摘要/Abstract

Abstract: Forest yellow soil and arable yellow soil in Jinyun Mountain were collected to study the effect of simulated acid rain(adjusted to pH 2.0,3.0,4.0 and 5.0) on the Hg leaching from soils by the methods of static extraction and dynamic leaching.The results showed that in forest yellow soils,surface accumulation of Hg occurred,and the accumulated Hg was easier to be leached out than that in arable yellow soil by acid rain.The amount of leached Hg was the largest at pH 4.0.To abate the risk of Hg pollution in water bodies by the Hg leaching from this forest soil,the Mountain should be closed,and timber-felling should be forbidden.

Key words: Simulated acid rain, Hg leaching, Static-state extraction, Dynamic-state leaching
