Abstract

Analysis of ambient air samples for 117 volatile organic compounds (VOCs) was performed from April to September 2020 in Tangshan City using preconcentration-GC/MS and high-performance liquid chromatography methods. During sampling, daily average concentration of total VOCs (TVOC) varied from 42 µg/m³ to 213 µg/m³. Contributions of alkanes, OVOCs, aromatics and halogenated hydrocarbons to TVOC were 32%, 28.7%, 18.4%, and 11.0%, respectively, and formaldehyde, propane, acetone, aldehyde, toluene, ethylene, m/p-xylene, n-butane and chloromethane were the dominate species of VOCs in Tangshan City. Results of source apportionment showed that vehicle emissions, combustion, gasoline evaporation and solvent usage were 4 important sources of VOCs in Tangshan. Aromatics contributed 48.7% to total ozone formation potential (OFP), followed by OVOCs, alkenes and alkanes, contributing 26.6%, 14.9% and 9.4% to total OFP, respectively. Arranged in descending order, the 10 species contributing most to total OFP were m/p-xylene, formaldehyde, toluene, acetaldehyde, ethylene, o-xylene, ethylbenzene, propylene, 1-butene and isopentane, and their contributions to total OFP were 19.1%, 17.3%, 11.5%, 7.7%, 7.6%, 7.6%, 3.5%, 2.0%, 2.0% and 1.5%, respectively. The sensitivity of ozone (O₃) production was studied with an empirical kinetic modeling approach (EKMA) model. It was found that ozone formation in Tangshan City was under VOC-limited conditions, indicating the importance of emission reduction of VOCs to ozone pollution control.
