Influence of Perfluoroalkyl Substances on Occurrence of Coronavirus Disease 2019
Science
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.

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

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

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

Invited Perspective: The Promise of Fit-for-Purpose Systematic Evidence Maps for Supporting Regulatory Health Assessment
Science
17 May 2022 | EHP
A primary goal of systematic evidence maps (SEMs) in environmental health is to gather large amounts of data to support deeper scientific analyses and decision-making that protects public health and the environment. SEMs can be extremely useful for assessing large chemical classes, such as PFAS. However, a comparison of two different SEM approaches highlights that many available PFAS studies might not be considered in the U.S. EPA health assessments.

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

‘Forever chemicals’ found in nearly 60% of children’s ‘waterproof’ or ‘stain-resistant’ textiles
News
10 May 2022 | The Hill
Nearly 60% of children’s textiles labeled “waterproof”, “stain-resistant”, or “environmentally friendly” that were tested as part of a new study contained toxic PFAS substances known as “forever chemicals” due to their persistence in the environment.
