摘要
对某燃煤电厂废弃灰场土壤中的Cr、Hg、As、Cu、Pb、Cd、Zn、Ni等重金属进行测定分析,并以国家二级质量标准为评价标准来评价其环境质量状况。结果表明:该灰场土壤中Hg、Pb、Zn为非污染水平,As为轻污染水平,Cr为中污染水平,Cu、Cd、Ni为重污染水平,该地块综合污染指数为24.69,达到重污染程度。
Cr, Hg, As, Cu, Pb, Cd, Zn, Ni in the waste ash field of a coal-fired power plant were measured and analyzed.Furthermore,the pollution assessment of the heavy metals from the soil was based on the single factor index and Nemerow comprehensive index according to environmental quality Standard for Soil of China(2nd level).The analytic results revealed that Hg, Pb, Zn were not polluted, As was slight polluted, Cr was polluted, Cu, Cd, Ni were heavy polluted in the soil. The comprehensive pollution index was 24.69, reached heavy pollution level.
