Special Issue Information

Dear Colleagues,

The Special Issue, entitled "Coordinated Control of PM2.5 and O3 and Its Impacts in China", explores the challenges and strategies related to managing air pollution, particularly focusing on reducing particulate matter (PM2.5) and ground-level ozone (O3) in China. This Special Issue emphasizes the importance of implementing integrated control measures due to the complex interactions between these pollutants and their combined effects on public health and the environment.

Key topics covered include the following:

  1. Pollution Sources and Emission Characteristics:
  • The identification of major sources of PM2.5 and O3, such as industrial emissions, vehicle exhaust, construction activities, and agricultural practices.
  • The analysis of emission characteristics, considering seasonal and regional variations to understand the intensity and distribution of pollutant sources.
  1. Chemical Mechanisms and Interactions:
  • The study of the chemical processes involved in the formation of PM2.5 and O3, focusing on the role of precursors like NOx and VOCs.
  • The examination of the interactions between PM2.5 and O3, including how changes in the concentration of one pollutant can affect the other.
  1. Health Impacts:
  • The assessment of the health risks associated with exposure to PM2.5 and O3, particularly respiratory and cardiovascular diseases.
  • Focus on the effects on vulnerable populations, including the elderly, children, and individuals with pre-existing health conditions.
  1. Environmental and Climate Impacts:
  • The exploration of the effects of PM2.5 and O3 on ecosystems, including damage to vegetation, soil, and water bodies, and the formation of acid rain.
  • The analysis of the relationship between air pollution and climate change, considering the impact on greenhouse gas effects and regional climate patterns.
  1. Monitoring and Assessment:
  • The development and application of advanced monitoring technologies and methods for the real-time and long-term analysis of PM2.5 and O3 levels.
  • The establishment of scientific assessment frameworks to evaluate the effectiveness of control measures.

The purpose of this study was to analyze the air quality in Hangzhou and its surrounding areas during the 2023 Asian Games and assess the impact of safeguard measures on air quality. By comparing air quality monitoring data from Hangzhou and nearby cities between 23 September 2023, and 8 October 2023, with the same period in 2022, the analysis focused on the changes in air quality and the impact of PM2.5 and O3 on human health. The results show that during the 2023 Asian Games in Hangzhou, compared to the same period in 2022, the concentrations of pollutants showed the following changes: PM10 and NO2 concentrations decreased by 16.1% and 34.1%, respectively. PM2.5, CO, and O3 concentrations increased by 0.9%, 9.5%, and 14.4%, respectively. Spatially, compared with the same period in 2022, the PM2.5 concentration in Quzhou City decreased the most, reaching 23%, while the PM2.5 concentration in Huzhou City increased the most, reaching 27.1%. The largest decrease in PM10 concentration is in Wenzhou City, which is up to 28.2%, while the largest increase is in Zhoushan City, which is 9.2%. The concentration of NO2 generally decreases in all regions, with the biggest decrease in Zhoushan City, which reaches 36.2%. The concentration of CO only decreases in Shaoxing, and the highest increase is in Huzhou City. In terms of O3, the largest proportion increase is 23% in Ningbo. During the 2023 Asian Games in Hangzhou, the number of deaths from all-cause and cardiovascular diseases caused by short-term exposure to PM2.5 was 1780 and 795, respectively, which was 8.2% lower than the same period in 2022. During the Asian Games, the number of deaths from all-cause and cardiovascular diseases due to short-term exposure to O3 was 7332 and 3177, respectively, an increase of 2.8% compared with the same period in 2022.
