Interface hydrogen bonding dominated perfluorooctanoic acid (PFOA) accumulation by iron particles in drinking water pipes
8 Nov 2022 | Chemosphere
Old unlined drinking water pipes had a higher accumulation capacity for PFOA than new pipes due to the accumulation of some iron particles.
Organic Fluorine as an Indicator of Per- and Polyfluoroalkyl Substances in Dust from Buildings with Healthier versus Conventional Materials
4 Nov 2022 | Environ Sci Technol
Classrooms renovated with “healthier” furniture and carpeting reported to be PFAS-free had on average 66% less PFAS and 49% less extractable organic fluorine levels in dust compared to conventional rooms, demonstrating that materials solutions reduce the accumulation of PFAS within buildings.
Treatment technologies for removal of per-and polyfluoroalkyl substances (PFAS) in biosolids
2 Nov 2022 | J. Chem. Eng.
Different PFAS destruction technologies such as incineration, hydrothermal liquefaction, pyrolysis, thermal hydrolysis, supercritical water oxidation, and several other processes, are discussed in this review.
Developing an Exposure Burden Score for Chemical Mixtures Using Item Response Theory, with Applications to PFAS Mixtures
2 Nov 2022 | Environ Health Perspect
A novel exposure burden score method for chemical mixtures was developed and applied to estimate the exposure burden of PFAS mixtures and resulted in stronger estimated associations with cardio-metabolic outcomes in the general U.S. population compared to summed PFAS concentrations.
The effects of perfluoroalkyl and polyfluoroalkyl substances on female fertility: A systematic review and meta-analysis
2 Nov 2022 | Environ Res
Increased levels of PFAS exposure are associated with reduced female fertility, which should be taken into account for risk assessments of manufacturing products containing PFAS.
Exposure to per- and polyfluoroalkyl substances and glycemic control in older US adults with type 2 diabetes mellitus
2 Nov 2022 | Environ Res
In older US adults with known type 2 diabetes, poor glycemic control is more likely to be observed in those with high serum levels of PFNA & PFHxS and PFDeA in men.
Longitudinal measurements of per-and poly-fluoroalkyl substances (PFAS) in archived human serum samples between 1975 and 1995 in Australia
1 Nov 2022 | J. Hazard. Mater.
Repeat serum samples collected from 17 participants in 1975, 1981 and 1995 were analyzed for 35 PFAS, revealing increasing detection frequencies over time and a 7-fold increase in median summed PFAS concentrations from 1975 to 1995.
What do we know about the production and release of persistent organic pollutants in the global environment?
26 Oct 2022 | Environ. Sci. Adv.
The U.S. has the highest cumulative environmental releases of PFOS, whereas Europe has the highest cumulative environmental releases of PFOA.
Maternal Offloading of Per-and Polyfluoroalkyl Substances to Eggs by Lake Michigan Salmonids
25 Oct 2022 | ES&T
Salmon can bioaccumulate and offload PFAS to embryos, which has implications for embryo health, egg predation by wildlife, and ultimately human exposure.
PFAS and Precursor Bioaccumulation in Freshwater Recreational Fish: Implications for Fish Advisories
24 Oct 2022 | Environ Sci Technol
PFAS precursors were found to have higher bioaccumulation potentials than PFAS commonly considered in regulatory efforts, suggesting that more comprehensive fish advisories are needed to prevent human exposures.
[Commentary] Improving governance of “forever chemicals” in the US and beyond
21 Oct 2022 | One Earth
Dramatically reducing PFAS production, use, and exposure requires innovative governance interventions, proactive and conscientious business actions, and scientific advances that defy disciplinary boundaries, all guided by the voices, experiences, and needs of impacted communities.
Blood Concentrations of Per-and Polyfluoroalkyl Substances are Associated with Autoimmune-like Effects in American Alligators from Wilmington, North Carolina
20 Oct 2022 | Frontiers in Toxicology
PFAS was found to broadly alter immune activities resulting in autoimmune-like diseases in American alligators.
Prenatal exposure to perfluorooctane sulfonate alternatives and associations with neonatal thyroid stimulating hormone concentration: A birth cohort study
20 Oct 2022 | Chemosphere
Higher concentrations of prenatal PFBS was associated with lower developmental hormone concentrations in newborns.
[Perspective] EPA Takes Action Against Harmful "Forever Chemicals" in the US Water Supply
19 Oct 2022 | JAMA
This Medical News article discusses new EPA advisories for PFAS as well as new National Academies guidance on expanded testing for exposure.
Exposure to a mixture of per-and polyfluoroalkyl substances modulates pulmonary expression of ACE2 and circulating hormones and cytokines
18 Oct 2022 | Toxicol Appl Pharmacol
The effects of PFAS exposure in mice on gene expression and hormones were studied with respect to susceptibility to viral infections such as COVID-19.
