Abstract

Emission from biomass combustion such as meat charbroiling is an important source of organic aerosol. Since source profiles are necessary input profiles for source apportionment of aerosol by a chemical mass balance model, meat cooking organic source profiles are developed by measuring organic marker compounds, including palmitic acid, stearic acid, oleic acid and cholesterol as well as PAH compounds. Emissions from meat and pork charbroiling are collected on quartz filters with a PM10-high volume sampler, extracted with organic solvents, derivatized with diazomethane/TMS and analyzed by GC/MS isotope dilution method. Organic and elemental carbon are also analyzed by an OCEC analyzer. Wt.% of cholesterol to the organic carbon(OC) content from beef and pork charbroiling is only 0.056 and 0.062, but wt. % of all saturated fatty acids to the OC content from beef and pork charbroiling is 2.727 and 2.022, and the wt% of all unsaturated fatty acids to the OC content is 0.278 and 0.438, respectively. Content of total PAH compounds to the OC content from beef charbroiling is higher than that from pork charbroiling, and those are 0.116 wt% and 0.044 wt%. Among PAH compounds benzo(a)pyrene as a single compound is account for 0.0071 wt% and 0.0023 wt% of OC content from beef and pork charbroiling. Ratios of marker compound to cholesterol are calculated, and those values are in good agreement with the values already reported at the food cooking emission, indicating that they can be used as organic source profiles for the apportionment of organic aerosol.

고기구이 스모크와 같은 바이오매스 소각에서 발생하는 스모크는 도시의 미세먼지중 유기성 탄소물질을 구성하는 주요 오염원이다. 미세먼지의 오염원 기여도를 산출하기 위한 화학수지모델(Chemical Mass Balance:CMB)에서는 배출원 오염물분포자료(Source Profile)가 필수이다. 바이오매스를 비롯한 고기구이 스모크의 오염물분포자료를 작성하기 위하여 유기성 지표물질들을 분석하였다. 고기구이에서 발생한 스모크를 PM10 채취기로 채취하여 용매추출, 유도체화반응, 중수소가 함유된 표준물질을 투입하여 Gas chromatography/Mass Spectrometry(GC/MS)로 팔미트산, 스테아르산, 올레인산과 같은 지방산과 콜레스테롤, 다환방향족탄화수소를 측정하였으며, 동시에 PM10 필터시료의 유기성(OC) 및 원소성 탄소(EC)를 OCEC 분석기에 의하여 측정하였다. 쇠고기구이 스모크로부터 채취한 PM10시료의 OC에서 콜레스테롤, 총포화지방산, 불포화지방산의 함량은 0.056 wt%, 2.727 wt%, 0.278 wt%이며, 돼지고기 구이 스모크로부터 채취한 PM10시료의 OC에서는 0.062 wt%, 2.022 wt%, 0.438 wt%를 차지하고 있었다. 쇠고기와 돼지고기 구이 스모크 OC에서 총 PAH화합물의 함량은 0.116 wt%와 0.044 wt% 이었는데, 그중에 단일 화합물로서 benzo(a)pyrene은 0.0071 wt%와 0.0023 wt%이었다. 콜레스테롤을 기준으로 각 지표물질의 무게 비율은 외국에서 발표된 고기구이 배출원 오염물분포자료와 거의 일치하여 유기성 에어로솔의 오염원 기여도를 산출하는 배출원 오염물분포자료로서 사용할 수 있음이 확인되었다.
