摘要
通过对贵州省遵义市郊12个主要菜区土壤中重金属(As、Pb、Cd、Cr、Hg)含量的调查和分析测定,采用模糊评价法对土壤重金属污染状况进行评价。结果表明该地区综合评定污染等级为尚清洁,其评价结果与内梅罗综合污染指数评价的结果一致,而本方法直观性更强。污染等级为尚清洁,说明人为的活动已经影响到土壤的质量,应予以重视并加以控制。
The contents of five heavy metals-As, Pb, Cd, Cr and Hg-in twelve soil samples taken from main vegetable cultivating area in Zunyi suburb were investigated. The contamination degree of these soils were evaluated by using fuzzy comprehensive assessment. It was found that the pollution degree of the investigated soil were hypo-cleanliness, which indicated that the quality of the soil had been affected by human being. The result was also in accordance with the result by using Nemerow comprehensive assessment.
