Ecotoxicological Insights From Ex Vivo Exposure of Whole Blood to PFOS and Glyphosate: Oxidative Stress and Immune Disruption

Environmental Toxicology, EarlyView.
ABSTRACT This study investigated the immunomodulatory effects of PFOS and glyphosate (GLY), both individually and in combination, on the whole blood of three ruminant species (cow, goats, and sheep) exposed ex vivo to environmentally relevant concentrations.
