摘要(Abstract)：
通过实地调查以及土壤和水稻样品分析,研究了湘南郴州柿竹园铅锌矿、郴州界牌岭锡多金属矿、衡阳水口山有色金属矿、衡阳龙王山金矿4个矿区稻田的As污染状况.结果表明:4个矿区的稻田土壤和水稻植株均已受到严重的As污染.矿区稻田土壤As含量范围为30.0～225.7mg·kg-1,超过国家土壤环境质量3级标准;水稻根系、秸秆、谷壳、糙米As含量范围分别为115.6～588.2、4.19～20.88、1.388～5.374、0.214～0.892mg·kg-1,除部分糙米样品外,均超过我国食品中As限量卫生标准.矿区稻田土壤同时受到As和重金属的复合污染,综合污染指数(P)范围为0.76～13.12.矿区稻田的As污染主要由矿产的开采和冶炼造成,其中,水口山有色金属矿区和龙王山金矿区As污染以及As和重金属复合污染最为严重,柿竹园铅锌矿区污染面积较大,界牌岭锡多金属矿区由于发生过地质灾害改变了地表面貌,污染情况更为复杂.
