The occurrence of per- and polyfluoroalkyl substances (PFASs) in fluoropolymer raw materials and products made in China
Science
25 Aug 2021 | J Environ Sci (China)
Generally, the levels of PFOA in raw materials were higher than in products, implying that PFOA in the emulsion/dispersion resin could be partly removed during the polymerization or post-processing steps.

Occurrence of perfluoroalkyl substances (PFASs) in marine plastic litter from coastal areas of Central Chile
Science
25 Aug 2021 | Mar Pollut Bull
Long-chain PFAS, which can be metabolically degraded into PFOS, were found on six South American beaches in plastic debris.

External and internal human exposure to PFOA and HFPOs around a mega fluorochemical industrial park, China: Differences and implications
Science
25 Aug 2021 | Environ Int
PFAS were detected in human hair, and their compositions were similar to those in human serum, suggesting that hair is a good non-invasive indicator for long-term exposure to legacy long-chain perfluoroalkyl carboxylic acids and HFPOs.

Exposure to endocrine disrupting chemicals (EDCs) and cardiometabolic indices during pregnancy: The HOME Study
Science
25 Aug 2021 | Environ Int
HFPO-DA was found to potentially be a major problem of health risk that affects inflammation, gut barrier dysfunction, and gut microbiota disturbance in mammals.

Removal of per- and poly-fluoroalkyl substances (PFASs) by wetlands: Prospects on plants, microbes and the interplay
Science
25 Aug 2021 | Sci Total Environ
The choice of plants and bacterial species is however crucial for the bioremediation of PFAS, and the system efficiency relies on species-specific, sediment-specific, and pollutant-specific principles.

Chlorinated polyfluoroalkyl ether sulfonic acids in fish, dust, drinking water and human serum: From external exposure to internal doses
Science
25 Aug 2021 | Environ Int
The modeled serum concentrations of 6:2 Cl-PFESA were higher than its observed levels hinting at its gradually increasing exposure levels in the general population.

The Dilemma of Perfluorooctanoate (PFOA) Human Half-life
Science
25 Aug 2021 | Regul Toxicol Pharmacol
Based on information from both human observational studies and clinical data, we proposed a range for the half-life for PFOA of 0.5 to 1.5 years, which would likely raise many existing regulatory safe levels if all other parameters stayed the same.

Correlates of plasma concentrations of per- and poly-fluoroalkyl substances among reproductive-aged Black women
Science
24 Aug 2021 | Environ Res
PFAS exposure was strongly associated with reproductive factors such as reduced concentrations with parity, recent birth, lactation, and heavy menstrual bleeding in black women.
