Abstract

본 연구에서는 2006년부터 2008년까지 3년간 봄철에 <TEX>$PM_{10}$</TEX>과 <TEX>$PM_{2.5}$</TEX>를 채취하여 질량농도와 금속원소의 화학적 특성, 기상인자와의 관계 분석, 황사 및 비황사시의 미세먼지 특성 그리고 이동경로에 따른 농도의 특성을 고찰하였다. 연구기간동안의 <TEX>$PM_{10}$</TEX>, <TEX>$PM_{2.5}$</TEX>, <TEX>$PM_{10-2.5}$</TEX>평균농도는 각각 <TEX>$126.2{\pm}89.8$</TEX>, <TEX>$85.5{\pm}41.6$</TEX>, <TEX>$40.7{\pm}54.9{\mu}g/m^3$</TEX>이었으며 <TEX>$PM_{2.5}/PM_{10}$</TEX> 및 <TEX>$PM_{10-2.5}/PM_{2.5}$</TEX> 비는 각각 0.70, 0.48이었다. 우리나라의 북서쪽인 북경을 포함한 지역과 서쪽인 상해를 포함한 지역에서 공기덩어리가 이류 할 때 가장 높은 미세먼지농도를 나타내었다. Twenty-four hour integrated <TEX>$PM_{10}$</TEX> and <TEX>$PM_{2.5}$</TEX> samples were measured during springtime (March, April, and May) in Busan for three years from 2006 to 2008, and mass concentrations and metallic elements of measurement were analyzed to investigate temporal, spatial, chemical characteristics of the mass concentration and metallic elements in association with meteorological conditions including Asian Dust (AD) vs. non Asian Dust (NAD) seasons, and other air mass transport patterns. The result showed that <TEX>$PM_{10}$</TEX>, <TEX>$PM_{2.5}$</TEX> and <TEX>$PM_{10-2.5}$</TEX> concentrations were on average of <TEX>$126.2{\pm}89.8$</TEX>, <TEX>$85.5{\pm}41.6$</TEX>, and <TEX>$40.7{\pm}54.9{\mu}g/m^3$</TEX>, respectively, and the <TEX>$PM_{2.5}/PM_{10}$</TEX> and <TEX>$PM_{10-2.5}/PM_{2.5}$</TEX> ratios were 0.70 and 0.48, respectively. The highest concentrations of PM were observed when air parcels were originated from both northwest sector covering Beijing and west sector including Shanghai areas.
