Atmospheric Pollution in Highly Polluted Areas

Dear Colleagues,

Air pollution remains the greatest environmental health threat worldwide, with only seven countries meeting the WHO annual PM_2.5 guideline (annual average of 5 µg/m3 or less) in 2023. Moreover, in some countries and regions, the PM_2.5 concentrations exceed the standard by more than five times, such as in Central Asia, South Asia, North Africa, Southern Europe, Latin America, China’s NCP region, and so on. Research regarding air pollution in these regions is often lagging and insufficient due to the economic development constraints. However, under conditions of unique emission characteristics, meteorological conditions, and geographical locations, the formation mechanisms of atmospheric pollution may vary, thus necessitating in-depth research. Therefore, we aim to promote the publication of papers focusing on air pollutants in highly polluted areas in this Special Issue. In particular, whether original research papers or review articles, the Special Issue invites studies including, but not limited to, the following topics:

1. Investigating the characteristics of air pollutants in pollution progress;
2. Exploring the sources and formation mechanisms of air pollutants in highly polluted areas;
3. Assessing the impacts of air pollutants on human health, ecosystems, and climate systems;
4. Discussing strategies and interventions for mitigating air pollution and improving air quality.
