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.

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.

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.
