Special Issue Information

Dear Colleagues,

Emerging contaminants, including per- and polyfluoroalkyl substances (PFASs) and microplastics, are increasingly being detected at various concentrations in surface water. Therefore, there is concern that these compounds may have a negative impact on aquatic life and human health. This group also consists of pharmaceuticals, pesticides, industrial chemicals, surfactants, and personal care products that are consistently being found in groundwater, surface water, municipal wastewater, drinking water, and food sources. Moreover, these contaminants include endocrine-disrupting compounds, analgesics, antibiotics, hormones, and a whole range of other pharmaceutical compounds comprising anti-inflammatory, antidiabetic, and antiepileptic drugs.

At this juncture, it is important to not only identify the source and extent of these contaminants but also how to remediate them. Thus, this Special Issue will aim to find novel methods of identifying the fate and transport of these contaminants. Consequently, this Special Issue will seek publications on the remediation of these contaminants and their final disposal. This might involve state-of-the-art methods to destroy or immobilize these chemicals to prevent their further dispersal in the environment. The following subtopics are of special interest:

  • Fate and transport;
  • Advanced modeling and simulation techniques;
  • Advanced separation and destruction technologies;
  • Impact of water chemistry on remediation technologies;
  • Cost–benefit analysis for different remediation approaches.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.

Per- and polyfluoroalkyl substances (PFAS) are diverse synthetic chemicals manufactured over seven decades. It is an aliphatic molecule with a basic hydrophobic structure of carbon and fluorine linked to a hydrophilic end group. Due to their physicochemical properties associated with the unique structure, PFAS has been used in a wide variety of applications including aqueous film-forming foams (AFFF), paper, carpets, non-stick cookware, etc. as they make products resistant to water, heat, and stains. These molecules have drawn great attention recently for their unique properties, high stability and low degradability, and so-called “Forever Chemicals”. PFAS has the strongest carbon-fluorine bond which makes them persistent in the environment. Hence it contaminates natural resources and endangers public health. This review discusses the discovery, development, and evolution of PFAS from the wonder chemical era to a nightmare chemical era, exposure and its impacts on human health and the environment, current remediation techniques, and future trends of PFAS molecules and related products. The primary objective of this review is to identify knowledge gaps on PFAS contamination, remediation methods, and possible PFAS alternatives. Full article
