摘　　要：目的结合CoogleEarth建立村级饮水型地方性砷中毒地理信息数据库，为有效地防治和管理地方性砷中毒提供科学依据。方法2008年，选择内蒙古托克托县什力圪图村作为调查地区，现场采集该村所有饮用水水样，应用高效液相色谱一氢化物发生一原子荧光法测定水砷。应用全球定位系统（GPS）获取水源相关地理信息，在CoosleEarth中绘制并建立该村饮水型地方性砷中毒地理信息数据库。结果什力圪图村共有5处饮用水水源。分布在北纬40°29＂09-40°29＇36＂，东经111°28’00＂～111°29’02＂，海拔高度在1010-1021in。5处水源中，有4处水砷〉0．05mg／L，1处水砷〈0．05mg／L；1处已停用，其余4处分别为该村4个大队的居民提供13常饮用水。结论应用GoogleEarth建立的村级饮水型地方性砷中毒地理信息数据库可以真实、直观地反映病村的实际状况，为现场流行病学调查工作提供参考，同时也可以有效地防治和管理地方性砷中毒。Objective To construct geographic information database of drinking water type of endemic arsenism at village level with Google Earth and provide scientific basis for prevention and management of endemic arsenism. Mthods Drinking water samples were collected in the field of Shilegetu village, Tuoketuo county, Inner Mongolia in 2008. Arsenic concentrations were determined by high-performance liquid chromatography-hydride generation-atomic fluorescence spectrometry. Global positioning system（GPS） was performed to obtain the geographic information of the water sources. Google Earth was applied to establish the geographic information database. Results There were 5 drinking water resources in this village. They were located between 40o29＇09＂ N and 40~ 29＇ 36＂ N latitude and 111028＇00＂ E and 111o29＇02＂ E longitude, with the altitude between 1010 m and 1021 m. For all drinking water resources, four water arsenic concentrations was beyond 0.05 mg/L and one below 0.05 mg/L. In addition, one water source had been abandoned and the remaining four were providing daily drinking water for residents of the villages. Conclusions The geographic information database, established by Google Earth, can intuitively reflect the real situation of the endemic village. It can provide more useful information for field epidemiological research. It is an effectively tool in control and management of endemic arsenism.
