| Abstract: | Taking South Lake and Jingyue Pool in Changchun as examples, we determined particulate Hg in ambient air and Hg concentration
in precipitation. Results indicated that particulate Hg in air and Hg concentration in precipitation in both sites in nonheating
period were lower than that in heating period, which is influenced by coal combustion. The annual particulate Hg concentrations
of South Lake and Jingyue Pool were 0.254ng/m3 and 0. 109ng/m3. The yearly average Hg concentrations in precipitation were 0.268μg/L(South Lake) and 0.108μg/L(Jingyue Pool). The higher
particulate Hg concentration in air and Hg concentration in precipitation in South Lake than that of Jingyue Pool indicated
that mercury deposition was influenced by anthropogenic sources (especially from coas combustion). Hg concentration in precipitation
is related with particulate Hg in the atmosphere. Dry deposition fluxes were estimated by using dry deposition model on the
base of particulate Hg concentrations in the atmosphere, they were 35.5μg/(m2. a) for South lake and 15.3μg/(m2. a) for Jingyue Pool. Combined with precipitation amount, wet deposition fluxes were estimated in these two sites, 152.2μg/(m2. a) for South Lake and 6.1.2μg/(m2. a) for Jingyue Pool. Atmospheric Hg deposition fluxes were 160.2g/a for South Lake and 328.62g/a for Jingyue Pool.
