Prenatal exposure to per-and polyfluoroalkyl substances and its association with Developmental Defects of Enamel (DDE) and dental caries in 4 years old children: Findings from Shanghai birth cohort
14 Apr 2025 | Environ. Int.
Prenatal exposure to PFBS was linked to a higher risk of developmental dental enamel defects, while PFHpA was associated with a lower risk, highlighting distinct effects of short-chain PFAS on enamel formation in children.
Effectiveness of pitcher and bottle filters to remove poly-and perfluoroalkyl substances (PFAS) from drinking water
14 Apr 2025 | Sci. Total Environ.
Out of 17 pitcher and bottle filters tested, only five reduced PFAS levels below the EU’s 100 ng/L limit, with the top filters removing up to 98% of total PFAS and over 97% of emerging PFAS, showing that removal efficiency increased with PFAS chain length and was highest in filters with large surface areas and micropore volumes.
DRAFT Third Report of the Independent PFAS Scientific Advisory Panel for Jersey – Testing, biomonitoring and management of PFAS in the human body
8 Apr 2025
This report is the third in a series produced by the Independent PFAS Scientific Advisory Panel for Jersey. It focuses on the testing, biomonitoring, and management of PFAS in the human body.
Obtaining and evaluating information on the use, release, and health effects of two types of long-chain PFAS used as alternatives for legacy long-chain perfluoroalkyl acids: a case study.
8 Apr 2025 | Environ Health Perspect
Two long-chain PFAS used at a New Jersey fluoropolymer facility, were found to be as bioaccumulative and toxic as phased-out long-chain PFAAs they have replaced, with human half-lives of several years and health effects observed in both animals and exposed workers.
PFAS regulations and economic impact: A review of U.S. pulp & paper and textiles industries
8 Apr 2025 | Chemosphere
The pulp, paper, and textiles industries face financial risks from PFAS pollution, including treatment costs projected at $3 billion annually, product bans, recycling disruptions, and lawsuits like an $11.9 million paper mill settlement, all due to widespread emissions, contamination, and lack of PFAS-specific regulations.
PFAS insights: A review of historical data, environmental applications, health effects, and pollution challenges in Pakistan
7 Apr 2025 | Environ. Sci. Policy
Untreated industrial waste in Pakistan has led to widespread PFAS contamination in rivers, fish, and drinking water, posing risks to public health, while limited regulations and weak enforcement hinder effective response.
Determinants of plasma poly-and perfluoroalkyl substances during pregnancy: The Japan environment and children’s study
1 Apr 2025 | Ecotoxicol. Environ. Saf
In a study of 103,099 pregnant women in Japan, researchers found that PFAS levels in blood varied most by region, with higher levels linked to certain areas, older age, higher fish intake, and socioeconomic status—highlighting both geographic and personal factors driving exposure to these toxic chemicals.
Per-and polyfluoroalkyl ether acid (PFEA) concentrations in indoor dust are higher in homes closer to a fluorochemical manufacturing facility
31 Mar 2025 | Environ. Sci. Technol.
Homes closer to a PFAS manufacturing facility in North Carolina had significantly higher levels of toxic PFAS—including GenX and Nafion byproducts—in indoor dust, suggesting that air emissions from the facility may be a major source of exposure, especially for children.
Contaminations from lithium-ion battery fires—per-and polyfluoroalkyl substances (PFAS) in soot
26 Mar 2025 | Fire Technology
Fires involving lithium-ion batteries release significant amounts of toxic PFAS chemicals into soot, with higher temperatures causing greater emissions—raising urgent concerns for environmental safety and battery recycling.
Serum concentrations of per-and polyfluoroalkyl substances (PFAS) among men from the Danish fire services and Armed Forces
25 Mar 2025 | Int. J. Hyg. Environ.
Civilian airport firefighters in Denmark showed slightly elevated blood levels of PFAS chemicals such as PFHxS, PFHpS, and PFOS—commonly found in firefighting foams—pointing to the need for stronger regulations and safer, non-toxic alternatives.
Elevated PFAS precursors in septage and residential pump stations
25 Mar 2025 | Environ. Sci. Technol. Lett.
Septic systems and residential pump stations—despite lacking industrial input—were found to be significant sources of PFAS contamination, with septic systems showing especially high levels of PFAS precursors like diPAPs, underscoring the need to include precursor analysis in monitoring and to strengthen wastewater treatment strategies for decentralized systems.
Non-metal roofing materials as potential sources for pollutants-laboratory leaching studies on various roofing materials
24 Mar 2025 | J. Hazard. Mater.
PFAS were detected in leachate from several common non-metal roofing materials—such as fiber cement and bitumen shingles—indicating that rooftops may be an overlooked source of PFAS pollution in urban stormwater runoff.
An overview of potential alternatives for the multiple uses of per-and polyfluoroalkyl substances
24 Mar 2025 | Environ. Sci. Technol.
40 out of 325 known PFAS applications have safer and effective alternatives already available. However, no alternatives were yet identified for 83 uses.
Suspect screening of per- and polyfluoroalkyl substances in new firefighter turnout gear textiles
