The concerns of PFAS toxicity led to voluntarily phasing out of perfl uorooctanesulfonic acid (PFOS) by its manufacturer. Shorter chain PFAS, such as perfl uorobutanesulfonic acid (PFBS), are suggested to be less toxic alternatives with decreased environmental persistence. In t...

We used a large, publicly available dataset of perfluoro鈥恘鈥恛ctane sulfonic acid (PFOS) concentrations in water and fish tissue to (1) evaluate overall patterns and drivers of water and fish tissue PFOS concentrations and derived BAFs, and (2) quantify how biological, environmental, and ...
Perfluorobutyl (C4) substituted linear C4-C4 ether linked tri-sodium sulfonate derivatives are designed, synthesized and characterized as alternative substances to perfluoroctanesulfonic acid (PFOS, 1), a well known surfactant used in various industrial and consumer products. The tri-sodium sulfonate ...
