摘　　要：目的分析新疆维吾尔自治区(简称新疆)阿克苏地区城乡居民饮水砷含量监测结果,了解各县市水砷含量分布及形态。方法2020年在全地区7个县、2个市的117个自来水厂及水厂所覆盖乡镇,采用随机数字表法进行城乡居民生活饮用水抽样,采用原子荧光法检测水砷含量,液相色谱原子荧光联用仪检测水砷形态。结果共采集626份水样,水砷含量<0.01 mg/L的水样614份,占98.08%;水砷含量0.01~<0.05 mg/L的水样12份,占1.92%;无水砷含量≥0.05 mg/L的水样。阿克苏地区超标水样水砷形态均为五价砷酸盐。阿瓦提县水砷含量最高(0.0046 mg/L)。结论新疆阿克苏地区仍存在部分水砷较高县市,存在饮水型地方性砷中毒(简称地砷病)的隐患,应改进净水处理工艺或改换水源,以有效防治地砷病。Objective The arsenic content of drinking water in Aksu Prefecture of Xinjiang Uygur Autonomous Region(referred to as Xinjiang)was analyzed to understand the distribution of arsenic content and arsenic form of water in each county and city.Methods In 2020,a total of 117 waterworks and villages(towns)under the jurisdiction of waterworks in 7 counties and 2 cities were randomly sampled,arsenic content in water was detected by atomic fluorescence spectrometry,and arsenic form in water was detected by liquid chromatography atomic fluorescence spectrometry.Results A total of 626 water samples were collected,614 water samples with water arsenic content<0.01 mg/L,accounting for 98.08%;12 water samples with water arsenic content 0.01-<0.05 mg/L,accounting for 1.92%;and there was no water sample with arsenic content≥0.05 mg/L.The form of arsenic in excessive water sample in Aksu Prefecture was found to be five-valent arsenate.The arsenic content in the water of Awati County was the highest(0.0046 mg/L).Conclusions There are still some counties and cities with high arsenic content in water in Aksu Prefecture,and there are still hidden dangers of drinking-water brone endemic arsenism.Therefore,the water treatment technology should be improved or the water sources should be changed to prevent endemic arsenism.
