In this article, 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 impact of construction waste.Abstract:
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 impact 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 content 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.read more
