The unheeded inherent connections and overlap between microplastics and poly-and perfluoroalkyl substances: A comprehensive review

22 Mar 2023 | Sci. Total Environ.

The combined toxicity of microplastics and PFAS usually results in greater health harm, with some compounds being recognized as both microplastics and PFAS.

Per-and polyfluoroalkyl substances: using comparative medicine to understand exposure and adverse health outcomes in people and their pets

22 Mar 2023 | AVMA

Research suggests that soon the tools to effectively use dogs and cats as predictors of human exposure to PFAS will be available, ultimately protecting the lives of children and animals who live in the same household.

Assessing the environmental occurrence of the anthropogenic contaminant trifluoroacetic acid (TFA)

17 Mar 2023 | Curr. Opin. Green Sustain. Chem.

This review summarizes current knowledge on trifluoroacetic acid, most notably its substantial increases in environmental samples over the past few decades.

Birth Outcomes in Relation to Prenatal Exposure to Per- and Polyfluoroalkyl Substances and Stress in the Environmental Influences on Child Health Outcomes (ECHO) Program

15 Mar 2023 | Environ Health Perspect

High levels of exposure to PFOA, PFOS, PFNA, and PFHxS were associated with lower birthweights in a large multi-cohort study.

Perfluorooctanoic Acid (PFOA) Incorporated into Iron Particles Promoted the Formation of Disinfection Byproducts under Drinking Water Conditions

14 Mar 2023 | Environ Sci Technol

PFOA may interact with iron pipes to increase the formation of potentially hazardous chemicals in drinking water.

Evaluating Neutral PFAS for Potential Dermal Absorption from the Gas Phase

14 Mar 2023 | Environ Sci Technol

11 occupationally-relevant PFAS were estimated to be absorbed into the body more efficiently through dermal absorption than inhalation, suggesting that PFAS dermal absorption from the gas phase may need to be included in PFAS exposure guidelines.

Current per- and polyfluoroalkyl substance (PFAS) research points to a growing threat in animals

13 Mar 2023 | J Am Vet Med Assoc

Given the widespread PFAS exposure in livestock as well as pets, this review summarizes the current literature on PFAS in animals and discusses the implications for veterinary patients.

Ecotoxicity Evaluation of Fire-Extinguishing Water from Large-Scale Battery and Battery Electric Vehicle Fire Tests

13 Mar 2023 | Environ Sci Technol

The extinguishing water from vehicle fire tests found to be very toxic due to metals, PAHs, PFAS, and more, with most PFAS originating from the electric vehicle battery compared to the vehicle itself or conventional fuel.

Positive outcomes from U.S. lead regulations, continued challenges, and lessons learned for regulating emerging contaminants

10 Mar 2023 | Environ Sci Pollut Res Int

More proactive planning, communication, and research of common and persistent emerging contaminants of concern (i.e., PFAS) should be prioritized so that the same mistakes are not repeated.

Sex-Specific Bioaccumulation, Maternal Transfer, and Tissue Distribution of Legacy and Emerging Per- and Polyfluoroalkyl Substances in Snakes () and the Impact of Pregnancy.

7 Mar 2023 | Environ Sci Technol

Significant differences in PFAS concentrations and chemical compositions were found in pregnant females than in males and non-pregnant females, likely due to physiological changes during pregnancy.

Directly Fluorinated Containers as a Source of Perfluoroalkyl Carboxylic Acid

6 Mar 2023 | Environ. Sci. Technol. Lett.

Leaching experiments demonstrated that PFAS from fluorinated plastic containers can migrate into food, suggesting that regulatory action is warranted.
