摘　　要：随着深圳超大城市工业化聚集水平和城市化发展水平提高,且城市土地供应面积受限,人口增加使得工业园区周边建设的住宅区密集度提高,工业园区内排放的废气对周边居民住宅区空气质量影响愈加被重视,此次搭载GC-MS监测系统走航监测车对两个工业园区点位开展空气质量监测,选取2024年8月28日~9月12日大气中VOCs监测数据进行分析。结果表明:受两个工业园区制造企业排放废气影响,走航观测结果 VOCs种类主要划分为含氧化合物、烷烃、芳香烃、烯烃、卤代烃、有机硫六项,两个工业园区的TVOC日平均浓度为179.21μg/m^(3)与204.78μg/m^(3)。两个工业园区VOCs主要成分是乙酸乙酯与二氯甲烷。臭氧生成潜势贡献前三的组分为乙酸乙酯、甲苯、间/对二甲苯。监测分析结果为监管单位加强对周边园区企业涉及油气挥发、有机废气车间和原辅料仓库、露天喷漆、废气处理不规范等问题的排查整治提供决策依据。With the improvement of the industrial agglomeration level and urbanization development level in the super-large city of Shenzhen,and the limited supply area of urban land,the increasing population has led to a higher density of residential areas built around industrial parks.The impact of the exhaust gases emitted within industrial parks on the air quality of surrounding residential areas has more and more importance to.This time,the mobile monitoring vehicle equipped with the GC-MS monitoring system carried out air quality monitoring at two locations in the industrial parks.The monitoring data of VOCs in the atmosphere from Aμgust 28t h to September 12 th,2024 were selected for analysis.The results show that:Affected by the exhaust gases emitted by manufacturing enterprises in the two industrial parks,the types of VOCs observed during the mobile monitoring can be mainly classified into six categories:oxygenated compounds,alkanes,aromatic hydrocarbons,olefins,halogenated hydrocarbons,and organic sulfur.The average daily concentrations of TVOC in the two industrial parks are 179.21μg/m^(3) and 204.78μg/m^(3) respectively.The main components of VOCs in the two industrial parks are ethyl acetate and dichloromethane.The top three components contributing to the ozone formation potential are ethyl acetate,toluene,and m/p-xylene.The results of the monitoring and analysis provide a decision-making basis for regulatory authorities to strengthen the investigation and rectification of problems such as oil and gas volatilization,organic waste gas workshops,raw and auxiliary material warehouses,open-air painting,and non-standard waste gas treatment involving enterprises in the surrounding industrial parks.
