Estimation of the Half-Lives of Recently Detected Per- and Polyfluorinated Alkyl Ethers in an Exposed Community

ENVIRONMENTAL SCIENCE & TECHNOLOGY, 57(41), 15348–15355.

By: D. Wallis n, N. Kotlarz n , D. Knappe n , D. Collier *, C. Lea *, D. Reif n , J. McCord *, M. Strynar *, J. DeWitt*, J. Hoppin n 

author keywords: exposure; PFAS; water; humans; environment; toxicokinetic modeling
TL;DR: These fluoroethers had biological half-Lives longer than published half-lives for PFHxA and PFHpA but shorter than those for PFOA andPFOS (800-1200 days). (via Semantic Scholar)

Factors associated with per- and polyfluoroalkyl substances (PFAS) serum concentrations in residents of New Hanover County, North Carolina: The GenX exposure study

ENVIRONMENTAL RESEARCH, 237.

By: M. Cuffney n , A. Wilkie n, N. Kotlarz n , D. Knappe n , C. Lea  n, D. Collier  n, J. Dewitt n, J. Hoppin n 

author keywords: Per-and polyfluoroalkyl substances (PFAS); Fluoroethers; Contaminated drinking water; Environmental exposure predictors
TL;DR: It is shown that drinking water is a primary source for serum PFAS concentrations among New Hanover County residents and years of residence in the lower Cape Fear Region as a surrogate for water consumption were important for both the association and predictive investigations.

Legacy and emerging per- and polyfluoroalkyl substances suppress the neutrophil respiratory burst

JOURNAL OF IMMUNOTOXICOLOGY, 20(1).

By: D. Phelps* , A. Palekar, H. Conley*, G. Ferrero, J. Driggers*, K. Linder*, S. Kullman n , D. Reif n  ...

author keywords: Innate immunity; neutrophils; per- and polyfluoroalkyl substances (PFAS); reactive oxygen species; zebrafish
MeSH headings : Animals; Humans; Zebrafish; Neutrophils; Reactive Oxygen Species; Respiratory Burst; Fluorocarbons / toxicity; Alkanesulfonic Acids / toxicity; Environmental Pollutants
TL;DR: This report is the first to demonstrate that these PFASs suppress neutrophil function and support the utility of employing zebrafish larvae and a human cell line as screening tools to identify chemicals that may suppress human immune function. (via Semantic Scholar)
