Special Issue Information

Dear Colleagues,

Air pollution control is an ongoing subject of concern regarding human health, especially regional O3 pollution, which arises as a secondary consequence of VOCs and NOx as precursors. In addition, O3, NOx, VOC, and CO2 emissions have also had a significant impact on climate change. The industry sector has emerged as the predominant contributor to air pollutants and carbon emissions due to its high quantity and intensity of emissions. However, the control of air pollution in industrial parks still faces challenges due to their limited scale, intricate emissions, and diverse meteorological factors.

The accurate source tracing of O3 and its precursors is fundamental for effective air quality management and control strategies, while efficient disposal techniques are crucial for reducing emission quantities. Therefore, the focus of this Special Issue is on presenting advanced techniques, including O3 formation investigation, source tracing, and pollutant disposal methods for VOCs and NOx, within the context of collaborative carbon emission reduction efforts. The focus of this Special Issue is on the mechanisms of O3 formation, the source tracing of O3 and its precursors, the disposal of VOCs and NOx pollution, and carbon capture, as well as advanced studies on emission inventory, source profiles, and carbon emission accounting in industrial parks or sectors. The aim of this Special Issue is to present the most recent research on the advancements, challenges, and prospects in the cooperative control of air pollution and carbon emissions.

Ozone pollution in chemical industrial parks is severe and complicated and is significantly influenced by pollutant emissions and meteorological parameters. In this study, we innovatively investigated the formation rules of ozone by using observation-based analyses and a gradient-boosting decision tree (GBDT) model, focusing on a typical chemical industrial park located in the Yangtze River Delta of China. The results revealed that ozone concentration was positively correlated with temperature while negatively correlated with NO2 concentration and relative humidity (RH). Ozone pollution was predominantly observed from April to October (M4–10). The optimized GBDT model was subsequently utilized to establish a specific and quantifiable relationship between each single dominant impact factor (RH, NO2, temperature, and PM2.5) and ozone within a complex and uncertain multi-factor context during M4–10. Detailed discussions were conducted on the reaction rate of ozone-related to different levels of RH and temperature. The accumulation of ozone was favored by high temperature and low RH, with the maximum ozone concentration observed at the RH of 50% and the temperature of 35 °C. The NO2-O3 change curve exhibited distinct phases, including a period of stability, gradual increase, rapid increase, and equilibrium. During the second and third periods, the ratio of ozone production to NO2 consumption was 0.10 and 2.73, respectively. Furthermore, there was a non-monotonic relationship between variations in ozone concentration and PM2.5 concentration. Hence, it is imperative to implement fine control strategies in the park, such as adopting seasonal production strategies, implementing targeted measures for controlling NOx and active VOCs, and employing special control methods during periods of high temperature. This study provides aid in achieving effective management of localized ozone pollution and ensuring compliance with air quality standards. Full article
