Early pregnancy loss: Do Per- and polyfluoroalkyl substances matter?
Science
31 Aug 2021 | Environ Int
Overall, we suggest that most PFAS were not associated with early pregnancy loss at the current exposure levels.

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.

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.

Perfluoroalkyl substances (PFAS) in drinking water and risk for polycystic ovarian syndrome, uterine leiomyoma, and endometriosis: A Swedish cohort study
Science
25 Aug 2021 | Environ Int
Exposure to high levels of PFAS in drinking water was associated with an increased risk of enlarged and irritated ovaries.

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.

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.
