类金属砷(As)及其化合物被世界卫生组织国际癌症研究机构列为一类致癌物。As具有亲煤特性，煤层作为As的重要载体，因煤炭开采导致类金属砷(As)对矿区周边土壤的污染及其修复是值得关注的课题。本文对目前国内外学者对煤矿区环境介质中不同形态As的来源、分布、迁移转化等进行解析，为创新探索研究方向，控制污染物来源，限制传播途径、制定环保策略等提供重要依据。 Arsenic was a kind of metal element. Arsenic and its compounds were listed as a kind of carcino-gen by the International Cancer Research Institute of the World Health Organization. Because the coal affinity of As, coal seam was an important carrier. The pollution of arsenic (As) to the soil around the mining area caused by coal mining and its remediation was a subject worthy of attention. This paper analyzes the source, distribution, migration and transformation of different forms of As in the environmental media of coal mining area by domestic and foreign scholars, which provided an important basis for innovating and exploring the research direction, controlling the source of pollutants, limiting the transmission path, and formulating environmental protection strategies.
