Special Issue Information
Dear Colleagues,
Aerosol particles, also referred to as particulate matter, can cause adverse health effects, such as aggravation of asthma, cardiovascular disease, lung disease, and even premature death. Particulate matter less than 2.5 micrometers in size (PM2.5) is the main cause of severe regional air pollution and contributes to acid deposition, causing damage to local ecosystems. Aerosol particles can either be directly emitted into the atmosphere (primary particles) or form from the reaction and condensation of gaseous chemicals already existing in the atmosphere (secondary particles). Primary particles have natural and anthropogenic sources, with the latter contributing most, including incomplete combustion of fossil fuels, transport emissions, agricultural activities, and domestic heating. However, the emissions, transport, and transformation processes remain far from being fully understood for both PM2.5 and its precursors, limiting our ability to develop air pollution control strategies and to protect human health and the environment.
This Special Issue aims to investigate how airborne particles change due to chemical reactions and aerosol dynamical processes that occur during atmospheric transport away from the source of pollution, and the mixing with aerosol particles from other natural and anthropogenic sources. In order to control severe haze pollution and develop effective emission reduction measures, the need arises for additional measurements and modeling studies, tracing the development of particle pollution from sources to local and regional scales, and better characterizing the chemical/physical properties, spatiotemporal variations. and sources of ambient aerosols.
In this Special Issue, original research articles and reviews related to the sources, atmospheric transformation, and dispersion of aerosol particles are welcome. Research areas may include (but are not limited to) the following: aerosol chemistry in regional-scale air pollution models; measurements of particulate matter and its components combined with air mass trajectories; emission characterization; source apportionment; and dispersion modeling of ultrafine particles. Atmospheric studies of particle-bound toxic compounds such as heavy metals and polycyclic aromatic hydrocarbons (PAHs) are of specific interest due to their relevance for human health.
We look forward to receiving your contributions.

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.
