　　以山东矿区某两个电厂燃煤为例，探讨了燃煤产物中重金属元素的环境影响评价方法。测定了电厂原煤、飞灰、底灰中As、Cu、Zn、Pb这4种重金属元素的含量，通过浸泡实验测得了燃煤产物中重金属元素的浸溶率，计算出了燃煤产物中重金属元素对大气、水环境的污染因子。结果表明，电厂燃煤过程中，重金属元素挥发性较高，两电厂对大气环境的综合污染因子分别为6．83和7．93，污染等级为重污染。对于水环境的综合污染因子为4．35与3．38，也属重污染。

Taking coal combustion products from two coal -fired power plants in Shandong as example , the envi-ronmental impact assessment method of heavy metals in coal combustion products was studied .4 heavy metals of As, Cu, Zn, Pb, Hg in raw coal, fly ash,bottom ash of the power plants were determined .The leaching rate of heavy metals in the coal combustion products were determined by immersion test .Atmospheric pollution index, water pollution index were calculated .The results showed that the volatility of the heavy metals in the coal during coal combustion is high.The integrated pollution indices of the heavy metals in the coal from the two plants to at-mospheric environment are 6.83 and 7.93, which belong to heavy pollution indices.The integrated pollution in-dices of heavy metals in the coal -fired products to water environment are 4.35 and 3.38 respectively, belonging to heavy pollution indeces.
