Childhood exposure to per-and polyfluoroalkyl substances during eating activities: Occurrence, exposure, and developmental risk
3 Nov 2025 | J. Environ. Chem. Ecotoxicol.
Children’s feeding bibs and tablecloths were found to contain multiple PFAS, including PFOA, PFNA, and PFOS. Modeled hand-to-mouth exposure during meals was estimated to approach or exceed safety thresholds for infants that potentially disrupt hormone and developmental pathways.
Associations between PFAS in public water system drinking water and serum among Southern California adults
30 Oct 2025 | J Expo Sci Environ Epidemiol
PFAS contamination in drinking water may be a significant contributor to adult serum PFAS levels, even among communities without high level contamination from industrial manufacturing.
Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in seafood from Thailand: Levels, geographic distribution, and risk from dietary exposure
27 Oct 2025 | Environ Monit Assess
Short-chain PFAS like PFBS and PFPeA were the most common contaminants found in Thai rivers and irrigation canals, showing that industrial discharge, agriculture, and urban runoff are spreading these persistent chemicals even into areas once considered clean.
Historical blood serum samples from Wilmington, North Carolina: The importance of ultrashort-chain per- and polyfluoroalkyl Substances
27 Oct 2025 | Environ Sci Technol
This study adds to the body of evidence that ultrashort-chain PFAS occur in high levels in people. Two ultrashort-chain PFAS were detected at high levels in almost every sample.
Association between maternal exposure to per-and polyfluoroalkyl substances and childhood growth trajectories up to 4 years of age: The Japan environment and children’s study
24 Oct 2025 | Environ Sci Technol
Maternal exposure to PFAS during pregnancy was linked to slower early childhood growth in Japan, with higher PFOS, PFOA, and PFHxS levels associated with lower weight gain and shorter height through age four, suggesting that prenatal PFAS exposure may hinder fetal and postnatal development.
Challenging assumptions: Per-and polyfluoroalkyl substances detected in deep groundwater across southeastern Australia
22 Oct 2025 | ACS ES&T Water
PFAS compounds were detected in deep groundwater across southeastern Australia, including aquifers over 100 meters deep, revealing that even supposedly protected water sources are vulnerable to contamination through surface infiltration, bore leakage, and long-range subsurface transport.
Life cycle assessment and life cycle costing analysis for removing per-and polyfluoroalkyl substances from landfill leachate with foam fractionation Technology
22 Oct 2025 | ACS ES&T Water
Foam fractionation was identified as a sustainable and cost-effective method for removing PFAS from landfill leachate, cutting global warming potential by more than half compared to traditional one-stage systems and producing minimal hazardous waste, though energy use and short-chain PFAS removal remain challenges.
Bioaccumulation, bioamplification, and elimination behavior of per- and polyfluoroalkyl substances during insect metamorphosis: Different strategies for silkworms and locusts
22 Oct 2025 | J Hazard Mater
Silkworms and locusts respond to PFAS exposure in very different ways during metamorphosis: silkworms absorb more PFAS but eliminate up to 39% through molting and metamorphic changes, while locusts absorb less and mainly excrete PFAS through feces, revealing species-specific strategies for coping with environmental pollution and its effects on development.
Concentrations of per-and polyfluoroalkyl substances (PFAS) in private well drinking water and serum of individuals exposed to PFAS through biosolids: The Maine Biosolids Study
20 Oct 2025 | Environ. Pollut.
Individuals living near farmland where PFAS-contaminated biosolids were historically applied had elevated PFAS in their private well water and blood, especially PFOA, which showed a strong water-to-serum correlation, demonstrating that biosolids can be a major exposure source and that some people may still have high serum levels even when their current water meets standards.
Evaluating environmental health communication: The readability of factsheets about per-and polyfluoroalkyl substances (PFAS)
20 Oct 2025 | Int. J. Hyg. Environ. Health.
Most PFAS factsheets published by government agencies are written at a college reading level, use too much complex language, and rarely include visuals or clear summaries, making them hard for the public to understand and showing the need for simpler wording, better design, and use of communication tools to improve readability.
Profiles of per- and polyfluoroalkyl substances in firefighter turnout gear and their impact on exposure assessment
20 Oct 2025 | Environ Sci Process Impacts
Firefighter turnout gear contains varying levels of PFAS chemicals that accumulate more in older gear and the inner moisture barrier, increasing with wear, heat, and abrasion, which raises firefighters’ potential exposure risks.
PFAS in bottled water from China: High prevalence of ultrashort-chain compounds, health risks, and global insights
19 Oct 2025 | J Hazard Mater
Bottled water across China contains high levels of ultrashort-chain PFAS such as TFA and PFPrA, highlighting growing global concerns and the need for stronger drinking water regulations.
Changes in the levels and predictors of per-and poly-fluoroalkyl substances in maternal plasma, relative to timelines of EPA PFOA Stewardship
18 Oct 2025 | Environ. Int.
PFOS, PFOA, PFHxS, PFHpS, and Me-PFOSA-AcOH declined over time after EPA’s PFOA Stewardship Program, but other PFAS such as PFNA, PFUnA, PFDeA, PFDoA, and GenX increased especially among non-White mothers, and higher levels were linked to eating fish/shellfish and vegetables, working, and having carpet or pets during pregnancy, showing that policies reduced some PFAS but exposure sources and inequities remain.
PFAS in stormwater control measures: Removal, distribution, and long-term fate
18 Oct 2025 | Water Research
Stormwater systems such as ponds and filters are not designed to remove PFAS, so most PFAS pass through the system, build up in water and sediment over time, and can transform from precursors into more toxic terminal PFAS, making stormwater a growing and often hidden source of PFAS pollution in the environment.
Emerging PFAS in Songbird Eggs from a Belgian Hotspot Site
17 Oct 2025 | Environ Res
Songbird eggs collected near a fluorochemical plant in Belgium contained record-high levels of both legacy and emerging PFAS, including newly detected compounds like SF5-PFSAs and ether-substituted PFAS, showing that PFAS continue to accumulate in wildlife and should be included in future monitoring and risk assessments.
