Air pollution remains a pressing global issue, prompting nations worldwide to implement various mitigation strategies, often targeting specific pollutants such as particulate matter. While these strategies are crafted with the best intentions, they sometimes yield unintended effects, including changes in atmospheric chemical composition that lead to phenomena such as increases in ozone or unforeseen climate impacts.

This session aims to shed light on the unintended consequences of air pollution mitigation strategies, focusing on the changes in chemical composition induced by these strategies. We invite contributions that delve into the observational data, modeling approaches, and projections of future changes to better understand the full spectrum of effects of pollution control measures. By fostering a discussion grounded in rigorous scientific analysis, we hope to pave the way for more holistic and effective strategies in the future, balancing the urgent need to reduce pollution with a deep understanding of potential unintended effects. We welcome submissions that employ a range of research methods, including - but not limited to - observational studies and modeling to forecast future changes, encouraging a multidisciplinary approach to a complex issue.
