A field study to investigate the air-soil mercury exchange was conducted outside the south end of Essex Hall, University of Windsor, Windsor, Ontario from February 10 to March 9, 2004. A higher average total gaseous mercury (TGM) concentration (5.9 ng/m3) was measured for this site than two rural sites during the same season of 2003. Local and regional anthropogenic sources are considered to be the cause. Overall, a 76.5% variation of mercury flux was explained by TGM concentration, soil temperature and total solar radiation. Disintegration of radiation and soil temperature effects was conducted in a controlled chamber study. The radiation was more correlated to the air-soil mercury flux than was the soil temperature. The type of light source seems to have an effect on the mercury flux. Ten models, eight from the chamber study and two from the field study, were developed.
