摘    要:为了研究水头制革污染区域土壤和稻米重金属污染状况,采集该区城农田土壤、稻米样品,测定重金属As、Hg、Pb、Cr、Cd含量。结果表明:农田土壤重金属的平均含量分别为As6.1mg·kg^-1、Hg0.15mg·kg^-1、Pb51.3mg·kg^-1、Cr77mg·kg^-1、Cd0.32rag·kg^-1,其中Cd超过国家二级标准的6%,土壤已经受到了重金属的污染。以国家食品卫生标准中规定的重金属限量为标准:稻米cd含量部分超标,超标率为60%。土壤和稻米中的Cd含量相关性显著。

关 键 词:农田土壤污染  重金属  污染指数  评价  水头镇

Abstract:The heavy metal pollution from leather industry area in the soil and rice is investigated by sampling the soil and rice to detect the contents of As and Hg and Pb and Cr and Cd respectively. The results disclose that the average contents of As and Hg and Pb and Cr and Cd in the soil are 6. lmg/kg, 0. 15mg/kg, 51.3mg/kg, 77mg/ kg and 0. 32mg/kg respectively, among which, the content of Cd is 6% more than that of national second grade standard and the soil has been polluted already. Similarly, the content of Cd in the rice is 30% larger than that national standard. The content of Cd in soil has a significant relation with Cd in the rice.
Keywords:soil pollution  heavy metal  pollution index  assessment
