Biological Tissue Data Used to Evaluate Selenium Hazards in the Salton Sea Ecosystem (1984-2020)

In response to the rapidly evolving conditions at the Salton Sea with the emergence of both newly formed wetland habitat and increasing hazards to wildlife, the U.S. Bureau of Reclamation and U.S. Geological Survey have funded a re-evaluation of data gaps regarding selenium concentrations in biota the region. As part of this work, selenium concentrations in biological tissue samples were compiled from published reports, public databases, and unpublished archives into a tabulated spreadsheet. Since the California Department of Water Resources summarized selenium biological data in 2005, our compilation efforts focused on the 2005 through 2020 range. The resulting dataset encompasses all records available to us from 1984 to 2020, although we did not find any selenium records after 2017. These data support the following publication: Rosen, M.R., De La Cruz, S.E.W., Groover, K.D., Woo, I., Roberts, S.A., Davis, M.J., and Antonino, C.Y., 2022, Selenium hazards in the Salton Sea environment: Summary of current knowledge to inform future wetland management: U.S. Geological Survey Scientific Investigations Report.
