To gain insight into the impact of changes due to epidemic control policies, we undertook continuous online monitoring of volatile organic compounds (VOCs) at an urban site in Zhengzhou over a 2-month period. This study examines the characteristics of VOCs, their sources, and their temporal evolution. It also assesses the impact of the policy change on VOC pollution during the monitoring period, thus providing a basis for further research on VOC pollution and source control.

This paper introduces a novel approach for improving the computational efficiency and scalability of source-oriented chemical mechanisms by simplifying the representation of reactions involving source-tagged species and implementing a source-oriented Euler backward iterative (EBI) solver. These advancements reduce simulation times by up to 74 % while maintaining accuracy, offering significant practical benefits for long-term source apportionment studies.

Analyzing 12-year Zhengzhou data revealed post-2019 crustal material rebound caused by soil dust resuspension, elevating particle pH. Similar coarse particle increases are observed across cities of the North China Plain. Long-term particle acidity evolution in this region requires an integrated assessment of interactions among acidic precursors, ammonia, and crustal components.

This study investigates O3 pollution in Zhengzhou. The results show that traffic and industrial emissions are the main sources of O3 and its precursors. The study highlights the significant impact of local emissions and the role of atmospheric free radicals in ozone formation. Reducing emissions of aromatics and alkenes can effectively reduce ozone pollution. These findings stress the importance of controlling traffic and industrial sources to mitigate O3 pollution.

This study highlights the importance of the redox reaction of NO2 with SO2 based on actual atmospheric observations. The particle pH in future China is expected to rise steadily. Consequently, this reaction could become a significant source of HONO in China. Therefore, it is crucial to coordinate the control of SO2, NOx, and NH3 emissions to avoid a rapid increase in the particle pH.

In this study, the hourly data of 57 VOC species were collected during 2018–2020 at an urban site in Zhengzhou, China. The research of concentrations, source apportionment, and atmospheric environmental implications clearly elucidated the differences in major reactants observed in different seasons and years. Therefore, the control strategy should focus on key species and sources among interannual and seasonal variations. The results can provide references to develop control strategies.

This study measured 106 VOC species using a GC-MS/FID. Meanwhile, the WRF-CMAQ model was used to investigate the nonlinearity of the O3 response to precursor reductions. This study highlights the effectiveness of stringent emission controls in relation to solvent utilization and coal combustion. However, unreasonable emission reduction may aggravate ozone pollution during control periods. It is suggested that emission-reduction ratios of the precursors (VOC : NOx) should be more than 2.

Short summary
The increasing concentration of O3 precursors and unfavorable meteorological conditions are key factors in the formation of O3 pollution in Zhengzhou. Vehicular exhausts (28 %), solvent usage (27 %), and industrial production (22 %) are identified as the main sources of NMVOCs. Moreover, O3 formation in Zhengzhou is found to be in an anthropogenic volatile organic compound (AVOC)-limited regime. Thus, to reduce O3 formation, a minimum AVOCs / NOx reduction ratio ≥ 3 : 1 is recommended.
The increasing concentration of O3 precursors and unfavorable meteorological conditions are key...
