使用X射线荧光光谱法对建筑垃圾样品中As、Pb、Hg、Cr、Cd、Cu、Zn7种重金属元素含量进行分析，为进一步研究建筑垃圾对环境的影响提供一定的科学数据。根据含量结果统计分析发现，不同种类建筑垃圾中重金属元素的含量差异明显，同一种类不同来源建筑垃圾的重金属含量也有区别。对于所分析的建筑垃圾样品，均有重金属含量超过成都大平原土壤背景值，甚至有的重金属含量超过了土壤环境质量标准和城镇垃圾农用控制标准，表现出不同程度的潜在环境风险，其中尤以样品中Hg元素的潜在环境风险最为突出。

The contents of As, Pb, Hg, Cr, Cd, Cu and Zn in the construction waste are determined by X -ray fluorescence spectrometry , it provides an amount of scientific data for the further study on the environmental im -pact of construction waste .According to the statistical analysis , there are obvious differences about heavy metal contents in the different materials of construction waste .Even in the same material, the heavy metal contents of construction waste from different place are different .For analyzed samples, there is part of the heavy metal con-tent of more than the soil background values?? of Chengdu Great Plains, and even some heavy metal content than environmental quality standard for soils and control standards for urban wastes for agricultural use , show varying degrees of potential environmental risk , especially Hg.
