PTR-ToF-MS를 이용한 국내 산업업종별 휘발성유기화합물 배출특성 연구

Source characterization of volatile organic compounds of industrial complex measured by proton-transfer-reaction

time-of-flight mass spectrometers in Korea

Abstract 

We used the measurement data derived from a proton transfer reaction time-offlight mass spectrometry (PTR-ToF-MS) to

ascertain the source profile of volatile organic compounds (VOCs) from 4 major industrial classifications which showed

the highest emissions from a total of 26 industrial classifications of A industrial complex. Methanol (MOH) was indicated as the

highest VOC in the industrial classification of fabricated metal manufacture, and it was followed by dichloromethane

(DM), ethanol (EN) and acetaldehyde (AAE). In the industrial classification of printing and recording media, the

emission of ethylacetate (EA) and toluene (TOL) were the highest, and were followed by acetone (ACT), ethanol (EN)

and acetic acid (AA). TOL, MOH, 2-butanol (MEK) and AAE were measured at high concentrations in the classification of rubber and plastic manufacture. In the classification of sewage, wastewater and manure treatment, TOL was the

highest, and it was followed by MOH, H2S, and ethylbenzene (EBZ). In future studies, the source profiles for various

industrial classifications which can provide scientific evidence must be completed, and then specified mitigation plans of

VOCs for each industrial classification should be established.
