Air pollution poses one of the most significant challenges to humanity today, with profound effects on both the climate system and public health. The World Health Organization (WHO) estimates that air pollution impacts 99% of the global population, leading to 4.2 million premature deaths annually. Yet, our ability to predict and mitigate these detrimental effects is limited by the challenges of discerning the primary sources of air pollution as well as constraining the intricate mechanisms governing the formation and secondary pollutants. In order to formulate more effective control policies, it is imperative to develop a multi-faceted and in-depth understanding towards the origins of air pollution and the physicochemical processes responsible for generating key secondary pollutants.
In recent years, as a result of significant advancements in isotopic techniques and theories, isotopic analysis has been successfully applied to the study of air pollution. These developments have led to groundbreaking insights into quantifying sources and specific processes related to air pollution. To offer a comprehensive overview of the progress in understanding the atmospheric environment via isotopic analysis, we are calling for manuscripts covering (but are not limited to) the following subtopics:
1. Cutting-edge techniques for measuring stable isotopes (e.g., 15N, 18O, 17O, 13C, 34S), radioactive isotopes (e.g., 14C, 35S, 129I), and metal isotopes in atmospheric compositions.
2. Advances in theories pertaining to isotopic fractionation effects relevant to the atmospheric environment.
3. Source apportionment of atmospheric pollutants via isotopes using numerical models.
4. Isotopically tracing the physicochemical processes involved in atmospheric pollutants.
Keywords:
air quality, isotope, source apportionment, oxidation pathways, atmospheric processes, aerosols, measurement techniques
Important Note:
All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
