Natural attenuation of copper toxicity in soils and soil constituents: a synchrotron and isotopic investigation

摘要：

Natural attenuation or aging is known to have a significant effect on the availability and toxicity of soil contaminants. Here we employed x-ray absorption spectroscopy and isotopic dilution techniques to examine the Cu aging mechanisms in soils and soil constituents. Both these techniques suggested that there were differences in Cu attenuation between the studied soils and soil constituents. The aging mechanisms appeared to be related to the different characteristics of the sorbing materials.
