【摘要】 为评价中国典型水产品产地居民汞暴露的风险,分别在武汉、青岛和厦门三地系统采集139、136和159份当地居民头发样品,测定总汞含量并分析主要影响因素。结果表明:武汉、青岛和厦门居民（n=434）发汞（THg）的中位数（四分位数）为0.435 （0.262,0.820）μg·g^-1,武汉、青岛和厦门居民头发THg的中位数（四分位数）分别为0.392（0.253,0.611）μg·g^-1、0.305（0.204,0.478）μg·g^-1和0.814（0.445,1.350）μg·g^-1;三地分别有10位（7.2%）、8位（5.9%）和64位（40.3%）居民发汞超过美国环保署（USEPA）限值1μg·g^-1;厦门居民的发汞含量显著高于武汉和青岛（P<0.001）,居民的发汞含量与食鱼频率呈显著的正相关关系（P<0.001）;不同年龄段居民的发汞含量存在显著差异（P<0.001）,且在65岁后居民发汞逐渐降低;与以小麦为主食者相比,以大米为主食者其发汞含量增加的比数比（OR）（95%CI）值为6.47（4.07～10.29）;厦门地区居民存在一定的汞暴露风险,而武汉和青岛地区居民的汞暴露风险较低。更多还原

【Abstract】 To evaluate health risks of mercury（Hg） exposure for residents in typical aquatic production areas in China,a total of 139,136,and 159 human hair samples were collected from Wuhan,Qingdao,and Xiamen,respectively.Total mercury concentrations（THg） in hair samples were measured and the influencing factors were analyzed.The median（P25,P75） of hair THg concentrations in the whole population（n=434） was 0.435（0.262,0.820） μg·g^-1.The medians（P25,P75） of hair THg concentrations in Wuhan,Qingdao,and Xiamen were 0.392（0.253,0.611） μg·g^-1,0.305（0.204,0.478） μg·g^-1,and 0.814（0.445,1.350） μg·g^-1,respectively.7.2%,5.9%,and 40.3% of population from the three areas with hair THg concentrations exceeded reference value(1 μg·g^-1) set by U.S.Environmental Protection Agency,respectively.The highest mean value of hair THg was obtained in Xiamen.There were significant differences of hair THg concentrations between Xiamen and Wuhan,and between Xiamen and Qingdao（P<0.001）.There was a significant correlation between hair THg and frequency of fish consumption（P<0.001）.Hair THg varied among different age groups,with the highest value in the age group of 36-65 years.The averaged odds ratio（OR）（95% CI） value of increasing hair THg in population with rice consumption was 6.47（4.07-10.29） compared with the population without rice consumption.In conclusion,population in Xiamen is at high risk of Hg exposure,while the population in Wuhan and Qingdao are at low risk of Hg exposure.更多还原
