The primary goal of the proposed research is to evaluate selenium and atrazine exposure and effects to fish, amphibians, and waterfowl that utilize the Refuge. The following subordinate objectives will be met to investigate selenium exposure and effects to wildlife on the Refuge: 1.Measure selenium concentrations and total organic content in Refuge sediments. 2.Measure total recoverable selenium in Refuge water. 3.Measure selenium concentrations in refuge biota including, whole body fish, waterfowl food items (invertebrates and plants) and duck eggs. 4.Assess potential adverse effects of selenium exposure to Refuge wildlife by comparing biota tissue concentrations to effects concentrations established in the literature.
