A Study on Distribution of Volatile Organic Compounds Concentration over Paju National Publishing Complex
Journal of Korean Society for Atmospheric Environment(2022)
摘要
Paju National Publishing Complex emitted many Volatile Organic Compounds(VOCs). As a precursor of ozone and secondary organic aerosol, VOCs effected on climate change, air quality degradation, and human health. In this study, we used a real-time monitoring device of proton transfer reaction-time of flight-mass spectrometer(PTR-ToF-Ms) on board a mobile laboratory to measure the concentration on the Paju National Publishing Complex from September 9 to September 11, 2021. Mobile measurement found that dominant species of VOCs in the Paju National Publishing Complex are investigated with toluene(22.51 +/- 2.14%), methanol(19.04 +/- 0.96%), and acetone(16.39 +/- 0.61%). Temporal and spatial distributions of VOCs on Sep. 9(M6), Sep. 10(M8), and Sep. 11(M15) cases showed mostly high concentrations. Moreover, heatmap analysis suggested a high pollution area near the printing industry. Based on the characteristics of VOCs distribution, it is conceivable that small-scale industry emission control could lead to regional air quality improvement
