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.

Heavier sediment pollution by per-and polyfluoroalkyl substances (PFASs) in tropical coasts compared to temperate regions: An overlooked hotspot
Science
14 Jun 2025 | J. Environ. Sci.
Sediments along a tropical Chinese coastline contain markedly higher levels of both legacy and emerging PFAS, reaching about 13 ng/g dry weight and dominated by mid-chain compounds such as PFHxA and 9H-PFNA, a concentration exceeding those typically reported for temperate regions; researchers trace the pollution to land-based runoff, rocket-launch fallout, and other local sources.

National Assessment of PFAS in Landfill Leachate in China: Non-Negligible Ultrashort-Chain Components and Socioeconomic Impacts
Science
20 May 2025 | Environ Sci Technol
A nationwide survey of 70 Chinese landfills found that their wastewater holds sizable amounts of PFAS, mostly newer ultrashort‑chain chemicals, releasing about 419 kg into the environment each year and underscoring the need for stricter waste controls.

Identification and environmental occurrence of novel per- and polyfluoroalkyl substances derived from lithium-ion battery
Science
18 May 2025 | Water Res
Water and sediment near lithium‑ion battery factories and recycling sites in China contain 33 different PFAS chemicals, including seven never documented before, revealing that battery production and recycling can release highly mobile short‑chain PFAS that may endanger ecosystems and human health.

Incidence of respiratory diseases associated with per-and polyfluoroalkyl substances (PFAS) in PM2. 5: New evidence from a population-based survey of Pearl River Delta (PRD), China
Science
12 May 2025 | J. Hazard. Mater.
A large-scale study in China found that exposure to PFAS chemicals in fine particulate air pollution (PM2.5) was strongly associated with increased rates of respiratory diseases—such as asthma, cough, and rhinitis—in children and adolescents, highlighting PFAS in air as an underrecognized but serious health risk.

Atmospheric emission of per-and polyfluoroalkyl substances (PFAS) from a fluoropolymer manufacturing facility: Focus on emerging PFAS and the potential contribution of condensable PFAS on their atmospheric partitioning
Science
12 May 2025 | Environ. Sci. Technol.
A major fluoropolymer manufacturing facility in China was found to emit dozens of previously undetected PFAS—including emerging compounds like Cl-PFECAs and multi-head PFESs—into the air and surrounding environment, raising concern about widespread contamination and the need for stronger oversight of industrial PFAS emissions.

High-resolution mass spectrometry for identification, quantification, and risk assessment of 40 PFAS migrating from microwave popcorn bags
Science
29 Apr 2025 | Molecules
A pilot study found a small sampling of Chinese microwave popcorn bags released dozens of PFAS into food, and although standard tests suggest low risk, a more comprehensive assessment reveals combined exposures could surpass health guidelines, highlighting the need for stricter regulation.

Unraveling the Exposure Spectrum of PFAS in Fluorochemical Occupational Workers: Structural Diversity, Temporal Trends, and Risk Prioritization
Science
18 Mar 2025 | Environ Sci Technol
Researchers analyzed the blood of fluorochemical plant workers in China and found 64 types of PFAS chemicals—including 15 previously unknown ones—with some linked to high health risks due to their persistence and ability to accumulate in the body, highlighting the need for stricter monitoring and regulation of these toxic substances.

The stubborn “chemical invader”: Challenges and solutions for per-and polyfluoroalkyl substances (PFAS) in Chinese sewage sludge
Science
17 Feb 2025 | ACS EST Water
Sewage sludge in China acts as both a source and sink for PFAS, with compounds like PFOS accumulating due to limited degradation by conventional wastewater treatments, highlighting the need for innovative extraction, detection, and environmentally sustainable removal methods to reduce associated environmental contamination and health risks.

Investigation of common and unreported parabens alongside other plastic-related contaminants in human milk using non-targeted strategies
Science
6 Feb 2025 | Chemosphere
A study of human milk in Canada and South Africa detected multiple paraben-related contaminants, including restricted and uncommon ones, as well as a tire-related chemical, PFAS, and phthalate metabolites. The results emphasize the need to utilize non-target analysis as well as further research the usage, biotransformation, and potential toxicity of a number of contaminants.

Emerging PFAS Exposure Is More Potent in Altering Childhood Lipid Levels Mediated by Mitochondrial DNA Copy Number
Science
3 Feb 2025 | Environ Sci Technol
Exposure to emerging PFAS, such as 6:2 Cl-PFESA, PFO4DA, and PFO5DoDA, is linked to higher triglycerides, total cholesterol, and low-density lipoproteins in Chinese children aged 7–10 years, suggesting an increased risk of metabolic disorders, including obesity, cardiovascular diseases, and diabetes.
