Special Issue Information
Dear Colleagues,
Halogenated and heterocyclic derivatives of polycyclic aromatic compounds, which include halogenated polycyclic aromatic hydrocarbons (HPAHs), polycyclic aromatic nitrogen heterocycles (PANHs), polycyclic aromatic sulfur heterocycles (PASHs), polycyclic aromatic oxygen heterocycles (PAOHs), and halogenated heterocyclic compounds, represent a critical, yet under-investigated, class of environmental contaminants. Unlike their well-studied parent compounds, these compounds 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 profiles of these different polycyclic aromatic compounds. 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 these organic 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 250 words) can be sent to the Editorial Office for assessment.
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.
