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.

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.

Quantitative Associations of Per- and Polyfluoroalkyl Substances in Segmented Hair with Serum and Dust: Potential of Hair as a Retrospective Biomarker
Science
23 Feb 2026 | Environ Sci Technol
In a two-year panel of female e-waste workers, concentrations of long-chain perfluorosulfonic acids in segmented hair were positively associated with corresponding average serum levels over matched prior months, suggesting hair may retrospectively reflect internal exposure, while short-chain PFAS showed weaker or inconsistent relationships.

Tracking PFAS across environmental media surrounding fluorochemical industrial park: Insights from nontarget analysis and risk assessment
Science
7 Feb 2026 | Environ. Sci. Technol.
A fluorochemical industrial park in Zhejiang, China identified 112 PFAS across water, sediment, and soil, many of them emerging compounds that may pose ecological and human health risks comparable to or greater than legacy substances, suggesting emissions could contribute to complex and undercharacterized contamination profiles not fully addressed by current monitoring frameworks.

Whales contribute to novel insight on poly-and perfluoroalkyl substances bioaccumulation in the East China Sea
Science
19 Jan 2026 | Environ. Pollut.
PFAS including long-chain perfluoroalkyl carboxylates and the PFOS substitute 6:2 Cl-PFESA were widely detected across multiple whale species and tissues from the East China Sea, with species- and tissue-specific accumulation patterns suggesting that PFAS exposure and bioaccumulation may be underestimated or biased when marine monitoring relies on a single bioindicator species.

The occurrence, sources, and health risks of per-and polyfluoroalkyl substances (PFAS) in pm 2. 5 in Shihezi, a typical inland arid industrial city
Science
19 Jan 2026 | Atmos. Pollut. Res.
PFAS were widely detected in fine particulate air pollution in an arid industrial city, dominated by short chain compounds linked to industrial emissions and atmospheric transformation, suggesting that airborne PFAS exposure may be underestimated when total human exposure, particularly for children.
