A Study on Distribution of Volatile Organic Compounds Concentration over Paju National Publishing Complex

Abstract 

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.
