Ground-level ozone (O3) pollution has received widespread attention because its rising trend and adverse ecological impacts. However, the extremely strong photochemical reactions of precursor volatile organic compounds (VOCs) increase difficulty reducing VOCs emissions to alleviate O3. Here, we carried out a one-year comprehensive observation in two representative cities, Tianjin (TJ, Northern China) Guangzhou (GZ, Southern China). By revealing concentration characteristics three different types VOCs, i.e., initial without reaction (In-VOCs), consumed (C-VOCs), measured after (M-VOCs), elucidated important role C-VOCs formation Although overall trends were similar both average level GZ was 8.2 ppbv higher than that TJ, loss greater by 2.2 ppbv. In addition, various drivers affecting O3 generation from specifically explored, it found most alkenes TJ key substances for rapid compared aromatics GZ. Meanwhile, favorable meteorological conditions such as high temperature (T > 31 °C T 33 GZ), low relative humidity (56% 45% stable atmospheric environment (proper pressure gentle wind speed) also contribute More importantly, combined chemical kinetics receptor model quantify three-type source contributions assess potential impact sources on production, thus proposing environmental abatement technologies corresponding VOCs. The differences comparison results highlight need reduce sources, which provides insights future clean air policies development.

Photochemical losses of ambient volatile organic compounds (VOCs) substantially affect source apportionment analysis. Hourly speciated VOC data measured from April to August 2020 in Tianjin, China were used analyze the photochemical species and assess impacts on by comparing positive matrix factorization (PMF) results based observed initial concentration (OC-PMF IC-PMF). The concentrations estimated using a age-based parameterization method. suggest that average loss total VOCs (TVOCs) during ozone pollution period was 2.4 times higher than non-ozone period. alkenes more significant other species. Temperature has an important effect losses, different have sensitivities temperature; high mainly occurred at temperatures between 25 °C 35 °C. reduced highly reactive OC-PMF factor profile. Compared with IC-PMF results, contributions biogenic emissions polymer production-related industrial sources underestimated 73 % 50 %, respectively, likely due oxidation isoprene propene, respectively. contribution diesel gasoline evaporation 39 which m,p-xylene.
