Abstract

The concentration levels of n-alkanes and water soluble organic carbon (WSOC) at Anmyon, a Global Atmospheric Watch (GAW) station operated by Korea Meteorological Administration (KMA), has been characterized for the PM10 samples collected in 2010. It was found that the concentrations of WSOC at Anmyon were comparable to those in Seoul and lower than those in Gosan, another background area in Korea. However, the maximum concentration of the WSOC at Anmyon was observed in fall while that at Seoul was in winter. It suggests that the emission and/or transformation characteristics at two areas are different. The concentrations of n-alkanes at Anmyon were slightly lower than at Gosan and about one thirds at Seoul. However, it was found that at Gosan the n-alkanes from natural sources were dominant at Gosan. On the other hand, n-alkanes from anthropogenic sources were dominant at Anmyon. Study directions to further understand the characteristics of aerosols at Anmyon are discussed.

우리나라의 대표적인 배경지역 측정소인 안면도의 지구배경관측소에서 20010년에 채취한 미세먼지(PM10) 시료에 대해 n-alkane과 수용성 유기성분(WSOC) 농도를 분석하였다. 우리나라의 또 다른 배경지역인 고산에 비해 봄철의 수용성 유기성분의 농도는 세배 정도 높았다. 안면관측소의 수용성 유기성분의 농도는 서울이나 아시아 다른 도시지역의 농도와 비슷한 수준이었다. 그러나 아시아 도시는 겨울에 농도가 높았으나, 안면관측소는 가을에 높아 배출원, 또는 생성원이 다른 것으로 보인다. 한편 n-alkane 성분의 농도는 안면관측소가 고산보다 약간 낮았고, 서울 등의 아시아 도시의 1/3-1/2 수준으로 낮았다. 그러나 고산은 자연적인 기원의 n-alkane 농도가 높은 반면에 안면관측소는 인위적인 n-alkane이 대부분이어서 대조를 보이고 있다. 따라서 안면관측소는 우리나라의 대표적인 배경지역임에도 불구하고 수용성 유기성분과 n-alkanes 농도측면에서는 배경지역과 도시지역의 특성을 갖고 있어, 인위적인 영향을 많이 받고 있는 것으로 보인다. 보다 상세한 배출원과 생성원 분석은 무기이온농도와 다른 유기성분 분석을 추가하여 이루어질 예정이다.
