Systematic review and meta-analysis of birthweight and PFNA exposures
24 Jan 2023 | Environ Res
Data analysis techniques allowing for more studies to be included in this review resulted in a stronger connection between birthweight deficits and PFNA exposure compared to previous PFAS meta-analyses.
Leaching of Perfluoroalkyl Acids during Unsaturated Zone Flushing at a Field Site Impacted with Aqueous Film Forming Foam
23 Jan 2023 | Environ Sci Technol
Remedial approaches that remove only a modest fraction of the PFAA mass in soil may be protective of underlying groundwater, particularly for some perfluorinated sulfonates.
Bioaccessibility of per- and polyfluoroalkyl substances in food and dust: Implication for more accurate risk assessment
20 Jan 2023 | Sci Total Environ
The bioaccessibility of PFAS was higher in simulated animal foods than in simulated vegetable foods, and the bioaccessibility of most very long-chain PFAS was higher in food than in dust.
Optimizing Chemicals Management in the United States and Canada through the Essential-Use Approach
19 Jan 2023 | Environ Sci Technol
If optimized and expanded into regulatory systems in the United States and Canada, other policymaking bodies, and businesses, the essential-use approach can improve chemicals management and shift the market toward safer chemistries that benefit human and ecological health.
The role of PFAS in unsettling ocean carbon sequestration
18 Jan 2023 | Environ Monit Assess
The harmful effects of PFAS on marine ecosystems may weaken the ocean’s ability to capture and hold global warming carbon emissions.
Evaluation of per- and polyfluoroalkyl substances (PFAS) in leachate, gas condensate, stormwater and groundwater at landfills
17 Jan 2023 | Chemosphere
To prioritize and improve PFAS remediation from discarded consumer products, relationships were found between PFAS and landfill characteristics, including aqueous samples like leachate and stormwater.
Prenatal exposure to per- and polyfluoroalkyl substances and childhood autism-related outcomes
12 Jan 2023 | Epidemiology
Mothers’ prenatal blood concentrations of PFNA may be associated with modest increases in their child’s autism-related traits.
PFAS Biotransformation Pathways: A Species Comparison Study
12 Jan 2023 | Toxics
A metabolic pathway map was made to aid researchers in determining possible PFAS breakdown products in fish when no metabolic data is present.
A Proposed approach to defining per- and polyfluoroalkyl substances (PFAS) based on molecular structure and formula
11 Jan 2023 | Integr Environ Assess Manag
A definition of PFAS was proposed based on four substructures and any structures where the molecular formula is at least 30% fluorine by atom count.
Occurrence and implications of per and polyfluoroalkyl substances in animal feeds used in laboratory toxicity testing
10 Jan 2023 | Sci Total Environ
PFAS contamination in animal feed was found to be pervasive, which is significant because unintended PFAS exposure in control animals from feed can significantly bias toxicity testing.
In utero exposure to perfluoroalkyl substances and early childhood BMI trajectories: A mediation analysis with neonatal metabolic profiles
9 Jan 2023 | Sci Total Environ
Prenatal PFAS exposure was associated with persistently increased BMI in childhood.
Rapid Determination of Selected PFAS in Textiles Entering the Waste Stream
6 Jan 2023 | Toxics
A rapid extraction and clean-up method was developed for the determination of 21 PFAS in various polymers used in soft furnishings and upholstery.
Associations between per and polyfluoroalkyl ether sulfonic acids and vitamin D biomarker levels in Chinese newborns
5 Jan 2023 | Sci Total Environ
Exposure to legacy PFAS, including PFTrDA, PFHxS, and PFOS, might disturb vitamin D status in newborns.
Per- and polyfluoroalkyl substances (PFAS) presence in food: Comparison among fresh, frozen and ready-to-eat vegetables
5 Jan 2023 | Food Chem
Italian ready-to-eat vegetables contained higher PFAS levels than fresh/frozen products, and organic vegetables had lower PFAS contents than their traditional counterparts.
Emerging and legacy contaminants in common minke whale from the Barents sea
4 Jan 2023 | Environ Pollut
PFAS levels were higher in fetuses than male or female adult whales, and PFOS levels were higher than those detected from the same population eight years previously.
