摘　　要：通过实地调查以及采集土壤和植株样品分析,研究了湖南省郴州柿竹园、石门雄黄矿、冷水江锡矿山这3个矿区的As污染状况。结果表明,3个矿区的农业生产都受到了As污染的影响,都出现过As中毒的事故,采集的土壤和植物样品As含量范围分别为18.9～7097.5mg·kg-1和8.4～1538.2mg·kg-1。3个矿区的As污染都是由矿产开发和冶炼所造成的,其中,柿竹园矿区污染最严重,柿竹园和锡矿山污染面积较大,且都为As与其他重金属的复合污染,污染状况较为复杂。A field survey and analysis of soils and plants sample were conducted to investigate arsenic-polluted conditions of 3 mining areas, which were Shizhuyuan （Chenzhou）, Realgar mine （Shimen）, and Xikuangshan （Lengshuijiang）, in Hunan. The results showed that, in the past decades, agricultural productions were interfered and there occurred some pollution accidents in these 3 mining areas. Moreover, arsenic contents in soils and plants collected were 18.9-7 097.5 mg·kg^-1 and 8.4-1 538.2 mg·kg^-1, respectively. In these 3 mining areas, all arsenic pollution resulted from exploitation and smelt of mineral resources. Pollution of Shizhuyuan mining area was the most serious in these 3 areas, and, in Shizhuyuan mining area and Xikuangshan mining area, complex pollution of arsenic and other heavy metals was discover and polluted areas were bigger than that in Realgar mining area.
