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.

琶洲国家出版中心挥发性有机物浓度分布研究

帕州国家出版中心排放了许多挥发性有机化合物。挥发性有机物作为臭氧和二次有机气溶胶的前体，对气候变化、空气质量退化和人类健康产生影响。在这项研究中，我们使用移动实验室上的质子转移反应飞行时间质谱仪（PTR ToF Ms）实时监测设备，测量了2021年9月9日至9月11日帕州国家出版中心的浓度。流动测量发现，用甲苯（22.51±2.14%）、甲醇（19.04±0.96%）和丙酮（16.39±0.61%）对琶洲国家出版中心挥发性有机物的优势种进行了调查。9月9日（M6）、9月10日（M8）和9月11日（M15）的挥发性有机物时空分布以高浓度为主。此外，热图分析表明，印刷业附近有一个高污染地区。根据VOCs的分布特点，可以想象，小规模的工业排放控制可以改善区域空气质量。
