摘　　要：根据我国饮水水质与水性疾病调查资料，统计了我国高砷饮水的地理分布和暴露人群。从２８８００多份水样测定得出：我国饮水中砷浓度０．０３０～０．０４９ｍｇ／Ｌ的饮用人口为９０２万人；水砷浓度为０．０５０～０．０９９ｍｇ／Ｌ的饮用人口为３３４万人；而水砷浓度＞０．１ｍｇ／Ｌ的饮用人口为２２９万人。全国大约有１４６０万人受到来自饮水砷（＞０．０３０ｍｇ／Ｌ）的暴露，占调查区人口的１．５％。高砷饮水主要是地下水。本文表列了各省、自治区、直辖市的饮水砷浓度状况，图示了这些高砷水的地理分布。According to the data obtained from the “National Survey on Drinking Water Quality and Waterborne Diseases”, the geographic distribution and exposure population of high arsenic drinking water were reported. From the data of more than 28800 water samples, we found 9.02 million people drinking the water with As concentration of 0.030￣0.049 mg/L,3.34 million people having their water of 0.050 ￣0.099 mg/L and 2.29 million people having water of>0.1 mg/L. A total of 14.6 million people, about 1.5% of the surveyed population was exposed to As (>0.030mg/L) from drinking water. 80% of high As drinking water was groundwater. The situation of As in drinking water in provinces, autonomous regions and municipalities were listed. The locations of sampling site where water As exceeded the national standard for drinking water were illustrated.
