Perfluorobutanoic acid (PFBA): No high-level accumulation in human lung and kidney tissue
Science
30 Aug 2021 | Int J Hyg Environ Health
Contrary to previous findings, analysis of short-chain PFAS in human lungs and kidney indicates PFBA is not likely to accumulate in these tissues.

[Op-Ed] Climate Change, Plastics, and Toxic Chemicals
News
27 Aug 2021 | The New York Times
The danger is that if we focus on only a single metric, like greenhouse gas emissions, we may unintentionally encourage the shift from fuel to plastics and chemicals that are also unsafe and unsustainable.

2nd Stakeholder Consultation on a Restriction for PFAS
Policy
25 Aug 2021
The competent authorities for REACH of the Netherlands, Germany, Denmark, Sweden, and Norway are currently preparing a REACH Annex XV Restriction Dossier for the group of PFAS since all these substances are considered to be persistent.

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.

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.

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.

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.

Maine PFAS Products Bill Most Far-Reaching To Date
Policy
18 Aug 2021
Maine passed what was touted as the most aggressive PFAS bill related to products thus far in the country.

Perfluorinated compounds disrupted osmoregulation in Oryzias melastigma during acclimation to hypoosmotic environment
Science
18 Aug 2021 | Ecotoxicol Environ Saf
PFOS showed a greater impact on fish’s ability to extract oxygen from fresh and saltwater than the shorter chain homolog PFBS.
