Special Issue Information
Dear Colleagues,
PFAS represent >4000 synthetic chemicals that usually consist of a hydrophobic and lipophilic fluorinated carbon chain and various types of hydrophilic end/head functional groups such as alcohol, carboxylate, sulfonamide, sulfonate, and phosphonates. Thanks to their unique properties as well as their high chemical and thermal stability, since the 1940s, PFAS have been manufactured in large quantities and widely used in a range of consumer, commercial, and industrial applications. In particular, PFAS are the active ingredients in aqueous film forming foam (AFFF), which, when mixed with water and discharged, can form an aqueous film that cuts off oxygen from fires. The carbon–fluorine bond in PFAS has a high dissociation energy and many PFAS are recalcitrant to both biotic and abiotic degradation. As a result of their widespread use, recalcitrant nature, and relatively high aqueous solubilities, PFAS are ubiquitous within the soil, groundwater, surface water, and biota. Human exposure to PFAS has been linked to health issues such as cancer, elevated cholesterol, obesity, immune suppression, and endocrine disruption. On April 10, 2024, EPA announced the final National Primary Drinking Water Regulation (NPDWR) for six PFAS. This Special Issue seeks research papers, including review articles, that elucidate (1) the occurrence, behavior, fate, and remediation of PFAS within the natural environment (e.g., soil and surface and groundwater); (2) treatment techniques for removing PFAS from both drinking water and wastewater; (3) human and ecological exposure to PFAS, ranging from molecular mechanisms of PFAS toxicity to epidemiological studies; and (4) the social and economic aspects of PFAS pollution, regulation, and remediation.

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. Environments 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 1800 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
