Flushing Home Plumbing Pipes Contaminated with Aqueous Film-Forming Foam Containing Per- and Polyfluoroalkyl Substances
24 Jun 2023 | J Environ Eng
Drinking water systems can be contaminated with AFFF through backflushing, and while flushing was found to reduce PFAS water concentrations 99.5-99.99%, PFAS were found to increase after stagnation likely due to PFAS adhered on water pipes.
Toward systematic understanding of adsorptive removal of legacy and emerging per-and polyfluoroalkyl substances (PFASs) by various activated carbons (ACs)
24 Jun 2023 | Environ Res
Particle size and surface properties of activated carbon affect their efficiency for PFAS removal, with increased efficiency when the activated carbon was chemically treated.
First Investigation of the Physiological Distribution of Legacy and Emerging Perfluoroalkyl Substances in Raw Bovine Milk According to the Component Fraction
22 Jun 2023 | Foods
In milk from 23 cows with no known PFAS exposure, PFOS was found in higher concentrations in cream compared to raw and skim milk, and PFBA was the most common PFAS detected.
Domestic Dogs and Horses as Sentinels of Per- and Polyfluoroalkyl Substance Exposure and Associated Health Biomarkers in Gray's Creek North Carolina
20 Jun 2023 | Environ Sci Technol
Many PFAS were detected in dogs and horses in areas with documented PFAS contamination, and as in humans, liver and kidney health in domestic animals may be sensitive to long-term PFAS exposures.
Levels of PFAS concentrations in the placenta and pregnancy complications
20 Jun 2023 | Ecotoxicol Environ Saf
PFOA concentrations in the placenta appeared to be associated with adverse perinatal outcomes, consistent with findings for PFAS concentrations in blood.
[Report] Per- and Polyfluoroalkyl Substances in New Firefighter Turnout Gear Textiles
19 Jun 2023 | NIST
Total PFAS concentrations varied widely among each textile type, suggesting that the amount of PFAS present in new turnout gear may depend on the specific textiles used in gear manufacturing.
Plasma concentrations of per- and polyfluoroalkyl substances in pregnancy and breastfeeding duration in Project Viva
19 Jun 2023 | Sci. Tot. Env.
Higher plasma PFAS in pregnancy was associated with shorter breastfeeding duration.
Legacy and emerging per-and polyfluoroalkyl substances in polar regions
17 Jun 2023 | Curr. Opin. Green Sustain. Chem.
Glacier melting and sea ice retreat can act as secondary sources of PFAS in polar regions.
Estimation of Serum PFOA Concentrations from Drinking and Non–Drinking Water Exposures
16 Jun 2023 | EHP
PFAS-contaminated sites should be remediated and drinking water containing PFAS should be treated; however, to achieve meaningful reductions in serum PFAS, a comprehensive national approach must be undertaken to reduce PFAS exposures from all sources, including banning PFAS in food, consumer products, and other nonessential uses.
Close association of PFASs exposure with hepatic fibrosis than steatosis: evidences from NHANES 2017–2018
15 Jun 2023 | Ann Med
PFOS has been identified as a potential primary contributor to the development of PFAS-related hepatic fibrosis.
Estimated exposure to perfluoroalkyl substances during infancy and serum-adipokine concentrations in later childhood
14 Jun 2023 | Pediatr Res
Early childhood exposure to PFAS may affect later metabolic health by altering levels of hormones that affect growth and risk of developing obesity.
Occurrence of Per- and Polyfluoroalkyl Substance Contamination of Food Sources and Aquaculture Organisms Used in Aquatic Laboratory Experiments
13 Jun 2023 | Environ Toxicol Chem
The most frequently detected PFAS in fish feed and aquaculture fathead minnows were PFCAs and PFOS, with freeze‐dried bloodworms and frozen brine shrimp being the most polluted.
