Abstract：The mercury fluxes between soil-air interfaces in 5 lawns of Guangzhou City were monitored by using a dynamic flux chamber coupled with a Tekran 2537A Ambient Mercury Vapor Analyzer. The average value of the mercury fluxes between soil-air interfaces in 5 monitoring points was 7.341±9.714 ng·m-2·h-1. The effects of environmental factors on the mercury fluxes were examined. The soil mercury concentration affected the releasing capability of Hg in soils. The mercury exchange fluxes showed significant positive correlations with total solar radiation intensity and soil temperature and significant negative correlations with the pH values. It was also found that the rainfall and vegetation significantly affected the mercury fluxes.
