摘要
2022年5-12月,采用挥发性有机物连续自动监测系统,对包头市城区挥发性有机物进行了实时连续监测,对其污染特征、臭氧生成潜势(OFP)进行了研究,并利用PMF源解析模型对VOCs的来源进行了解析.结果表明,前体物浓度最高值出现在9月,2022年VOCs整体浓度贡献以烷烃为主,烯烃和芳香烃对O3生成影响较大.结合来源分析,应重视机动车尾气排放、燃料燃烧及工业生产等源产生的影响.
Abstract
The VOCs in the area of Baotou were continuously observed in real time by the VOCs on-line continu-ous automatic monitoring system From May to December 2022.The VOC concentration characteristics,ozone pollu-tion process were analyzed.Source apportionment conducted based on PMF were comprehensively analyzed.The re-sults showed that the highest concentration of the precursors occurred in September,and the main contribution of VOCs concentration in 2022 was from alkanes.Combined with source analysis,we should pay attention to the influ-ence of vehicle emission,fuel combustion and industrial production.
