Soil samples collected from five localities in different areas (the high-mercury area, the man-made mercury-polluted area and the reference area) were analyzed for the seven mercury species. It is found that high mercury contents of soils can be attributed to both man-made Pollution and geological processes, but the two kinds of soils show obvious differences in the distribution of their mercury species.展开更多
