摘　　要：目的了解陕西省高砷水源的分布情况，为下一步采取有效措施，减轻砷中毒对暴露人群的危害提供理论依据。方法采用普查和抽样调查相结合的方法。对陕西省黄河沿岸和陕南重金属矿区12个县（市）1898个自然村的4042个水源进行调查，统一采用水砷快速检测试剂盒半定量检测饮水中含砷量，对于重点调查的山阳县水砷采用原子荧光光度法进行定量检测。结果水源超标的自然村2个；超标水源6个，均在山阳县，含砷量分别为0．46、0．53、0．63、0．69、0．74、1．53mg／L，超标率为0．15％（6／4042）；高砷水暴露人口数为1146人，其中暴露儿童人数为555人。结论陕西省山阳县存在饮用水含砷量超标的情况，暴露人群数量较多，应尽快改水降砷，减轻高砷危害。Objective To explore the distribution of high-arsenic water in Shaanxi Province in order to provide theoretical basis for the control of arsenism. Methods The contents of arsenic of 4042 water sampled from 1898 nature villages in 12 counties were assessed using semi-quantitative reagent-knit, and the water samples of Shanyang County, the targeted area, was quantified using quantitative atomic fluorescent specmetry. Results The contents of arsenic of 6 water samples in 2 villages exceeded 0.05 mg/L, accounting for 0.15%（6/4042）, were 0.46, 053,0.63,0.69,0.74,1.53 mg/L, respestively, and located in Shanyang County. A crowd of 1146 exposed to high asenic water, among whom 555 were children. Conclusions Arsenic in drink water in Shanyang County in Shaanxi Province is higher than the standard, to which a large number of people are exposed, water-improving and defluoridotion must be carried out as soon as possible, reduces harm of high arsenic.
