Impact of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) on secondary sludge microorganisms: removal, potential toxicity, and their implications on existing wastewater treatment regulations in Canada

There is limited data on perfluorinated PFAS, with PFOS and PFOA dominating the research field. Laboratory studies with these two compounds demonstrate potential biodegradation and bioadsorption, but also show negative impacts on the performance of AS and AGS after long-term exposure.
