Fate of Hormones in Tile-Drained Fields and Impact to Aquatic Organisms Under Different Animal Waste Land-Application Practices

Objectives:   - Assess the relative amount of hormones discharged from tile-  drained agricultural fields under different manure and lagoon   effluent applications;   - Assess hormone persistence in fields under these application   practices;   - Evaluate the impacts of these hormone loads (relevant levels and   mixtures) on aquatic organisms.     Field monitoring studies will be conducted to evaluate hormone   discharges within in-line tile drain or stream collection and   monitoring systems associated with agricultural fields receiving   animal wastes. Natural and synthetic hormones and their primary   metabolites will be measured in manure and effluent being land-  applied and in field soils over time. Sexual differentiation and   reproduction effects will be evaluated by exposing early life-stages   of fish to hormones in controlled laboratory microcosms paired with   field studies examining similar endpoints in native populations of   fish in streams down gradient from CAFOs and in turtles inhabiting   manure retention lagoons. Population-level effects due to hormone   exposure will be estimated by fitting a population-matrix model to   measured survival and fecundity parameters.    (hormone); (hormones); (endocrine disrupting chemicals); (chemicals   of concern); (chemical of concern); (androgen); (androgens);   (estrogen); (estrogens); (pharmaceuticals); (pharmaceutical);   (CAFO); (CAFO's): (CAFOs); (controlled animal feeding operation);   (controlled animal feeding operations); (land use); (agricultural   land use)
