Biotransformation of fluorotelomer (FT) compounds, such as 8:2 FT alcohol (FTOH) is now recognized to be a source of perfluorooctanoic acid (PFOA) as well as other perfluoroalkyl acids. In this study, microbially mediated hydrolysis of FT industrial intermediates 8:2 FT acrylate (8:2 FTAC) and 8:2 FT methacrylate (8:2 FTMAC) was evaluated in aerobic soils for up to 105d. At designated times, triplicate...
The experimental approaches used in assessing the biodegradability of fluorotelomer-based surfactants and polymers have been under increasing scrutiny. These substances consist of an aliphatic or aromatic backbone linked to perfluoroethyl moieties by ester, ether or urethane linkages. These linkages when broken yield fluorotelomer alcohols (FTOHs), which are known to biotransform to a suite of polyfluorinated...
