Atmospheric Aerosols: Source Apportionment, Characterizations, and Detection

Dear Colleagues,

The impact of atmospheric aerosols on climate, air quality, and human health has drawn significant attention in recent years. Understanding the sources, chemical compositions, and detection methods of atmospheric aerosols is crucial for accurately assessing their contributions to air pollution and making effective mitigation strategies. This Special Issue aims to bring together the latest research on source apportionment, chemical characterization, and advanced detection techniques related to atmospheric aerosols. This Special Issue invites researchers and experts in the field of atmospheric science to contribute their original research, reviews, and perspectives on the following topics:

• Source Apportionment: Investigations focusing on identifying and quantifying the major sources of atmospheric aerosols. Contributions may include studies utilizing advanced statistical methods, emission inventories, and modeling techniques to determine the spatial and temporal variations of aerosol sources. Additionally, research on the impacts of source-specific aerosols on climate, air quality, and human health is also welcome;
• Chemical Characterization: Research that advances our understanding of the chemical composition of aerosols, including both organic and inorganic species. Contributions may include studies employing state-of-the-art analytical techniques such as mass spectrometry, chromatography, and spectroscopy to characterize the molecular and elemental composition of aerosols. Investigations on aerosol aging, transformation, and the formation of secondary aerosols are of particular interest;
• Advanced Detection Methods: Exploration of innovative approaches and technologies for the real-time detection and monitoring of atmospheric aerosols. Contributions may include studies on the development of advanced sensors, remote sensing techniques, and online monitoring systems for accurate and continuous measurements of aerosol properties. Investigations into the integration of different detection methods to improve spatial coverage and data quality are also encouraged;
• Aerosol–Climate Interactions: Studies investigating the complex interactions between atmospheric aerosols and climate. Contributions may include research on aerosol–cloud interactions, radiative forcing, aerosol impacts on precipitation patterns, and feedback mechanisms. Investigations exploring the regional and global climate effects of different aerosol types and sources are welcome;
• Policy Implications and Mitigation Strategies: Discussions on the policy implications of aerosol research and the development of effective mitigation strategies. Contributions may include studies on the assessment of air pollution regulations, evaluation of emission control measures, and the integration of aerosol-related research into environmental and public health policies.

By addressing these multidisciplinary aspects, this Special Issue aims to provide a comprehensive platform for researchers and policymakers to exchange knowledge, share insights, and foster collaborations to address the challenges associated with atmospheric aerosols.

We look forward to receiving your contributions.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
