自然界中单质砷少见，大多数以硫化物的形式存在于岩石和砷矿中。地方性砷中毒是一种生物地球化学性疾病，对人类健康损害极大，因此，对砷中毒的研究日益受到人们的重视。笔者根据河套地区多目标区域地球化学调查资料，全面分析As在不同介质中的分布特征，圈定出河套地区砷中毒区的范围，对河套地区砷的地球化学分布特征及分布规律进行总结评价。从As在各种来源物质中的含量特征分析，最终得出结论，河套地区富含As的来源物质主要是黄河冲洪积物。

Arsenic is mostly present in rocks and arsenic ores in the form of sulfides rather than in the nature element form. Arsenic poisoning is a biogeochemical disease which poses a great threat to human health. As a result, there has been a growing emphasis on the study of arsenic poisoning. This paper is based on multi?target geochemical survey of the Hetao area and delineates the range of the ar?senic poisoning in the Hetao area with a comprehensive analysis of the distribution of arsenic in different media. In addition, this paper summarizes and evaluates the geochemical distribution of arsenic in the Hetao area. Based on the analysis of arsenic content in various sources, the authors have reached the conclusion that the main source of arsenic?rich substance in the Hetao area is the Yellow River alluvial matter.
