Abstract: The anthropogenic VOCs emission sources of Beijing-Tianjin-Hebei (BTH) regions on the base year of 2018 were taken as the research object, the emission inventory containing various industries and species was established, the ozone formation potential (OFP) and secondary organic aerosol formation potential (SOAP) of different VOCs sources were obtained. The VOCs emission source priority control classification technology method was constructed, and the classification index of each emission source was calculated. Results showed that the total emission amount of VOCs from anthropogenic sources in the BTH regions in 2018 was 2.140 million tons, with mobile sources accounting for the largest proportion, followed by industrial process sources and solvent utilization sources. The total OFP and SOAP contributed by these VOCs sources was 6.982 million tons and 36,000 tons in respective, among which small passenger cars, industrial protective coating, heavy trucks and coking were the predominant sources. The VOCs priority control classification index is calculated combining the emission amounts, OFP and SOAP of various VOCs emission sources. The indexes of industrial protective coatings, small passenger cars, heavy trucks, coking, iron/steel, heating combustion, and biomass combustion were obviously larger. In order to achieve the scientific and collaborative prevention and control of PM_2.5 and O₃, it is suggested to strengthen the control of the above emission sources. The results can provide scientific and technological support for the next stage of combined pollution prevention and control in the BTH regions.
