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.

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.
