摘要: 为系统了解武汉市黄陂区典型农田土壤重金属的污染水平及生态风险,采集并分析了364个代表性农田土壤表层样品中的8种重金属元素(As、Cd、Cr、Cu、Ni、Pb、Zn、Hg),采用单因子污染指数和内梅罗综合污染指数评价该地区土壤农田重金属污染状况。结果表明,黄陂区农田土壤90%以上处于清洁水平,存在的污染主要为Cd污染,7.69%的农田土壤处于Cd污染状态,3.02%以下的农田土壤处于Cu和Ni的污染状态,未发现农田土壤受到As、Cr、Pb、Hg和Zn的污染。

Abstract: Eight heavy metal elements (As,Cd,Cr,Cu,Ni,Pb,Zn,Hg) from 364 representative farmland soil surface samples were collected and analyzed in order to systematically understand the pollution level and ecological risk of heavy metals in the typical farmland soil in Huangpi district of Wuhan city. The single factor pollution index and Nemero comprehensive pollution index were used to evaluate the heavy metal pollution status of the farmland soil in this area. The results showed that more than 90% of the farmland soil in the area was in a clean level, and the main pollution was Cd pollution. 7.69% of the farmland soil was in the Cd pollution state, and less than 3.02% of the farmland soil was in the Cu and Ni pollution state. It was not found that the farmland soil was polluted by As, Cr, Pb, Hg and Zn elements.

Key words: farmland soils, heavy metal, pollution assessment, suburb area of Wuhan city
