Analysis of per- and poly-fluoroalkyl substances (PFAS) in processed foods from FDA's Total Diet Study
31 Aug 2021 | Anal Bioanal Chem
PFAS features detected by LC-MS/MS correlated well in abundance with LC-IMS-MS data; however, LC-IMS-MS identified a number of additional PFAS, many known to be components of firefighting foams.
Early pregnancy loss: Do Per- and polyfluoroalkyl substances matter?
31 Aug 2021 | Environ Int
Overall, we suggest that most PFAS were not associated with early pregnancy loss at the current exposure levels.
Perfluorobutanoic acid (PFBA): No high-level accumulation in human lung and kidney tissue
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.
The occurrence of per- and polyfluoroalkyl substances (PFASs) in fluoropolymer raw materials and products made in China
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
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.
The Dilemma of Perfluorooctanoate (PFOA) Human Half-life
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
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.
Perfluoroalkyl substances (PFAS) in drinking water and risk for polycystic ovarian syndrome, uterine leiomyoma, and endometriosis: A Swedish cohort study
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.
Chlorinated polyfluoroalkyl ether sulfonic acids in fish, dust, drinking water and human serum: From external exposure to internal doses
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.
Removal of per- and poly-fluoroalkyl substances (PFASs) by wetlands: Prospects on plants, microbes and the interplay
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.
