Halogenated Polycyclic Aromatic Compounds (HPACs): Bridging the Gaps in Occurrence, Exposure, and Toxicological Risk

Dear Colleagues,

Halogenated Polycyclic Aromatic Compounds (HPACs), which include HPAHs and other halogenated derivatives, represent a critical, yet under-investigated, class of environmental contaminants. Unlike their well-studied parent compounds, HPACs often exhibit enhanced persistence, bioaccumulation potential, and toxicity, posing an emerging global risk.

This Special Issue invites contributions that move beyond traditional monitoring to unravel the complete environmental and toxicological profile of HPACs. We seek manuscripts that apply non-target screening to identify novel congeners, characterize their ubiquitous occurrence and source apportionment in complex environmental matrices, and clarify their environmental fate and transport pathways. A particular focus is on understanding human and ecological exposure and utilizing bioanalytical tools to assess the combined biological impacts of HPAC mixtures. By integrating advanced analytical chemistry with contemporary toxicology, this issue aims to close the critical knowledge gaps necessary for effective risk assessment and regulation of these emerging persistent pollutants.

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.
