Report of Screening of Water Arsenic and Investigation of Endemic Arsenism in Huhhot

Objective：To investigate the epidemical scope of the endemic arsenism and provide a scientific evidence for control and prevention.Methods： The surveillance was carried out according to the demand of ＂National investigate scheme of endemic arsenicosis＂.The arsenic content of drinking water was determined by DDC-Ag.Patients of endemic arsenism were diagnosed by ＂Endemic arsenism area dividing standard and clinical diagnosis interim rule＂ and ＂Standard of diagnosis for endemic arsenism＂.Results： There were 14.19% arsenic content beyond national standard among 909 villages.There were 13.86% arsenic content in drinking water improving project beyond national standard.The disease census indicated that the prevalence rate is 14.17% from 51 endemic arsenism villages.Most of endemic arsenism degrees were suspicious and light patients.The disease was mostly occurred in those aged over 40 years.There was significant difference of gender between males and females（P0.01）.Conclusion： Most of the endemic arsenism areas are mild and moderate arsenic districts.
