The field-based distribution and bioaccumulation factor (BAF) for per- and polyfluoroalkyl substances (PFASs) were determined in residential Black Swans () from an urban lake (Melbourne, Australia). The concentrations of 46 aliphatic and cyclic PFASs were determined by HPLC-MS/MS in serum and excrement from swans, and water, sediment, aquatic macrophytes, soil, and grass samples in and around the lake. Elevated concentrations of ∑PFASs were detected in serum (120 ng mL) and excrement (110 ng g dw) were strongly related indicating a potential noninvasive sampling methodology.

Samples were analysed for 44 PFAS using isotope dilution and alkaline extraction coupled with quantification with LC-MS/MS. The ΣPFAS mean concentration was 260 ng/g dry weight (dw) and ranged between 4.

The new Australian PFAS National Environmental Management Plan recommends 0.23 ng L of PFOS as the guideline value for 99% species protection for aquatic systems.
