Bioaccumulation of perfluorooctane sulfonic acid (PFOS) and oxidative stress in snapping turtles in New York, USA

Perfluorooctane sulfonic acid (PFOS) is an anthropogenic chemical found in aqueous film-forming foams (AFFFs) and many consumer products. Despite its environmental ubiquity and persistence, little is known about the effects of PFOS on stress levels in wild animals. Here, we examined PFOS bioaccumulation and correlations between PFOS exposure and oxidative stress in snapping turtles (Chelydra serpentina) downstream of Griffiss Air Force Base in Rome, New York, a known source of AFFF contamination. Maximum concentrations of PFOS were extrapolated as 41.7 ppb and 498 ppb in water and turtle samples, respectively; in comparison, the proposed United States national advisory concentration of PFOS in drinking water is currently 0.00002 ppb. PFOS concentrations declined with distance downstream from the base and were lower in other local water bodies. Indices of oxidative stress were positively correlated with plasma PFOS concentrations in snapping turtles. These data illuminate the potential f..., On 6 October 2020, water samples were collected for PFAS analysis from six locations: one 5 km upstream of the contamination point in Sixmile Creek, four 0–1500 m downstream of the contamination point in Sixmile Creek, and one in the Erie Canal, 2,250 m downstream of the contamination point. Stream water samples (30 mL, collected in triple-rinsed Falcon centrifuge tubes) were stored at −20o °C until analysis.
Twenty-nine blood samples were collected from snapping turtles between June and September of 2021. Turtle sampling locations included three sites downstream of the contamination point in Sixmile Creek, one site at Stony Creek Pond adjacent to a Department of Defense Fuel Depot fuel storage facility, which was also known to have PFAS contamination, and three control sites (Delta Lake, South Otselic Fish Hatchery, and Camroden Pond) with no known PFAS contamination. Snapping turtles were captured in hoop nets, and Tomahawk traps baited with tuna. Traps were checked within 24 hours af..., , # Data from: Bioaccumulation of perfluorooctane sulfonic acid (PFOS) and oxidative stress in snapping turtles in New York, USA
