“…The simulation is continued with zero inputs between 2010 and 2038 to capture the phaseout in PFOS production. We divide annual inputs equally over each 3 h time step in the model simulation because available monitoring data do not show significant seasonal differences (supporting information Table S1) [Boulanger et al, 2004;Schultz et al, 2006;Loganathan et al, 2007;Plumlee et al, 2008;Erickson et al, 2009;Furl et al, 2011;Furdui et al, 2008;D'eon et al, 2009;Guerra et al, 2014]. We developed a time-dependent inventory of PFOS inputs from wastewater treatment plants and rivers to the North Atlantic between 1958 and 2010.…”

Perfluorooctane sulfonate (PFOS) is an aliphatic fluorinated compound with eight carbon atoms that is extremely persistent in the environment and can adversely affect human and ecological health. The stability, low reactivity, and high water solubility of PFOS combined with the North American phaseout in production around the year 2000 make it a potentially useful new tracer for ocean circulation. Here we characterize processes affecting the lifetime and accumulation of PFOS in the North Atlantic Ocean and transport to sensitive Arctic regions by developing a 3‐D simulation within the MITgcm. The model captures variability in measurements across biogeographical provinces (R2 = 0.90, p = 0.01). In 2015, the North Atlantic PFOS reservoir was equivalent to 60% of cumulative inputs from the North American and European continents (1400 Mg). Cumulative inputs to the Arctic accounted for 30% of continental discharges, while the remaining 10% was transported to the tropical Atlantic and other regions. PFOS concentrations declined rapidly after 2002 in the surface mixed layer (half‐life: 1–2 years) but are still increasing below 1000 m depth. During peak production years (1980–2000), plumes of PFOS‐enriched seawater were transported to the sub‐Arctic in energetic surface ocean currents. However, Atlantic Meridional Overturning Circulation (AMOC) and deep ocean transport returned a substantial fraction of this northward transport (20%, 530 Mg) to southern latitudes and reduced cumulative inputs to the Arctic (730 Mg) by 70%. Weakened AMOC due to climate change is thus likely to increase the magnitude of persistent bioaccumulative pollutants entering the Arctic Ocean.

“…PFOS was predominant at sites AHS-13, AHS-14, AHS-15, AHS-16 and AHS-18 from the downstream reach of the Huaihe River. PFASs in aquatic systems can arise from point sources, such as sewage outfalls, and non-point sources, such as dry and wet deposition or runoff inputs (Furl et al, 2011). Among the PFCAs analyzed, PFBA was predominant, with concentration ranging from n.d. to 0.31 ng/g dw.…”

“…Contamination of aquatic ecosystems with PFASs results from a combination of non-point and point sources, being point sources responsible for much of the pollution (Furl et al, 2011;Zushi and Masunaga, 2011). Especially important are the sewage treatment plant (STPs) discharges, since these plants appear to be ineffective eliminating PFASs, and consequently can be a significant source of these compounds to the aquatic environment, potentially reaching treated water for human consumption.…”
