Extraction and Matrix Cleanup Method for Analyzing Novel Per- and Polyfluoroalkyl Ether Acids and Other Per- and Polyfluoroalkyl Substances in Fruits and Vegetables

24 May 2022 | J. Agric. Food Chem.

An extraction and cleanup method was developed to quantify 45 PFAS, including 13 PFEAs, 3 perfluoroalkane sulfonamides, and 6 fluorotelomer carboxylic acids in 10 types of fruits and vegetables.

Dermal uptake: An important pathway of human exposure to perfluoroalkyl substances?

24 May 2022 | Environ Pollut

The available literature on human dermal absorption of PFAS is critically reviewed and compared to other halogenated contaminants like brominated flame retardants, and the authors highlight the need for dermal permeation and uptake studies for a wide range of PFAS and their precursors.

PFAS use in electronic products and exposure risks during handling and processing of e-waste: A review

24 May 2022 | J Environ Manage

The wide use of PFAS in electronics presents a likely exposure source to workers at electronic-waste disposal sites given that PFAS have been detected in environmental and human samples near waste processing sites.

Influence of Perfluoroalkyl Substances on Occurrence of Coronavirus Disease 2019

24 May 2022 | Int J Environ Res Public Health

PFAS exposures occurring early in life may cause deleterious health effects later in life, including decreased antibody response and reduced disease resistance. Highest levels of both PFAS exposure and COVID-19 were found in the oldest populations.

Systematic Evidence Map for Over One Hundred and Fifty Per- and Polyfluoroalkyl Substances (PFAS)

24 May 2022 | Environ Health Perspect

More than 40,000 studies were identified to compile epidemiological evidence for 150 PFAS, and it was found that many PFAS lack sufficient data to determine health impacts.

Emerging and Legacy Per- and Polyfluoroalkyl Substances in an Elderly Population in Jinan, China: The Exposure Level, Short-Term Variation, and Intake Assessment

24 May 2022 | Environ Sci Technol

Dietary ingestion, especially fish, was likely an important exposure pathway for PFAS among elderly adults in one city.

Sorption of Per-and Polyfluoroalkyl Substances (PFAS) using Polyethylene (PE) microplastics as adsorbent: Grand Canonical Monte Carlo and Molecular Dynamics (GCMC-MD) studies

17 May 2022 | Int. J. Environ. Anal. Chem.

Several PFAS were found to easily sorb on to polyethylene microplastics, especially as pollutant concentration increased.

Pilot-Scale Continuous Foam Fractionation for the Removal of Per-and Polyfluoroalkyl Substances (PFAS) from Landfill Leachate

17 May 2022 | ACS ES&T Water

Foam fractionation was found to remove PFAS from landfill leachate, with higher removal efficiencies for long-chain PFAS compared to short-chain PFAS.

Ultra-Short-Chain PFASs in the Sources of German Drinking Water: Prevalent, Overlooked, Difficult to Remove, and Unregulated

17 May 2022 | ES&T

Ultra-short-chain PFAS represent a major challenge in drinking water due to their high concentrations, greater mobility, and lack of remediation options, which shows that regulation through preventive measures is required to manage them.

Fluorine Mass Balance Analysis and Per-and Polyfluoroalkyl Substances in the Atmosphere

17 May 2022 | J. Hazard. Mater.

Ultra-short-chain PFAS were identified as the predominant components in outdoor air and organofluorine compounds were found to concentrate indoors in fine particles. A fluorine mass balance analysis revealed that up to 99% of PFAS in the atmosphere are unidentified.

Environmental Exposure to 6:2 Polyfluoroalkyl Phosphate Diester and Impaired Testicular Function in Men

17 May 2022 | Environ Sci Technol

Exposure to 6:2 diPAP may impair androgen synthesis and Leydig cell function in adult men, reducing the ability to regulate hormones.

Official health communications are failing PFAS-contaminated communities

10 May 2022 | Environmental Health

Immediate action should be undertaken to review and improve official health communications intended to inform the public and health providers about the risks of PFAS exposure and guide community and medical decisions.

Interaction of Per-and Polyfluoroalkyl Substances and Allostatic Load among Adults in Various Occupations

10 May 2022 | Diseases

Increased chronic physiological stress was positively associated with serum concentrations of certain PFAS, as well as with different occupation groups such as Public Administration and Arts, Entertainment, and Recreation.

Ultra-Short-Chain PFASs in the Sources of German Drinking Water: Prevalent, Overlooked, Difficult to Remove, and Unregulated

10 May 2022 | ES&T

“PFAS total” parameters like the adsorbable organic fluorine and total oxidizable precursor assay were found to provide only an incomplete picture of PFAS contamination in these water samples by not capturing these highly prevalent ultra-short-chain PFASs.
