► Firstly evidence of PFASs in the abiotic multi-matrices in Antarctic was provided. ► PFBA and PFOS in Antarctica are affected by the degradation of their precursors. ► PFOA contamination in the Antarctic research station area mainly originate from point sources. ► Results are useful for global transport models of PFASs, especially for PFBA and PFOS.
