中文摘要: 为了解汞矿选冶采矿活动对当地生态环境的影响,以贵州某汞矿区尾矿堆场为研究对象,利用随机布点法采集土壤样品及农产品个60份,利用内梅罗综合指数法、潜在生态风险评价法对土壤重金属污染程度进行评价,利用健康风险评估模型对农产品中重金属的健康危害进行评估。结果表明,研究区土壤复合污染程度为重污染,Hg贡献最大,Cd次之,且A区较B区土壤污染严重。蔬菜、稻米、玉米中Hg的超标率分别为82.8%、46.7%、20%,蔬菜中Cd的超标率为51.7%,其他元素均低于限量标准。食用当地稻米及蔬菜对人群产生的健康危害指数HI>1,可能存在潜在健康风险,玉米对人群产生的健康危害指数较小,其潜在健康风险可忽略不计。土壤重金属含量与农产品中重金属含量无明显相关性。

Abstract:In order to investigate impact of mercury mining activity on local ecological environment, soil and agricultural products around mercury mining area in Guizhou, 60 soil samples and 60 agricultural products samples were collected by random sampling to evaluate pollution degree of heavy metals in soil by Nemerow comprehensive index method and potential ecological risk assessment method, and population""s exposure to heavy metals in agricultural products by health risk assessment model. The results show that pollution degree of soil in study area is heavy pollution; Hg shows the highest contribution factor in soil, followed by Cd, and soil pollution in Area A is more serious than that in Area B. Over standard rate of Hg in samples of vegetables, rice and corn is 82.8%, 46.7% and 20%, respectively, followed by 51.7% samples of Cd in vegetables, and other elements do not exceed limit standard in food. Health hazard index (HI>1) of rice and vegetables may have health risk, but corn is safe. There is no obvious linear relationship between heavy metal content in soil and edible part of agricultural products.
