Concentrations of perfluoroalkyl substances in the dust of Japanese households and buildings; Implications for human exposure
1 Jun 2026 | Atmos. Pollut. Res.
PFOS, PFOA, and PFNA remain persistent in indoor dust despite phaseouts, with campus and public buildings containing more than 16x higher PFAS concentrations than household dust.
The cost of “forever”: Economic implications of per-and polyfluoroalkyl substances (PFAS) mitigation in drinking water and their impact on water affordability
27 May 2026 | ACS ES&T Water
PFAS mitigation models in California suggest household water bills could rise by about $58 per month under the strictest scenario, with the greatest affordability burden falling on groundwater-dependent and lower-income communities, where water costs may exceed the 2.5% income threshold.
Environmental health literacy in American Indian communities: Evaluating per-and polyfluoroalkyl substance (PFAS) educational materials
26 May 2026 | Environments
Most publicly available PFAS educational materials were found to be too advanced, not actionable, and often culturally mismatched for indigenous communities, limiting their usefulness to reduce PFAS exposure.
Environmental exposure to emerging per‐and polyfluoroalkyl substances and cardiovascular diseases: A mixture analysis
26 May 2026 | Health Science Reports
An NHANES 2015-2020 mixture analysis found that higher serum PFAS exposure, especially PFOA, PFNA, ME-PFOSA-AcOH, was associated with higher risk of cardiovascular impairments such as heart attack, congestive heart failure, coronary heart disease, and stroke while higher combined PFAS exposure was associated with increased odds of all evaluated cardiovascular outcomes.
Notable impact of urban ventilation corridors on the transport of particle-bound ultrashort-chain perfluoroalkyl substances in the atmosphere
26 May 2026 | J. Hazard. Mater.
In Beijing, China, PFAS were found attached to tiny air pollution particles throughout the city, especially during colder months, with urban wind corridors appearing to carry these chemicals through the air rather than simply clearing pollution away.
Longitudinal trends of per-and polyfluoroalkyl substances in Chinese children from birth to 7 years of age
22 May 2026 | Environ Int
Breastfeeding was linked to higher PFAS levels, especially at age 2; higher BMI and suburban residence were associated with higher concentrations; and higher parental education was associated with lower PFAS levels.
PFAS exposure induces hearing loss by targeting cochlear hair cells and spiral ganglion neurons
21 May 2026 | Sci Rep
PFAS exposure in mice was linked to hearing loss because it damaged key cells in the inner ear that help detect sound and send sound signals to the brain.
PFAS contamination in agricultural systems near an active war zone: Sources, distribution, and crop uptake
20 May 2026 | J. Hazard. Mater.
In the Middle East, PFAS were found in soil and potato plants near an active war zone; farming practices likely explained much of the soil contamination, while contaminated leaves may point to PFAS pollution moving through the air from conflict activity or regional air pollution.
Analysis of ultrashort per-and polyfluoroalkyl substances (PFAS) in fruits and vegetables
19 May 2026 | J. Agric. Food Chem.
TFA, an ultrashort PFAS, was found in all 103 fruit and vegetable samples tested in the U.S. with the estimated daily exposure from these foods below the European Food Safety Authority’s acceptable daily intake level.
Occurrence of ultrashort-chain per-and polyfluoroalkyl substances in the coral reef ecosystem of the Beibu Gulf, South China Sea
15 May 2026 | Environ. Sci. Technol. Lett.
Ultrashort PFAS, especially TFA, were widely found in reef-building corals, suggesting these highly mobile chemicals can accumulate in coral ecosystems and be linked to hazards such as algal growth inhibition and toxicity concerns for aquatic organisms.
Per- and polyfluoroalkyl substances in e-waste dust
13 May 2026 | Environ Sci Process Impacts
Dust from Canadian recycling facilities contained many PFAS, especially polyfluoroalkyl phosphate esters, fluorotelomer alcohols, ultrashort PFAS, PFOA, and PFOS, suggesting that workers may face exposure risks and that electronics recycling can release these pollutants into the environment.
Comprehensive per-and polyfluorinated substances profiling in beverages: Simultaneous quantification of ultrashort-chain to long-chain compounds in ready-to-drink teas and fruit juices
11 May 2026 | Toxics
Ready-to-drink teas and fruit juices bought from a local Pennsylvania grocery store contained mainly ultrashort-chain PFAS, especially TFA, TFMS, PFPrA, and PFPrS, with some short-chain PFAS also detected.
Fluorine mass balance exposes intrinsic PFAS and precursor content in geosynthetics used in landfill systems
11 May 2026 | Environ. Pollut.
Geosynthetic landfill materials contain PFAS including ultra-short-chain compounds such as PFPrA and TFA, along with PFBS and fluorotelomer-related species, while over 80% of fluorinated content remains unidentified, indicating these materials may act as overlooked long-term PFAS sources and that conventional monitoring substantially underestimates total PFAS inventories.
Advancing PFAS biomonitoring in hair: Rapid analytical method and global comparison of US exposure
10 May 2026 | Drug Test. Anal.
PFHpA was detected in every New York hair sample tested, while PFOA and PFNA appeared less often. This analytical technique may help track longer-term PFAS exposure and regional differences in contamination patterns.
Lipid metabolism links seminal PFAS exposure to IVF outcomes
9 May 2026 | Environ Int
In a study of 132 men undergoing IVF (in vitro fertilization) treatment in China, higher levels of several PFAS in semen were associated with fewer high-quality embryos—changes in fat-related biological pathways offer one possible explanation.
