Special Issue Information
Dear Colleagues,
Secondary organic aerosols (SOAs) contribute to a significant fraction of atmospheric particles, profoundly affecting human health, air quality, and climate change. A detailed fundamental knowledge of SOA composition and formation is therefore required. Previous studies have shown that high levels of SOAs formed under atmospheric conditions are attributed to complex chemical and physical processes, and a quantitative and comprehensive understanding of SOA formation mechanisms is still absent. Also, many studies declare the correlations of SOAs with respiratory diseases, highlighting the necessity of SOA composition analysis and risk evaluation. Moreover, SOAs directly affect the Earth’s radiation budget by adsorbing and scattering solar radiation; therefore, the significant role of organic aerosols in the climate system is evident. However, SOA formation and transformation mechanisms remain elusive, resulting in big challenges in understanding their environment and health impacts. This Special Issue solicits original research on the sources, formation, transformation, and impacts of SOAs in the atmosphere. Experimental, theoretical, and field studies concerning SOAs in the atmosphere are encouraged.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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 100 words) can be sent to the Editorial Office for announcement on this website.
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-blind 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.
