摘要：PM10 and PM2.5 in ambient air were collected in Seongbuk-gu area of Seoul for one year,from April 2005 to February 2006,and the concentration of PM-bound mercury was monitored. The annual concentrations of particles were 66.4±43.2 µg/m3 (47.6±19.1 µg/m3 ~106.1±78.0 µg/m3 ) in PM10 and 37.2±20.4 µg/m3 (28.0±23.4 µg/m3 ~42.7±21.4 µg/m3 ) in PM2.5,which is about 56% of PM10 concentration. The annual average concentrations of mercury were 0.125±0.078 ng/m3 in PM10 and 0.141 ±0.080 ng/m3 in PM2.5,respectively. In April of Asian dust season in Korea,mercury showed the highest concentration in both PM10 and PM2.5.
