최근 미세먼지가 사회적 재난으로 간주될 만큼 국민건강에 심각하게 영향을 끼쳐 사회문제가 되고 있다. 미세먼지의 주요 배출원인 대기배출시설에서 배출되는 미세먼지를 관리하기 위해서는 미세먼지 배출실태 연구가 필요하다. 미세먼 지는 입자상물질로 직접 배출되는 여과성 먼지(FPM)과 굴뚝 내의 고온으로 인해 가스상 형태로 존재하고 있다가 굴뚝에 서 배출됨과 동시에 대기 중 공기와 희석되면서 냉각 또는 응축되어 입자화되는 응축성 먼지(CPM)로 분류할 수 있다. 본 연구에서는 미세먼지를 다량 배출하는 것으로 알려진 발전시설을 대상으로 여과성 먼지와 응축성 먼지 측정을 수행하였 고, 여과성 먼지 중 이온성분, 중금속성분, 탄소성분을 분석하였다. 그 결과, FPM(PM2.5)은 석탄화력발전시설에서 1.85~2.02 mg/m3, LNG 발전시설에서는 0.02 mg/m3으로 나타났으며, CPM은 석탄화력발전시설에서 9.08~12.20 mg/m3, LNG 발전시설에서는 1.02 mg/m3으로 나타났다.

As people have become more aware of fine particulate matter (PM2.5) recently, there have been growing concerns over the harmful impact of PM2.5 on human health. Since stationary sources are a major source of PM2.5 emission, measures to manage and reduce PM2.5 emission from the stationary sources need to be taken. PM2.5 primary emissions from stationary sources contain a filterable and condensable portion. Filterable PM are particles directly emitted from a stack in a solid or liquid form at stack conditions and captured in the filter of a sampling train. Condensable PM is a material that stays as gas within the stack but is condensed, diluted and/or cooled into solid or liquid particles in the ambient air immediately after discharge from the stack. In this study, the emission characteristics of filterable and condensable PM from power plants are investigated. The average filterable PM2.5 concentration from two coal-fired power plants ranged from 1.85 to 2.02 mg/m3 and that from an LNG power plant was 0.02 mg/m3. The average condensable PM2.5 concentrations from the coal-fired power plants and the LNG plant were 9.08-12.20 mg/m3 and 1.02 mg/m3, respectively.
