Half-lives of several polyfluoroalkyl substances (PFAS) in cattle serum and tissues

Cattle that were at steady-state serum polyfluoroalkyl substances (PFAS) concentrations due to several years of exposure to water contaminated by residues of Aqueous Film-Forming (AFFF) firefighting foam had perfluorooctane sulphonate (PFOS) isomers, perfluoroheptane sulphonate (PFHpS), perfluorohexane sulphonate (PFHxS), perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) in serum. Elimination serum half-lives were determined in five heifers…

Removal of per- and poly-fluoroalkyl substances (PFASs) by wetlands: Prospects on plants, microbes and the interplay

This review focuses on how plants, microbe, substrate can influence PFASs removal in wetlands under natural and controlled conditions. August 25, 2021 | Science of The Total Environment

Occurrence and toxicity of perfluoroalkyl acids along the estuarine and coastal regions under varied environmental factors

This study compiled the data on the levels of PFAAs in environmental samples, mainly in estuarine and coastal zones. A worldwide map was generated to show the distribution of PFAAs along with variety of environmental factors. January 9, 2021 | Science of the Total Environment


Understanding PFAAs exposure in a generalist seabird species breeding in the vicinity of a fluorochemical plant: influence of maternal transfer and diet

Study examined PFOA and PFOS exposure in chicks of a generalist seabird species, the lesser black-backed gull breeding 49 km away of a PFAS hotspot (a fluorochemical plant in Antwerp, Belgium). December 18, 2020 | Environmental Pollution
