)μg·g~(-1),显著高于女性的(0.343±0.146)μg·g~(-1)(P=0.021<0.05);不同年龄段内,40~60岁年龄段居民头发中Hg平均含量最高,达0.445μg·g~(-1);不同工作、生活环境上,淮南市居民头发中Hg平均含量呈现出矿区>过渡区>对照城区,其Hg平均含量分别达(0.466±0.174)、(0.380±0.167)、(0.304±0.151)μg·g~(-1),矿区居民人发中Hg含量分别高出过渡区与对照城区居民人发Hg含量达22.6%和53.3%。相比较美国国家环境保护局提出的人发中Hg的参考剂量1μg·g~(-1),淮南市城区居民人发中Hg含量较低。但是对比非矿业活动区,矿区居民人发中Hg含量显著高于对照城区居民(P=0.0098<0.01),过渡区居民人发中Hg含量与矿区和对照城区差异性均不明显。
