Per- and polyfluoroalkyl substances (PFAS) accumulation in fish occupying different trophic positions from East Canyon Creek, a seasonally effluent-dominated river, Utah, USA.

Fish and seafood are considered a major source of human dietary exposure to per- and polyfluoroalkyl substances (PFAS). In this study, we examined levels of 35 PFAS in fish samples of brown trout and mottled sculpin, which occupy different trophic positions, collected in 2014 from East Canyon Creek in Utah, USA. We observed 20 PFAS with ∑PFAS ranging from 0.46-63.9 ng/g and from
