Fine Particulate Matter (PM2.5) in a Changing Climate

Dear Colleagues,

Ambient particulate matter PM2.5 is defined as particles whose aerodynamic diameter is 2.5µm or less. The sources of PM2.5 particulate pollution include industry, transport, natural, soil dust, and sea spray, to list a few. Particle size, shape, density, chemical composition, and biological and physical properties have been identified as key PM2.5 characteristics in climate, environment, and health studies. A few studies have reported on the effects of PM2.5 particulate pollution on climate change, global warming, reduction in visibility, changes in earth radiation balance, and cloud formation.

There is epidemiological evidence that human exposure to PM2.5 particulate pollution increases mortality and morbidity from cardiovascular and respiratory disease. Recent studies have demonstrated that long-term exposure to particulate air pollution, and especially PM2.5, is associated with dementia and type 2 diabetes mellitus, and a probable risk factor for the weight status of children and adolescents. Short-term and long-term PM2.5 particulate exposure has been identified as an important risk factor for COVID-19.

However, there is limited research in developing countries on PM2.5 particulate pollution; thus, we would like to receive papers on the subject from developing countries. Papers on detection methods, sample collection, and analysis related to PM2.5 are welcome. We would like to receive papers on the health effects of PM2.5 particulate pollution, including large-scale studies on PM2.5 exposure.

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. Climate 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 1800 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.
