Special Issue Information
Dear colleagues,
Polycyclic aromatic hydrocarbons (PAHs) such as benzo[a]pyrene and nitropolycyclic aromatic hydrocarbons (NPAHs) such as 1-nitropyrene are ubiquitous environmental organic pollutants. Atmospheric PAHs and NPAHs originate primarily from the imperfect combustion of organic matter, with common sources including coal, oil, and biomass combustion. In addition, PAHs and their branched derivatives are contained in petroleum and are therefore problematic components of oil spills in marine ecosystems. Many PAHs and NPAHs are carcinogenic and/or mutagenic. Recently, the World Health Organization categorized PM2.5 as a Group 1 contaminant (carcinogenic to humans) because of the PAHs and NPAHs contained within. Moreover, metabolites of PAHs and NPAHs, such as the hydroxylated and quinoid derivatives, act on the endocrine system while also initiating reactive oxygen species production. Therefore, it is important to further investigate how these components of PM2.5 may impact organisms at the cellular and biochemical levels. Many world regions, such as East Asia, are highly polluted with PAHs and NPAHs, given the recent rise in economic and industrial activity. However, the extent of pollution differs greatly depending on the energy sources used such as oil, coal, biomass, or natural gas. Therefore, understanding the linkage between source and the types of PAH congeners produced is an important first step in addressing these pollution problems. Papers addressing these topics are invited for this Special Issue.

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. International Journal of Environmental Research and Public Health 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 2500 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.
