摘要
目的：研究砷污染地区居民砷暴露水平的分布特征。方法：分析污染区和对照区环境样品和居民头发砷含量。结果：污染区三个村土壤砷含量８４．１７～２９６．１９ｍｇ／ｋｇ。河水砷含量达０．５～１４．５ｍｇ／Ｌ，井水、自来水、食物含砷量一般符合国家卫生标准。砷摄入量１９５～１１２９μｇ／ｄ。居民头发砷含量中位数为０．９７２～２．４５９μｇ／ｇ。发砷值随年龄增加而增加。结论：石门雄黄矿附近地区河水砷污染严重，以河水为饮用水源的居民砷暴露水平达到甚至超过国内外重大慢性砷中毒案例的暴露水平。
Objectives:To investigate the levels of arsenic exposure of residents in the arsenic polluted areas near an arsenic mine.Methods:to analyse the arsenic levels in environmental samples and hair in the polluted areas and a control area.Results:In three villages of the polluted areas,arsenic levels in soil were 84 17 to 296 19mg/kg,in river water 0 5 to 14 5mg/L,in well water and tap water lower than 0 05mg/L,in rice 0 196 to 0 620mg/kg.Arsenic intake amounted 195 to 1129 μg/day.In the hair,the arsenic contents were from 0 972 to 2 459 μg/g,increasing with aging.Conclusion:In the areas near Shimen arsenic mine,arsenic pollution was serious.The levels of arsenic exposure of residents were equal to or even over that of the severe cases of chronic arsenic poisoning reported domestically and abroad.
