Abstract
Mercury is con仕nuously emitted from both natu� ral and anthropogenic sources. After releasing to atmosphere, it affects the environment such as oxidized, deposition, and long distance transportation. Mercury is a potent threat to the environment or human health. Exposure route of mercury has direct exposure and indirect ex� posure through bioaccumulation. Major anthro� pogenic sources in Korea are coal-fired power plants, production of non-ferrous metals, waste incinera仕on facilities, and cement clinker pro� duction facilities. Atmospheric mercury concen� tration near the sources is known that higher than other regions, which is likely to potentially have an impact on the health of local residents.

Therefore, it is necessary to investigate the types and chemical properties of mercury con� centration in the atmosphere. This study meas� ured the atmospheric mercury concentrations near major emission facilities in Korea and tried to estimate the human risk. Background concen� trations of TGM, RGM and Hg-p were 1.52ng/m3, 8.35 pg/m3 and 13.30 pg/m3 during the summer period. During the winter period, aver� age concentrations of TGM, RGM and Hg-p were 1.61 ng/m3, 5.57 pg/m3 and 21.09 pg/m3, respectively. The average concentration of major sources sites in the summer was 2.29 ng/m3, 21.12 ng/m3 and 46.07 pg/m3. During the winter period, average concentrations of TGM, environment or human health.
