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. KCI Citation Count: 0
