Selenium in water, sediment, periphyton, benthic invertebrate and fish tissues from the Kootenai River, Idaho and Montana Selenium in water, sediment, periphyton, benthic invertebrate and fish tissues from the Kootenai River, Idaho and Montana
This dataset includes analyses of selenium (Se) in water, sediment, periphyton, and benthic invertebrate and fish tissues from the Kootenai River in Idaho and Montana. The samples were collected as part of a study intended to evaluate selenium distribution and bioaccumulation in the aquatic food webs of the Kootenai River. This dataset includes complete food web sample results from our...
Fish Tissue Analysis Results, Koocanusa Reservoir, Montana, 2021 Fish Tissue Analysis Results, Koocanusa Reservoir, Montana, 2021
Montana Fish, Wildlife, and Parks (MT FWP), in collaboration with the United States Geological Survey (USGS) Wyoming-Montana Water Science Center (WY-MT WSC), Montana Department of Environmental Quality (MDEQ), and the United States Environmental Protection Agency (USEPA) collected fish from the Koocanusa Reservoir in 2021 for tissue analysis. Fish tissue collected included muscle, eggs...
Selenium concentrations in tissues of the cyprinid Sacramento Splittail of the San Francisco Estuary (2010-11 and 2017) Selenium concentrations in tissues of the cyprinid Sacramento Splittail of the San Francisco Estuary (2010-11 and 2017)
Estuaries provide critical habitat for a vast array of fish and wildlife but are also a nexus for core economic activities that mobilize and concentrate contaminants that can threaten aquatic species. Selenium (Se), an essential element and potent reproductive toxin, is enriched in parts of the San Francisco Estuary (SFE) to levels known to cause toxicity, yet the risk of Se to species...
