PTR-ToF-MS를 이용한 석유화학단지 주변의 VOCs 분포 특성에 관한 연구 A Study on Temporal-Spatial Characteristics of Volatile Organic Compounds Distributed near Petrochemical Industrial Complex using PTR-ToF-MS Abstract Petrochemical industrial complex emit many VOCs. As a precursor of the secondary organic aerosol, VOCs cause
various health issues. In this study, we used a real-time monitoring device to measure the concentration near the petrochemical
industrial complex. The proton transfer reaction-time of flight-mass spectrometer (PTR-ToF-Ms) is used in various mobile research
due to its ability to measure each of many different VOCs. The main wind direction was northwest during the measurement
period. The measurement using the mobile laboratory (ML) was performed with fixed and mobile measurement. In fixed
measurement, the emission process, rather than wind direction, appeared to have a larger effect on the area of the
petrochemical industrial complex. Mobile measurements were found to be high at landfills, dormitories, and intersections. The
concentration of Benzene exceeded the annual guideline with 3.1 ppb and continuously fluctuated over time. While the standard
method can obtain accurate measurements, it does not allow us to monitor measurement of change over time. This necessitates
a new real-time monitoring method that can effectively manage industrial facilities. Key words PTR-ToF-MS, VOCs, Real-time monitoring, Petrochemical industrial complex, Mobile laboratory ▶출처 : 한국대기환경학회지 제 37권 제 5호, 2021.10 |
