Special Issue Information
Dear Colleagues,
Millions of people in China have been estimated to die from heart, lung, and stroke problems due to exposure to air pollution, with an estimated death toll of 30 million since 2000. The majority of this mortality is due to exposure to fine aerosols (i.e., particulate matter of 2.5 microns or less in diameter; PM2.5), which can reach deep into the lungs and even into the bloodstream, posing a great risk to human health. According to the latest census data in 2020, about 64% of the total population in China is currently living in cities, and that number is expected to increase to 70% by 2030. However, rapid urbanization can cause air pollution due to, e.g., excessive consumption of energy, the concentration of population, an increase of urban land use, etc. To address issues with urban air quality in China, innovative sampling methods, novel analytical techniques, and methodologies are needed to obtain a better understanding of the sources of PM2.5, as well as the factors influencing the PM2.5 concentration levels on a local to regional scale.
This Special Issue aims to provide recent advances in the understanding of the sources (e.g., primary vs. secondary) of PM2.5 and the factors (e.g., meteorological parameters, distance from the emission sources, urban landscape, dispersion, transport, etc.) affecting the PM2.5 concentration levels that are critical to mitigating their negative impact on urban air quality in China. Topics of interest for the Special Issue include but are not limited to:
- Urban air quality;
- Aerosol sources;
- Black carbon;
- Secondary organic aerosol;
- Atmospheric Chemistry;
- Air pollution remote sensing.

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. Atmosphere 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 2400 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.
