Investigation of soil mineral component in the Baikal Region by X-ray electron probe microanalysis

The procedure of X-ray electron probe microanalysis (EPMA) has been developed for the investigation of soil mineral component. In terms of reproducibility and accuracy, the suggested EPMA procedure satisfies the requirements of analysis of the second category. The phase and chemical composition of soil mineral component were investigated by X-ray electron probe microanalysis with the aim of environmental pollution estimation in Lake Baikal Region. The investigations of soil mineral component by EPMA from regions with various man-caused loading degrees allow identification of basic pollution sources and their influence on the environment and estimation of anthropogenic accumulation in clear background regions and regions with high man-caused loading degree.
