Abstract:
Volatile organic compounds (VOCs) are important precursors of fine particulate matter and ozone, and have a significant impact on the formation of complex pollution in China. The Beijing-Tianjin-Hebei Region is suffering from serious air pollution problem, with complex VOCs sources and large amount of emissions. Thus, it is urgent to form a VOCs control strategy based on atmospheric reactivity. The anthropogenic VOCs emission sources of the Beijing-Tianjin-Hebei Region were taken as the research object, an 2018 emission inventory covering various industries and species was established. The VOCs spectra were obtained from field observations and collection of previous studies. The ozone formation potential (OFP) and secondary organic aerosol formation potential (SOAP) of different sources were thus acquired. The VOCs emission source priority control classification technology method was constructed. The classification index of each emission source was calculated and emission sources for priority control were identified. The results showed that: (1) The total amount of anthropogenic VOCs emissions in the Beijing-Tianjin-Hebei Region in 2018 was 2.140 million tons, and main components were arranged in the order of aromatic hydrocarbons, alkanes and oxygenated organic compounds. (2) Small buses, industrial protective coatings, heavy goods vehicles, coking industry were the predominant sources of OFP and SOAP. (3) The classification index was calculated based on the emissions of various sources, industrial protective coatings, small buses, heavy goods vehicles, coking, steel, heating combustion, biomass combustion ranked in the top. It was indicated that there were certain limitations in formulating control strategies based on the single factor of industry VOCs emissions, OFP and SOAP. In order to achieve the scientific and collaborative prevention and control of PM2.5 and O3, it is suggested to strengthen the control of the emission sources obtained based on multi factors. © 2023 Editorial Board, Research of Environmental Sciences.
