摘要
目的 掌握山西省地方性砷中毒病区分布范围和病情流行状况 ,为今后病区防治提供科学依据。方法 对所有饮水超标的村屯进行整群普查。结果 1调查发现饮水高砷区覆盖 7个县区的 147个村屯 ,超标饮水井 80 5个 ,最高饮水砷含量达 4.43mg/ L,超过国家饮水标准的 88倍 ;2查出病人 5 6 0 4例 ,其中轻度病人 42 2 0例 ,中度病人 913例 ,重度病人 471例 ,查出癌症病人 35 8例。患病最小年龄 7岁 ,最大年龄 80岁以上 ;3确定病区村屯 78个 ,其中轻病区 46个 ,中病区 2 1个 ,重病区 11个。结论 饮水砷高是引起该病发生的主要原因 ,水砷高又属于天然形成 ,因此 。
Objective To find out the distribution areas and prevalent situation of endemic aresenism in Shanxi,provide academic evidence for further prevention and treatment of endemic arsenism.Methods The cluster sampling was carried out for all villages where the arsenic content in water exceeded the hygiene arsenic criteria of drinking water.Results The investigation result showed that ①The areas of high arsenic water covered 147 villages belong to 7 counties.805 wells had superstandard arsenic.The highest arsenic content was 4.43 mg/L ,which is 88 times of national hygiene arsenic criteria of drinking water.②5 604 patients were discovered.Among them,4 220 cases were light,913 were moderate,471 were severe.The 358 of cancer cases were also found.The youngest patient was 7 years,and the eldest one was over 80 years.③78 villages were determined to epidemic regions of endemic arsenism.There were 46 of light regions,21 moderate,11 severe.Conclusions The high arsenic content in drinking water is the main reason induced endemic arsenism.But it is formed by nature,so those epidemic areas should be classified to endemic arsenism by drinking water.
