As part of our continuous efforts to elucidate the behavior of total gaseous Hg at strong source area, we conducted micrometeorological measurements of its fluxes from Nan-Ji-Do (NJD) landfill site during the fall period of 2001. Results of our study confirmed that emission of Hg is overwhelmingly dominant over its dry deposition in its frequency; however, its deposition is found to be large in magnitude relative to emission event. The mean fluxes of Hg across soil-air interface of NJD, when computed using the concentration gradients and relevant parameters, were found at 576+436 (during emission: N=142) and -930+1065 ng/m2/h (during dry deposition: N=37). The occurrences of abnormalously high exchange rates were mainly due to the combined effects of enormously high gradient values and high transfer coefficients at elevated site. The overall results of our study thus suggested that the site should serve as net source of Hg with emission strength of 6.4 μg/m2/day.
