    Understanding the mechanism of Hg accumulation in soil which is a net Hg sink at a national scale is important for protecting the environment and improving food safety. The mercury (Hg) distribution in surface soil in China is quite uneven with relatively high concentrations in southeastern China and low concentrations in northwestern China. The reason for this distribution is inconclusive
