The level and distribution status of mercury in some soils of the Tropics and South-subtropics in China were described in this paper. The results obtained may be summarized as follows.1.The distribution frequency of mercury content in the soils studied is a lognomal one.The geometric mean is a value of 100 ppb,2.The accumulation of mercury was observed in the topsoil and the content of mercury decreases with the depth of the profile. The level of mercury in underlying igneous rocks is lower than that of each soil sample derived from them.3.The mercury content of these soils increases with the content of organic matter.4.All of the topsoils contain a little methylmercury, the level relates to the content of the total mercury in sample.5.The contents of mercury in the landscapes of geochemistry are as follows: The soil derived from superagual landscape>eluvial landscape>tran-seluvial landscape.
