Per-and Polyfluoroalkyl Substances in Toilet Paper and the Impact on Wastewater Systems

1 Mar 2023 | ACS

Six PFAS were detected in toilet paper samples, and the most prevalent one, 6:2 diPAP, was estimated to contribute between 4% – 89% of 6:2 diPAP concentrations in sludge.

Acute Exposure of Zebrafish to the Next-Generation Perfluoroalkyl Substance, Perfluoroethylcyclohexanesulfonate, Shows Similar Effects as Legacy Substances

28 Feb 2023 | Environ Sci Technol

Exposure to the newer PFAS F-53B and OBS resulted in lower rates of activity as well as induced physiological changes within a human model species.

Association between polyfluoroalkyl substances exposure and sex steroids in adolescents: The mediating role of serum albumin

27 Feb 2023 | Ecotoxicol Environ Saf

Mixed exposure to PFAS was associated with endocrine disruption in developing adolescents, especially in girls, and serum albumin was found to play a possible mediating role in this association.

Bioaccumulation of Per- and Polyfluoroalkyl Substances (PFAS) in Ferns: Effect of PFAS Molecular Structure and Plant Root Characteristics

27 Feb 2023 | Environ Sci Technol

Exposure experiments found that long-chain PFAS collected in fern roots while short-chain PFAS collected in the fronds, demonstrating the feasibility of using ferns as bioindicators of PFAS pollution and the possibility of using ferns for restoration of PFAS-contaminated sites.

Review of Interim USEPA Health Advisories for PFOA and PFOS and Other Relevant Information

23 Feb 2023

The New Jersey Department of Environmental Protection Commissioner requested that the New Jersey Drinking Water Quality Institute review the scientific basis of the US EPA interim drinking water Health Advisories for PFOA and PFOS.

Toxicology assessment for six per- and polyfluoroalkyl (PFAS)-free aqueous film forming foam (AFFF) products

23 Feb 2023 | Integr Environ Assess Manag

PFAS-free AFFF products appear to have a lower likelihood of environmental persistence and bioaccumulation and have lower oral human health toxicity than PFAS-containing AFFF.

Metabolic Signatures of Youth Exposure to Mixtures of Per- and Polyfluoroalkyl Substances: A Multi-Cohort Study

22 Feb 2023 | EHP

Exposure to PFAS was associated with alterations in amino acid metabolism and lipid metabolism in young adults.

Per-and polyfluoroalkyl substances and volatile methyl siloxanes in global air: Spatial and temporal trends

22 Feb 2023 | Env. Poll.

Long-chain PFAS were detected globally in the environment, with PFOS levels still increasing at several sites despite its listing as a persistent organic pollutant to the Stockholm Convention since 2009.

Early-life exposure to per- and polyfluoroalkyl substances and infant gut microbial composition

22 Feb 2023 | Environ Epidemiol

PFAS may increase infant gut microbiome diversity and alter the relative abundance of biologically relevant bacteria.
