The exposure of Czech firefighters to perfluoroalkyl substances and polycyclic aromatic hydrocarbons: CELSPAC - FIREexpo case-control human biomonitoring study
11 Apr 2023 | Sci Total Environ
Total PFAS blood levels in firefighters were higher than the control group and were mostly associated with the length of a firefighting career, age, blood donation, and population size.
Perfluorinated Compounds (PFCs) in River Waters of Central Italy: Monthly Variation and Ecological Risk Assessment (ERA)
6 Apr 2023 | Arch Environ Contam Toxicol
PFOS concentrations were classified as medium to high risk for the aquatic environment in all river samples, which also frequently contained PFBA, PFPeA, PFHxA, and PFOA, especially in summer months.
Practical Semiquantification Strategy for Estimating Suspect Per- and Polyfluoroalkyl Substance (PFAS) Concentrations

Development of a model PFAS calibration curve to determine the concentration of unknown or suspect PFAS.
Evaluating the Performance of Per- and Polyfluoroalkyl Substance Finishes on Upholstery Fabrics
3 Apr 2023 | AJOR
Superior stain performance for furniture textiles can be achieved through intentional material selection rather than PFAS treatments, which were shown to work only in limited situations.
Spatial and temporal variability of per- and polyfluoroalkyl substances (PFAS) in environmental media of a small pond: Toward an improved understanding of PFAS bioaccumulation in fish
1 Apr 2023 | Sci Total Environ
An analysis of surface water, sediment, and fish concentrations characterized the movement of PFAS in an entire pond.
Predictors of serum- per- and polyfluoroalkyl substance (PFAS) concentrations among infants in Guinea-Bissau, West Africa
1 Apr 2023 | Environ Res
Location of residence was an important determinant of PFAS concentrations in West African infants, which were generally lower than in most Western countries.
Per-and Polyfluoroalkyl Substances and Breastfeeding as a Vulnerable Function: A Systematic Review of Epidemiological Studies
29 Mar 2023 | Toxics
This review found that PFOS, PFOA, and PFNA maternal exposure levels were consistently associated with shorter total breastfeeding duration.
Per-and Polyfluoroalkyl Substances in Canadian Fast Food Packaging
28 Mar 2023 | Environ. Sci. Technol. Lett.
The use of PFAS in food packaging such as “compostable” bowls represents a regrettable substitution of single-use plastic food packaging.
The universe of fluorinated polymers and polymeric substances and potential environmental impacts and concerns
27 Mar 2023 | Curr. Opin. Green Sustain. Chem.
The authors suggest that action is needed to address the lack of understanding on polymeric PFAS, but point out that fluoropolymers have already resulted in widespread contamination from their production, manufacturing, and use.
Exposure to perfluoroalkyl substances and women's fertility outcomes in a Singaporean population-based preconception cohort
27 Mar 2023 | Sci. Total Environ.
Higher PFAS exposures were associated with decreased fertility in women, especially for PFDA.
Per- and polyfluoroalkyl substances (PFAS) registered under REACH—What can we learn from the submitted data and how important will mobility be in PFAS hazard assessment?
27 Mar 2023 | Sci. Total Environ.
Due to lack of data, many PFAS registered under REACH have not been identified as persistent, bioaccumulative, and toxic, but still have undesirable properties such as persistence, toxicity, bioaccumulative, and mobile.
Characterization of PFAS Air Emissions from Thermal Application of Fluoropolymer Dispersions on Fabrics
27 Mar 2023 | J Air Waste Manag Assoc
This study reported nontargeted PFAS emission characterization, real-time analyses, and the quantification of 30 volatile targets PFAS from the thermal application of fluoropolymers on fabrics.
Association between early-childhood exposure to perfluoroalkyl substances and ADHD symptoms: A prospective cohort study
25 Mar 2023 | Sci. Total Environ.
Toddlers exposed to moderate levels of PFAS had a higher likelihood of exhibiting ADHD traits at eight years of age.
PFAS: forever chemicals—persistent, bioaccumulative and mobile. Reviewing the status and the need for their phase out and remediation of contaminated sites
23 Mar 2023 | ESEU
The authors of this review conclude that substituting individual PFAS recognized as hazardous with other possibly equally hazardous PFAS with virtually unknown chronic toxicity should not be a solution.
A review of cardiovascular effects and underlying mechanisms of legacy and emerging per-and polyfluoroalkyl substances (PFAS)
22 Mar 2023 | Arch Toxicol
Various emerging alternatives to legacy PFAS also play increasingly prominent toxic roles in heart and circulation health that are milder, similar to, or more severe than legacy PFAS.
