Description
The concentrations of Per- and Polyfluoroalkyl Substances (PFASs) in the environment or in human serum has markedly decreased since the PFOA Stewardship Program was established and was registered with the Stockholm Convention. An increase in PFHxA has been reported with a decrease in PFOA. As precursors, N-MeFOSA and N-EtFOSA were detected in seawater using Orbitrap-MS and as a result, 5:2 Ketone, 5:3 FTCA, 6:2 FTOH, 6:2 diPAP, and 6:2 FTS were detected. There have also been recent reports of GenX contamination and cases of detection.<br> On the one hand, there have been almost no cases of hexabromocyclododecane (HBCD) surveyed at the landfill, but the concentration range still measured <0.0025 to 9ng・L−1. At the sewage treatment plant, the concentration range for the inflow water was at <0.4 to 400ng・L−1 with effluent numbers at 0.14 to 18ng・L−1. It is notable that the concentration level decreased with treatment. In the future, by analyzing various water samples such as from landfill leachate, etc., we intend to address and solve problems with the aim of creating a manual that provides analysis and survey methods.
