An Ecosystem-Scale Model of PFAS Dynamics in Stream-to-Riparian Food Webs
PFAS concentrations (5.4-51 ppb wet weight), body burdens (0.44-5.2 ng per individual), and bioamplification factors (0.15-4.9) differed considerably among five common aquatic insect taxa. This study presents a robust modeling framework for PFAS trophodynamics and offers insights into the biological controls that contribute to the context dependency of PFAS at the interfaces of aquatic and terrestrial food webs.
