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.

Childhood exposure to per-and polyfluoroalkyl substances in educational environments: Arising from stationery and implications for health
Science
15 Dec 2025 | J. Environ. Chem. Ecotoxicol.
Several products purchased in China released measurable PFAS including precursors that increased after oxidation and maximum estimated intake from hand to mouth contact with some pen grips approaching the European Food Safety Authority tolerable intake for children.

Nationwide occurrence and flux estimates of PFAS in leachate from waste-to-energy sector: An emerging reservoir linked to short-term waste storage
Science
25 Nov 2025 | Water Res
Chinese municipal solid waste incinerators leachates may act as a concentrated source of short-chain PFAS, particularly PFBA and PFBS, although membrane treatment removes most PFAS, the persistence or even increase of compounds like GenX suggests potential limitations that are important for environmental monitoring and policy decisions.

PFAS-induced immunotoxicity in freshwater fish of inland China: mechanisms and ecological risks
Science
10 Nov 2025 | Comp. Biochem. Physiol. C
PFAS are widespread in China’s freshwater systems, where long-chain and sulfonic types result in suppressed immune responses and higher infection risk. These effects worsen with co-exposure to heavy metals and microplastics.

Associations between per- and polyfluoroalkyl substances and reproductive outcomes among women undergoing in vitro fertilization/intracytoplasmic sperm injection treatment
Science
10 Nov 2025 | Reprod Toxicol
Mixed exposure to long-chain PFAS and emerging chlorinated PFESAs in infertile Chinese women was associated with increased risk of infertility.

PFAS in bottled water from China: High prevalence of ultrashort-chain compounds, health risks, and global insights
Science
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.

Short-chain PFAS predominate in large-scale lithium battery industrial parks, Eastern China: Source apportionment and downstream impact implications
Science
25 Sep 2025 | J. Hazard. Mater.
Lithium battery industrial parks in eastern China release significant amounts of short-chain PFAS into rivers, with urban wastewater, traditional industries, and the battery industry each contributing about one-third of the pollution, leading to ecological risks, in downstream ecosystems.

A geospatial dataset of PFOS and PFOA occurrence records in China’s multi-media environments
Science
8 Sep 2025 | Nature
PFOS and PFOA, were found widely across China’s water, soil, air, food, and living organisms between 2021 and 2024, with the new geospatial dataset revealing pollution hotspots and recent declines in human blood levels linked to stricter regulations.

Co-occurrence behaviors of per- and polyfluoroalkyl substances (PFASs) and heavy metals in the groundwater of dyeing industrial sites in southern China
Science
27 Aug 2025 | Ecotoxicol Environ Saf
Groundwater beneath long-operating dyeing industrial sites in southern China is heavily contaminated with both PFAS and toxic heavy metals, with concentrations varying by season and site, highlighting serious risks to water safety and the need for integrated pollution control.

Per-and polyfluoroalkyl substances on the surface of children's feeding smocks: High-throughput characterization and implications for exposure assessment
Science
11 Aug 2025
Elevated PFAS levels were detected on Chinese children’s feeding smocks, making routine hand-to-mouth contact during use a potential exposure at levels on par with everyday exposure from indoor dust and air.

Legacy and novel per-and polyfluoroalkyl substances in tap water from East China: Impact from water sources and risk mitigation by household purifiers
Science
5 Aug 2025 | Environ. Sci. Technol.
While some home water purifiers removed a portion of PFAS from tap water, none eliminated them completely, and removal efficiency varied widely depending on the device type and specific PFAS compound.

Association of serum per-and polyfluoroalkyl substances exposure with leukocyte telomere length in Chinese middle-aged and older adults: Role of genetic susceptibility and healthy diet
Science
16 Jul 2025 | Environ Sci Technol
In nearly 1,500 middle-aged and older Chinese adults, higher blood levels of the PFDA and PFUDA were linked to noticeably shorter telomeres, with the greatest shrinkage in people who also carried aging-related genes and ate a low-quality diet, suggesting these chemicals may speed biological aging.

Association between prenatal exposure to per-and polyfluoroalkyl substances and blood pressure among preschool-aged children: The moderating effect of child-age and the mediating effect of inflammatory cytokine
Science
5 Jul 2025 | Ecotoxicol Environ Saf
Tracking 215 mother-child pairs in China, researchers found that prenatal exposure to common PFAS chemicals was associated with higher diastolic blood pressure in preschoolers, and that inflammatory signals in cord blood partly explained the effect, pointing to a subtle early-life pathway by which PFAS may increase the likelihood of later heart-disease risk.

Per- and polyfluoroalkyl substances, genetic factors, and sleep health in reproductive-aged women: a cross-sectional study of the Shanghai Birth Cohort.
Science
30 Jun 2025 | Environ Int
A Shanghai study of nearly 1,000 women found that higher blood levels of PFAS, particularly newer chlorinated alternatives and PFOS isomers, were linked to increased snoring, with genetics magnifying the risk.
