Biota-Sediment Accumulation Factors for Per- and Polyfluoroalkyl Substances

Environmental Toxicology and Chemistry, 2022
Abstract Per- and polyfluoroalkyl substances (PFAS) are widely used in commercial products such textiles, firefighting foams, and surface coatings across the globe and some PFAS are known to be bioaccumulative in aquatic species. The ultimate sink for numerous anthropogenic chemicals is the sediments in lakes, rivers, and oceans.

Assessing Per- and Polyfluoroalkyl Substances in Globally Sourced Food Packaging

Chemosphere, 2023
The purpose of this study was to investigate the presence and levels of per- and polyfluoroalkyl substances (PFAS) in food packaging originating from different geographic locations. Food packaging samples were extracted and analyzed by targeted analysis with liquid chromatography-mass spectrometry (LC-MS/MS) before and after a total oxidizable ...

Uptake and accumulation of per- and polyfluoroalkyl substances in plants

Chemosphere, 2020
Per- and polyfluoroalkyl substances (PFASs) are a class of persistent organic contaminants that are ubiquitous in the environment and have been found to be accumulated in agricultural products. Consumption of PFAS-contaminated agricultural products represents a feasible pathway for the trophic transfer of these toxic chemicals along food chains/webs ...
