Abstract：Objective To explore the distribution of high arsenic-containing drinking water source in key area of Yunnan province and provide scientific evidence for investigating the prevalence of Water-type endemic arsenicosis. Methods The water arsenic was screened with half quantitative method of fast test？？kit. The samples with level of arsenic over 0.03mg/L were analyzed quantitatively. ArcGIS 10.2 was used for drawing thematic maps based on Yunnan vector maps. Results Out of the 8585 villages from 35 counties， 45 villages from 11 counties were found to have high arsenic-containing drinking water sources. Conclusion There are 45 villages from 11 counties in 3 prefectures to have high arsenic-containing drinking water source ......
