以成都某生活垃圾焚烧厂为例，通过实验分别研究了焚烧产物中各主要重金属的含量和浸出毒性，由此分析了生活垃圾焚烧产物中的重金属对城市环境的危害。结果表明，该生活垃圾焚烧厂排放的飞灰和炉渣样品中，镉，铜，铅，锌的含量接近或超过国家土壤环境质量标准三级标准，其浸出液pH呈强碱性，镉和飞灰中铅量超过国家浸出液中危害成分浓度限值标准，在环境中存在潜在危害性。在此基础上探讨了生活垃圾中重金属的来源，提出了可行性建议。

Taking a waste incineration plant of Chengdu for example, this study researched the total amount and leaching toxicity of the major heavy metals in burning products, respectively in order to analyze the harmful effects of these heavy metals to the environment during the incineration of domestic wastes. The results show that the content of Cd, Cu, Pb, Zn in tly ash and slag is close or exceed the National Soil Environmental Quality Standard Grade Ⅲ. The leaching solution pH is strongly alkaline. The Cd and Pb in the fly ash have exceed national leachate concentration limit for hazardous constituents, the existence of which has potential hazards to the environment. On this basis, the sources of these heavy metals in domestic wastes are discussed and the feasible proposals are also proposed.
