摘要
Abstract
[Objective] The research aimed to study the heavy metal pollution status in farmland soil of suburb in Longjing City, Jilin Province. [Method] The heavy metals (Cu,Zn,Pb and Cd) contents in farmland soil of Longchi village, Longjing City were evaluated based on the second grade of national soil environmental quality standard (GB15618 - 1995). Single factor pollution index and Nemerow integrated index were applied for the evaluation. [ Result ] The single factor index was in order of Cd > Zn > Cu > Pb. Cd was found to be a major heavy metal contaminant in the soil. For the different farming types of dry land and paddy land, the integrated pollution index was 1.34 and 1.66 respectively. Both farming types were found to be above warning range and the pollution rankings were light. The paddy land was polluted more severely. [Conclusion] The integrated pollution index in the farmland of suburb in Longjing City was 1.57 and the pollution ranking was light.关键词
