Concentrations of perfluoroalkyl substances in the dust of Japanese households and buildings; Implications for human exposure
Science
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.

Notable impact of urban ventilation corridors on the transport of particle-bound ultrashort-chain perfluoroalkyl substances in the atmosphere
Science
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
Science
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.

Occurrence of ultrashort-chain per-and polyfluoroalkyl substances in the coral reef ecosystem of the Beibu Gulf, South China Sea
Science
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.

Lipid metabolism links seminal PFAS exposure to IVF outcomes
Science
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.

PFAS exposure perturbs lipid metabolism to promote gestational diabetes mellitus and alter growth trajectories via distinct mechanisms in singletons and twins
Science
3 May 2026 | Environ Sci Technol
PFAS exposure increased gestational diabetes risk in both single-baby pregnancies and twins, while twins showed a stronger mixture effect driven mainly by PFNA and emerging PFAS (e.g., HFPO-DA) with bile acid–related pathways, while single-baby pregnancies were more influenced by PFOA through broader lipid and amino acid metabolism disruptions.

Co-occurrence, bioaccumulation, and dietary risk assessment of per-and polyfluoroalkyl substances and heavy metals in rice
Science
14 Apr 2026 | J Agric Food Chem
Rice grown near a Chinese industrial area was found to accumulate multiple PFAS, including emerging compounds such as HFPO-DA, alongside heavy metals through both soil and irrigation water pathways, with evidence of transfer into edible grains and dietary exposures that may exceed U.S. health-based thresholds.

Okinawa town finds elevated PFAS levels near Marine base in annual water survey
News
9 Apr 2026 | Stars and Stripes
Three sites near the Ryukyu Hospital showed the highest PFAS levels, including 220 parts per trillion upstream of the hospital, 200 parts per trillion downstream and 130 parts per trillion where streams merged, according to the survey results.

Alarming pet food study is causing great concern among dog and cat owners
News
3 Apr 2026 | Earth.com
Across 100 products sold in Japan, the team screened 34 PFAS and found contamination across dog and cat foods alike, mainly from contaminated fish ingredients.

Distribution and concentration of airborne per-and polyfluoroalkyl substances (PFAS) in indoor and outdoor environments: A systematic review
Science
1 Apr 2026 | Saf Health Work
Airborne PFAS, including fluorotelomer alcohols, perfluoroalkyl carboxylic acids, and perfluoroalkyl sulfonic acids, are found at higher levels indoors and in occupational settings than outdoors.

Contamination profiles of legacy and emerging per-and polyfluoroalkyl substances in various vegetable oils collected in Chinese markets
Science
17 Mar 2026 | J. Environ. Sci.
Several common vegetable oils sold in Chinese markets, including soybean, rapeseed, sesame, sunflower, peanut, flaxseed, rice bran, corn germ, camellia, tea seed, and blended oils, were found to contain legacy PFAS such as PFOA and PFOS and emerging compounds including 6:2 FTS and GenX, with contamination patterns suggesting links to refining processes, packaging, or contaminated crops.

Exploring per-and polyfluoroalkyl substances exposure risk in indoor air and PM2. 5: Correlations with respiratory health in university environments
Science
9 Mar 2026 | Env. Poll.
Indoor air and PM2.5 in university environments contained PFAS such as PFPeA, PFOA, PFOcDA, PFHxDA, and PFOS that were also detected in students’ exhaled breath condensate, suggesting inhalation exposure may be linked to respiratory inflammatory responses, though estimated exposure risk was low and results are based on limited observational correlations.

Characterizing per-and polyfluoroalkyl substances (PFAS) exposure in petrochemical workers: Insights from paired blood and urine samples
Science
9 Mar 2026 | Molecules
PFAS exposure in petrochemical workers is elevated relative to the general population but lower than highly exposed industries, with PFOA dominating blood burdens, PFPeA dominating urine, long-chain PFAS accumulating in blood while short-chain PFAS are preferentially excreted, and cumulative exposure primarily driven by years of occupational service.

Integrating target, nontarget analysis with machine learning to illuminate PFAS characteristics and health risks in Chinese cosmetics
Science
7 Mar 2026 | Environ Pollut
Analysis of commonly used Chinese cosmetics including face creams, lotions, sunscreen, mascara, eyeshadow, foundation, antiperspirant, shampoo, and facial wash detected multiple PFAS, including PFOA, PFNA, PFBS, PFHxS, and fluorotelomer sulfonates, with risk estimates suggesting dermal exposure from some items may exceed Texas safety thresholds.

Diet and everyday product use and serum per-and polyfluoroalkyl substances levels in the Korean population: Findings from the Korean national environmental health survey
Science
23 Feb 2026 | Environ. Res.
Higher serum PFAS levels were most strongly associated with seafood intake, especially fish and shellfish, and with use of food contact materials such as disposable paper cups, plastic pouches, and coated cookware, while a distinct pattern suggested PFHxS may be more closely linked to fast food consumption and personal care or household products.
