“…Our coupled modeling system makes use of a coarse regional model that provides time-varying background concentrations to drive street-level air dispersion models such as ADMS-Urban, which specializes in capturing rapid chemical reactions. The initial results of the presented Guangzhou case are promising, providing more information on NO x -O 3 sensitivity that is consistent with findings from previous modeling studies (Cheng et al, 2021;Ma et al, 2021;Wu et al, 2021;Zhang, Fung, Lau, Hossain, et al, 2021). This finding indicates that synergistic controls of NO x and VOCs are promising means for the simultaneous mitigation of PM 2.5 and O 3 , consistent with the findings of Wu et al (2021).…”

Ultrahigh‐resolution air quality models that resolve sharp gradients of pollutant concentrations benefit the assessment of human health impacts. Mitigating fine particulate matter (PM2.5) concentrations over the past decade has triggered ozone (O3) deterioration in China. Effective control of both pollutants remains poorly understood from an ultrahigh‐resolution perspective. We propose a regional‐to‐local model suitable for quantitatively mitigating pollution pathways at various resolutions. Sensitivity scenarios for controlling nitrogen oxide (NOx) and volatile organic compound (VOC) emissions are explored, focusing on traffic and industrial sectors. The results show that concurrent controls on both sectors lead to reductions of 17%, 5%, and 47% in NOx, PM2.5, and VOC emissions, respectively. The reduced traffic scenario leads to reduced NO2 and PM2.5 but increased O3 concentrations in urban areas. Guangzhou is located in a VOC‐limited O3 formation regime, and traffic is a key factor in controlling NOx and O3. The reduced industrial VOC scenario leads to reduced O3 concentrations throughout the mitigation domain. The maximum decrease in median hourly NO2 is >11 μg/m³, and the maximum increase in the median daily maximum 8‐hr rolling O3 is >10 μg/m³ for the reduced traffic scenario. When controls on both sectors are applied, the O3 increase reduces to <7 μg/m³. The daily averaged PM2.5 decreases by <2 μg/m³ for the reduced traffic scenario and varies little for the reduced industrial VOC scenario. An O3 episode analysis of the dual‐control scenario leads to O3 decreases of up to 15 μg/m³ (8‐hr metric) and 25 μg/m³ (1‐hr metric) in rural areas.

“…For studies exclusively measuring posttreatment EF s, we calibrated these EF s based on known removal efficiencies (Table S3). These data sets include Technical Guidelines for Compiling Emission Inventory of Atmospheric VOCs Sources for China, the United States Environmental Protection Agency’s (U.S. EPA) Compilation of Air Emissions Factors (AP-42), and SPECIATE 5.2. − The most up-to-date measurements based on China were preferred to enhance the accuracy of the emission estimates. Table S3 provides the list of EF s for individual products.…”

“…In the solvent use industry and chemical industry, however, there are usually fully enclosed and incompletely enclosed production units. VOC samples were collected from stacks of these industries with fully enclosed production units [32], and samples were collected from both major stacks and production areas of these industries where production units were not completely enclosed [33]. The most commonly used sampling materials were solid-phase sorbent tube sampling and container sampling (Table 2).…”

The source profile of volatile organic compounds (VOCs) is essential for establishing reactivity- and toxicity-based emission inventories and developing effective air pollution control strategies. In this paper, the establishment of VOC source profiles and the VOC emission characteristics are reviewed in the petrochemical, solvent use, and chemical industries, and the most up-to-date profiles of the three industries in China are compiled via necessary adjustment and reconstruction of the test data from the literature. Alkanes dominated and OVOCs were often neglected in the overall petrochemical industry and refined processes. They accounted for 60.6% and 3.2% in the merged profiles. Aromatics and OVOCs dominated in the industrial solvent use industry. OVOCs were the most prevalent in the printing and dyeing industries, furniture manufacturing industries, and automobile coating process, whereas aromatics were major contributors of the total VOCs in metal surface coating, shipping coating, and other surface coating industries in the merged profiles. A wide range of products and limited profile studies were obtained in chemical industry, and the compositions of VOCs varied significantly in the production of 30 products in the merged profile. The future research directions of VOC source profiles are discussed, mainly focusing on the sampling, establishment, and evaluation of VOC profiles.
