摘要
对聊城市十五里元镇高产粮田100个土壤样品中铜、锌、铅、镉含量进行分析测定,参考国家土壤环境质量标准(GB15618-1995),采用单因子污染指数法和内梅罗综合污染指数法对土壤环境质量进行了评价。研究结果表明,十五里元镇高产粮田土壤综合污染指数为1.161,处于轻度污染状态;4种重金属元素的单项污染指数均未超标,但镉污染达到警戒级。
Contents of heavy metals (Cu,Zn,Pb and Cd) in soils of grain area in the northwest of Shandong Province were investigated in order to evaluate environmental quality of heavy metals. The contamination status of above-mentioned soils was assessed by means of single and Nemerow Synthetical pollution index method comparing with the environmental quality standard for soils of China. The results showed that soils of grain area in the northwest of Shandong Province were low-grade polluted. The Nemerow Synthetical pollution index was 1.161.The single pollution indexes of Cu, Zn, Pb and Cd were not exceeded the quality standard, but the single pollution index of Cd was watchful.
