作者： WANG Ding yong, LIU De shao, YAO Ai jun, PI Guang jie, MOU Shu sen, QING Chang le (College of Resources and Environment, Southwest agricultural University, Chongqing 400716, China)

The results from investigations indicated that mercury pollution in terrestrial ecosystem was serious due to the anthropogenic mercury emission growing in Chongqing, China. The concentration of atmospheric mercury in Chongqing was 34.4±2.7 ng/m\+3 with the range of 9.2—101.5. The accumulation of mercury in surface soil was increasing with time. The mercury content of some agricultural products have exceeded the food health standard value, especially near the mercury emission sources. The mercury accumulation in soil plant system was affected by atmospheric mercury and a positive correlation between them was found. Volatilization of mercury was the most important processes with which soil mercury joined the global mercury recycling.
