Nine stream sites in the Blackfoot River watershed in southeastern Idaho were sampled in September for water, surficial sediment, aquatic plants, aquatic invertebrates, and fish. Selenium was measured in these aquatic ecosystem components, and a hazard assessment was performed on the data. Water quality characteristics such as pH, hardness, and specific conductance were relatively .

of selenosis, metabolic pathways and modes of action are imperfectly understood. For example, selenium “indicator” plants can accumulate Se to concentrations of thousands of parts per million without ill effects; in these plants Se promotes growth, whereas in crop plants accumulations as low as 25 to 50 ppm may be toxic. USGS Surface-Water Annual Statistics for the Nation Select sites which meet all of the following criteria: Define one or more values for each of the following site-selection criteria: -- or select new criteria.
The selenium cycle in nature demonstrating the anaerobic reduction of selenate through selenite to elemental selenium and then to selenide. The arrows on the right side were drawn thicker to indicate that the reaction rates of dissimilatory reduction are orders of magnitude more rapid than bacterial oxidation. The U.S. Geological Survey (USGS), in cooperation with the National Park Service, investigated the water quality at 15 sites (fig. 1) from February through September to identify baseline water-quality conditions and to determine if the water met standards .

Geological Survey data. Calculated from U.S. Geological Survey Data By T.F. Harms ABSTRACT Summary statistics for selenium in vegetation have been compiled from data generated by field studies conducted by the U.S.
Geological Survey during the past 22 years. The data base contains approximately 6, analyses on. Published on an annual basis, this report is the earliest Government publication to furnish estimates covering nonfuel mineral industry data.
Data sheets contain information on the domestic industry structure, Government programs, tariffs, and 5-year salient statistics for. Commercial quantities of selenium are recovered as a byproduct of the electrolytic refining of copper where it accumulates in anode residues.
Growth in consumption was driven by the development of new uses, including applications in rubber compounding, steel alloying, and selenium rectifiers. Byselenium in rectifiers had largely been replaced by silicon, but its use.

The objective of the U.S. Geological Survey/National Park Service (USGS/NPS) Vegetation Mapping Program is to develop a uniform hierarchical vegetation classification standard and methodology on a Service-wide basis and, using that classification standard and methodology, generate vegetation maps for most of the park units under NPS management.
