Abstract

Particulate matters(less than 10㎛, PM10) at Kanghwa and Yangyang, which are located in the western and the eastern coastal regions in Korea, were measured in using low volume air sampler from December 1995 to November 1996, and their characteristics were investigated from the view point of background level.(and in order to characterize the particulate matters.) The particulate matters were analyzed for major water soluble ionic components(SO_4^2-, NO_3^-, Cl, Na^+, NH_4^+, K^+, Mg^2+ and Ca^2+) by ion chromatography. Mass concentrations of particulate matters were 48.77±22.45 ㎍/㎥ at Kanghwa and 54.04±32.98 ㎍/㎥ at Yangyang and SO_4^2-, NO_3^- and NH_4^+ contributed largely to water soluble ionic components. nss(non sea salt)-SO_4^2- contributed more than 95 percentage to SO_4^2-, and nss-K^+ and nss-Ca^2+ also contributed high percentages to K^+ and Ca^2+. It was supposed that most SO_4^2- was originated from anthropogenic sources, and K^+ and Ca^+ were mainly originated from soil. The results of factor analysis suggested possibility of interpreting the correlation between air pollutants and regional characteristics.
