A Critical Review and Meta-Analysis of Impacts of Per- and Polyfluorinated Substances on the Brain and Behavior

2 May 2022 | Front Toxicol

This review summarizes concerns about PFAS accumulation in the brain, neurotoxicity, and PFAS exposure during development, and notes the lack of studies on realistic chronic PFAS exposure of low dose mixtures.

Critical Review of Thermal Decomposition of Per- and Polyfluoroalkyl Substances: Mechanisms and Implications for Thermal Treatment Processes

2 May 2022 | Environ Sci Technol

This review discusses thermal treatment as a way to destroy PFAS, and highlights that a major weakness of existing studies is that they do not mimic the full-scale thermal treatment systems that are actually used for PFAS incineration.

The California GeoTracker Database: A Unique Public Resource for Understanding Contaminated Sites

26 Apr 2022 | Ground Water Monit Remediat

This paper describes the origins of California’s GeoTracker website and how it evolved to account for changes in regulatory priorities and illustrates how long-term commitment to the collection of environmental data can support the general public and regulatory and research communities.

Levels and Temporal Trends of Trifluoroacetate (TFA) in Archived Plants: Evidence for Increasing Emissions of Gaseous TFA Precursors over the Last Decades

26 Apr 2022 | ES&T

TFA concentrations in plants were found to increase over several decades, likely due to increasing anthropogenic emissions of TFA precursors. The very high persistence and mobility of TFA in the environment mean that TFA and its precursors should be considered for regulation.

Bioaccumulation and Translocation of 6: 2 Fluorotelomer Sulfonate, GenX, and Perfluoroalkyl Acids by Urban Spontaneous Plants

26 Apr 2022 | ACS ES&T Engineering

Several types of PFAS were found to accumulate in urban weeds, with higher PFAS concentrations in plants with smaller leaves and finer roots.

Characterizing firefighter's exposure to over 130 SVOCs using silicone wristbands: A pilot study comparing on-duty and off-duty exposures

26 Apr 2022 | Sci Total Environ

Firefighter exposure to PFOS was significantly higher while responding to fires compared to while off-duty, and high exposure to phthalates and flame retardants was also observed.

American oysters as bioindicators of emerging organic contaminants in Florida, United States

26 Apr 2022 | Sci Total Environ

All studied PFAS and phthalate esters were present in at least one oyster across three sites throughout Florida, and a human health risk assessment indicated low risk.

Association between serum per-and polyfluoroalkyl substances concentrations and common cold among children and adolescents in the United States

19 Apr 2022 | Environ. Int.

In children, blood concentrations of PFAS mixtures and individual PFAS were associated with higher odds of common cold, especially in males.

Widespread Occurrence of Non-Extractable Fluorine in Artificial Turfs from Stockholm, Sweden

19 Apr 2022 | Analytical Chemistry

Results suggest the use of polymeric organofluorine in artificial turf, such that the production, end-of-life, and microplastic concerns are greater than the risk to users.

Per-and polyfluoroalkyl substances and incident diabetes in midlife women: the Study of Women’s Health Across the Nation (SWAN)

19 Apr 2022 | Diabetologia

This study suggests that PFAS may increase diabetes risk in midlife women.

Fate of Per-and Polyfluoroalkyl Substances from Durable Water-Repellent Clothing during Use

19 Apr 2022 | ES&T

Aging and washing of fabrics with durable water-repellant coatings made with PFAS release PFAS to the environment, while tumble drying does not affect the PFAS concentrations in textiles.

Environmental exposure to legacy poly/perfluoroalkyl substances, emerging alternatives and isomers and semen quality in men: A mixture analysis

19 Apr 2022 | Sci Total Environ

6:2 Cl-PFESA, PFBS, and PFHxS exposure was associated with reduced semen quality, but there were no consistent associations between PFAS mixtures and semen quality.

[Resource] What We Know: Per- and polyfluoroalkyl substances (PFAS) AAAS EPI Center

12 Apr 2022

There is not yet enough research to suggest safe exposure levels for each PFAS. An increasing number of communities across the United States are detecting these chemicals and working to address PFAS contamination.

PFAS on Atmospheric Aerosol Particles: A Review

12 Apr 2022 | Environ Sci Process Impacts

Long-term monitoring of PFAS on the particulate matter should be expanded to include under-sampled regions of the world and further non-targeted analysis is needed to identify novel PFAS structures as PFAS manufacturing and regulations continue to evolve.

Perfluoroalkyl substance mixtures and cardio-metabolic outcomes in highly exposed male workers in the Veneto Region: A mixture-based approach

12 Apr 2022 | Environ Res

A clear association between serum PFAS levels and markers of cardiovascular risk was found, which supports the importance of clinical surveillance of cardiovascular risk factors in populations with high exposure to PFAS, especially in the occupational setting.
