- •
Simultaneous extraction of PFSAs, PFCAs, diPAPs, PFPiAs and PFPAs from sediment.
- •
PFAS contribution in Lake Ontario was dominated by PFOS.
- •
Remote lakes contained sediment with higher proportions of PFCAs and diPAPs.
- •
PFAS concentrations increased with time but proportion of PFOS to ƩPFAS decreased.
