宿迁市秋季初期的挥发性有机物污染特征分析

Analysis on Characteristics of Volatile Organic Compounds Pollution in Suqian City in Early Autumn

近年来,臭氧已经逐渐成为制约宿迁市环境空气质量改善的主要因素。VOCs作为臭氧的前体物,已成为大气环境管理的重点,受到了前所未有的关注。为进一步了解宿迁市秋季VOCs来源及污染成因,对宿迁市秋季初的挥发性有机物污染开展监测,监测区域为中心城区,采用受体模型PMF对观测期间115种VOCs物种开展来源解析,结果表明,有机溶剂使用源是对VOCs贡献最大的排放源,占比为37.88%,其次是汽车尾气排放、生物质燃烧。VOCs组分监测仪器是ZF-PKU-VOC-1007大气挥发性有机物快速在线监测系统。其间,充分发挥定性定量准确、灵敏度高、监测因子覆盖范围广等优势,能够更好地为宿迁市大气污染防治工作提供支撑。

In recent years,ozone has gradually become the main reason that restricts the improvement of ambient air quality in Suqian City.As the precursor of ozone,VOCs have become the focus of atmospheric environmental management and received unprecedented attention.In order to further understand the source of VOCs and the causes of pollution in Suqian in autumn,The volatile organic pollutants in Suqian City were monitored in the early autumn in the central urban area,The receptor model PMF was used to analyze the source of 116 VOCs species during the observation period.The results showed that the source of organic solvent use was the largest contributor to VOCs,accounting for 37.88%,followed by vehicle exhaust emissions and biomass combustion.The VOCs component monitoring instrument is a ZF-PKU-VOC-1007 rapid online monitoring system for volatile organic compounds in the atmosphere.Give full play to the advantages of accurate qualitative and quantitative analysis,high sensitivity,and wide coverage of monitoring factors,so as to better support the air pollution prevention and control work in Suqian City.
