Assessment Of Selenium And Atrazine Exposure And Effects To Wildlife At The North Platte National Wildlife Refuge, Scottsbluff, Nebraska, Matthew S. Schwarz, Christina D. Lydick
United States Fish and Wildlife: Staff Publications
This study evaluated selenium and atrazine exposure and effects to fish and wildlife at North Platte National Wildlife Refuge (Refuge) in Scotts Bluff County, Nebraska. Atrazine was detected in 2 of 54 water samples and at low concentrations that are not of concern. However, concentrations of selenium and strontium exceeded toxicity guidelines in water, sediment, invertebrates, whole-body fish and wood duck eggs. Concentrations of selenium in water at Refuge sites frequently exceeded a 2 μg/L total recoverable threshold for selenium bioaccumulation and were greatest at Stateline Island (9.7 μg/L) and Little Lake Alice (24 μg/L). In sediments, strontium concentrations were …
