Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in seafood from Thailand: Levels, geographic distribution, and risk from dietary exposure
Science
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.

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
Science
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.

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.

Levels of serum per- and polyfluoroalkyl substances and association with dyslipidemia in the Korean population
Science
7 Jul 2025 | Ecotoxicol Environ Saf
A large national study of nearly 3,000 Korean adults found widespread PFAS exposure and showed that higher serum concentrations of several compounds, especially PFOA, PFHxS, PFNA and PFDeA, were consistently associated with elevated low-density lipoprotein cholesterol and total cholesterol, implying potential cardiovascular risk and reinforcing the need for stricter regulation.

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.

Association between exposure to bisphenols and per- and polyfluoroalkyl substances and behavioral problems among Chinese preschoolers
Science
23 Jun 2025 | Ecotoxicol Environ Saf
A study of 823 Chinese preschoolers found that children with higher combined urine levels of certain BPA-replacement plastics and PFHxS were about twice as likely to show behaviour issues, including hyperactivity, anxiety and conduct problems, highlighting that these may be regrettable substitutes.
