摘要
本文针对吉林省 5个主要大豆种植区重金属分析测试结果 ,选取国家颁布的《土壤环境质量标准》 (GB15 6 18- 95 )为评价标准 ,进行了重金属污染评价 ,其结果为 :只有敦化种植区铜、镍和桦甸种植区铜含量超标 ,并且为轻度污染。其它地区重金属污染指数 (Pi)小于1。
According to the contents of heavy metal in soil sampled from five main soybean croplands in Jilin province,the article assesses the level of heavy metal pollution in soil according to "the quality standard of soil environment"(GB 15618-95)issued by China The analysis result indicates that the contents of copper and nickel in the Dunhua's soybean cropland and the contents of copper in Huadian's cropland exceed the criteria,but the pollution is not much The index of heavy metal pollution in soil in other area is less than 1,or soil almost was n't polluted by heavy metal
