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.

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.

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.
