摘要
目的了解山西省地方性砷中毒病区改水降砷落实情况，为砷中毒的防治工作提供科学依据。方法2011年6月，采用调查问卷的方式，在山西省的151个砷中毒病区村调查改水降砷工程使用和运转情况。在病区村采集改水工程水样，水砷测定采用原子荧光法。结果在151个砷中毒病区村，有126个已经改水，改水率为83．44％；在已改水的病区村中，有22个村不能正常使用。覆盖全省砷中毒病区村的改水降砷工程有33个，正常运行的有23个；正常运行的改水降砷工程覆盖砷中毒病区村110个，受益人口为97920人，占病区村总人口的46．9％（97920／208736）。改水工程水含砷超过国家标准（≤0．05mg／L）的有10个，覆盖31个村，包括15个非病区村和16个病区村，覆盖病区村人口数为24764人。结论山西省的地方性砷中毒病区改水力度有待加强，改水工程质量需要提高，工程的后期管理和维护还需要进一步加强。
Objective To investigate the actual situation of implementation of the project to reduce water arsenic in endemic arsenic poisoning areas in Shanxi province, and to provide a scientific basis for prevention and control of the disease. Methods In June 2011, a questionnaire survey of 151 arsenic endemic villages was carried out in Shanxi province. The actual situation of implementation of the project to reduce water arsenic was investigated. Water samples were collected and arsenic level was determined by atomic fluorescence spectrometry. Results In the 151 arsenic poisoning villages 126 villages had changed the water, and the rate was 83.44%. In these villages, 22 villages did not use the water improvement utilities properly. Of the 33 water improvement projects to reduce arsenic, 23 operated normally. The projects covered 110 villages, beneficiary population of 97 920 people, accounting for 46.9%（97 920/208 736） of the total population. Water arsenic exceeded the national standards（ ~〈0.05 rag/L） in 10 of the water improvement projects which covered 31 villages, including 15 non- endemic villages and 16 diseased villages. There were a population of 24 764 people in the diseased villages. Conclusions In Shanxi endemic arsenic poisoning areas, water improvement efforts need to be strengthened; the quality of water improvement project needs to be improved, and the project＇s later management and maintenance also need to be further strengthened.
