Fluorinated Compounds in U.S. Fast Food Packaging.
TLDR
The prevalence of fluorinated chemicals in fast food packaging demonstrates their potentially significant contribution to dietary PFAS exposure and environmental contamination during production and disposal. Expand
A critical review of the postulated role of the non-essential amino acid, β-N-methylamino-L-alanine, in neurodegenerative disease in humans
TLDR
The hypothesis that BMAA is the critical factor in the genesis of these neurodegenerative diseases received considerable attention in the medical, scientific, and public arenas and is not supported by existing data. Expand
Orthogonal zirconium diol/C18 liquid chromatography-tandem mass spectrometry analysis of poly and perfluoroalkyl substances in landfill leachate.
TLDR
The 3-perfluoropentyl propanoate (5:3 FTCA) was the most concentrated analyte in most samples and constitutes a previously unreported but significant component of landfill leachate. Expand
pH dependent octanol-water partitioning coefficients of microcystin congeners.
TLDR
The variation in pH dependent hydrophobicity suggests increased propensity for bioaccumulation and alternate environmental fates for differing microcystin forms, requiring further investigation. Expand
National Estimate of Per- and Polyfluoroalkyl Substance (PFAS) Release to U.S. Municipal Landfill Leachate.
TLDR
The concentrations of 70 PFASs in 95 samples of leachate were measured in a survey of U.S. landfills of varying climates and waste ages and six PFAS demonstrated significant variation with climate. Expand
Physical and Biological Release of Poly- and Perfluoroalkyl Substances (PFASs) from Municipal Solid Waste in Anaerobic Model Landfill Reactors.
TLDR
This study models how PFASs enter leachate using four laboratory-scale anaerobic bioreactors filled with municipal solid waste and operated over 273 days to evaluate influences attributable to biological activity. Expand
Release of Per- and Polyfluoroalkyl Substances (PFASs) from Carpet and Clothing in Model Anaerobic Landfill Reactors.
TLDR
Monitoring of anaerobic model landfill reactors filled with carpet or clothing demonstrated that carpet and clothing are likely sources of PFASs in landfill leachate. Expand
Cylindrospermopsin toxicity in mice following a 90-d oral exposure
TLDR
Toxicity was noted at all dose levels, and the 75 µg/kg group exhibited significant effects in liver and kidney/body weight ratios, reduced BUN, increased serum monocytes, and multiple signs of histopathology indicating that a no-observed-adverse-effect level could not be determined for any dose level. Expand
Waste type, incineration, and aeration are associated with per- and polyfluoroalkyl levels in landfill leachates.
TLDR
Results indicate that MSWA leachates had significantly lower PFAS levels relative to other leachate types, and the levels of targeted PFAS species in MSWLeachate for one of the facilities evaluated increased after on-site landfill treatment presumably due to the conversion of PFAS precursors in the untreated leachATE sample. Expand
The Comparative Toxicity of 10 Microcystin Congeners Administered Orally to Mice: Clinical Effects and Organ Toxicity
TLDR
A wide spectrum of hepatic effects and different potencies of these microcystin-LR congeners identified in algal blooms are illustrated, including a high percentage of moribundity and liver congestion associated with hepatic toxicity. Expand
