摘要: 我国饮水型砷中毒的流行屡见报道,台湾嘉南、新疆奎屯、内蒙古河套及山西大同等地是我国几个有代表性的病区。病区多为河湖相和滨海相沉积,粘土、粘土质淤泥和有机淤泥层发育,为富含有机质的还原环境,地下水中砷的含量一般为0.2~0.6mg/L.有时还有氟、腐殖酸、甲基胂酸和某些烷烃类等的有害有机化合物。砷中毒主要与总砷、As3+和甲基胂酸等有关。除砷中毒外,往往还有地氟病和癌症流行。由于各病区地下水化学成份的差异,不仅砷中毒的危险浓度不同,而且砷中毒的类型也不同,文章将病区环境划分为三种地质环境类型。

Abstract: There are many reports about endemic arseniasis in China. Jianan in Taiwan, Kuitun in Xinjiang, Hetao area in Inner Mongolia and Datong in Shanxi are four typical arseniasis areas. The arseniasis areas are mostly deposits of river and limnetic facies or marine bed with clay, clayey and organic mud, and belong to environment with rich organic matter. Arsenic in groundwater is 0.2-0.6 mg/L and some harmful organic materials, such as fluorine, humic acid, methyl arsenate and hydrocarbon. Arseniasis related mainly to total arsenic, As3+ and methyl arsenate. Besides arseniasis, there are fluorosis and cancer in these areas. Because of the difference of chemical compounds in ground water, there are different "dangerous concentration" and arseniasis types. Three geological environmental types are classified. The paper not only summarize the characteristics of geological environment but also provides important basis for prevention, cure and research of arseniasis.
