Fig. 2: PFAAs at surface versus the deep chlorophyll maximum (DCM) depth.

Correlations between concentrations (pg L−1) at 5 m and DCM. Orange dots account for PFSAs (PFBS, PFHxS, PFOS, PFECHS, PFDS, and PFDoDS) and blue dots for PFCAs (PFPeA, PFHpA, PFOA, PFNA, PFDA, PFUnDA, PFDoDA, PFTrDA, PFTeDA, PFHxDA, and PFODA).
