  • A Multi-Tiered Approach Using Daphnia magna to Assess Chlorpyrifos Risk to Aquatic Receptors

    Creator:
    Maggio, Stephanie A.
    Abstract:
    Chlorpyrifos (CPF) is a widely used broad-spectrum organophosphate insecticide. Following exposures, CPF and its more toxic oxon metabolite (CPFO) elicit neurotoxic effects by inhibiting the activity of the acetylcholinesterase enzyme (AChE), resulting in altered fitness and death at high doses. Following exposure, organisms bioactivate CPF to CPFO through the Cytochrome...
