Evaluating chronic toxicity of sodium chloride or potassium chloride to a unionid mussel (Lampsilis siliquoidea) in water exposures using standard and refined toxicity test methods Evaluating chronic toxicity of sodium chloride or potassium chloride to a unionid mussel (Lampsilis siliquoidea) in water exposures using standard and refined toxicity test methods
Individual measurements of toxicity and water quality data used to calculate means reported in the associated publication. The objectives of the present study were to (1) refine test conditions for improving mussel survival and growth in a long-term feeding study, (2) evaluate chronic toxicity of NaCl and KCl to fatmucket under traditional test conditions outlined in ASTM (ASTM 2017) and...
Chemical analyses and histopathology of small rodents, vegetation, and soil collected from the Kanab North breccia pipe uranium mine in the Grand Canyon watershed Chemical analyses and histopathology of small rodents, vegetation, and soil collected from the Kanab North breccia pipe uranium mine in the Grand Canyon watershed
These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in soil, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation and soil. Radioactivities...
Results from radiochemical analyses of small rodent whole bodies collected from breccia pipe uranium mines and reference locations in the Grand Canyon watershed. Results from radiochemical analyses of small rodent whole bodies collected from breccia pipe uranium mines and reference locations in the Grand Canyon watershed.
These data are comprised of measurements of gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th, Ra-226) in small rodent bodies. Samples were collected at non-mining and U breccia pipe mining sites in various production stages, in the Grand Canyon watershed.
Chronic toxicity of 4-Nonylphenol to two unionid mussels in water-only exposures-metadata Chronic toxicity of 4-Nonylphenol to two unionid mussels in water-only exposures-metadata
Chronic (28-d) toxicity of 4-nonylphenol (4-NP) to two commonly tested species of mussels: fatmucket (Lampsilis siliquoidea) and rainbow mussel (Villosa iris).
Stable carbon and nitrogen isotope values in muscle tissue of bigheaded carps and native filter-feeding fish from the lower Missouri River, USA, 2005-2006 Stable carbon and nitrogen isotope values in muscle tissue of bigheaded carps and native filter-feeding fish from the lower Missouri River, USA, 2005-2006
Fish muscle tissue was analyzed for stable carbon and nitrogen isotope values (delta 13C and delta 15N) for two filter-feeding fishes native to China, silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis), and three native filter-feeding fish including bigmouth buffalo (Ictiobus cyprinellus), gizzard shad (Dorosoma cepedianum) and paddlefish (Polyodon...

Analysis of organochlorine pesticides and polychlorinated biphenyls (PCBs) in northern cardinal eggs from six neighborhoods near Washington, DC
Chemistry data for assessment of crayfish from Madison County, Missouri lead mines 2015 Chemistry data for assessment of crayfish from Madison County, Missouri lead mines 2015
These data are comprised of measurements of metals (cobalt, nickel, copper, zinc, cadmium, and lead), anions (fluoride, chloride, nitrite, bromide, nitrate, sulfate, and phosphate), dissolved organic carbon, and major cations (sodium, magnesium, potassium, calcium, manganese, iron, and strontium) in surface and pore water samples collected during an assessment of the impacts of mining...

Geospatial locations of eDNA sampling sites in the Grand Canyon region near breccia pipe uranium mines
Female Faxonius (formerly Orconectes) quadruncus broodstock collected for toxicity testing Female Faxonius (formerly Orconectes) quadruncus broodstock collected for toxicity testing
Broodstock individual Faxonius quadruncus were collected for culturing eggs until hatch. Hatchling crayfish were used to be used in toxicity testing to assess hazards of metals mixtures to young Faxonius quadruncus
Development of a dual luciferase-fluorescamine assay adapted to a 384 micro-well plate format-Data Development of a dual luciferase-fluorescamine assay adapted to a 384 micro-well plate format-Data
We have adapted two commonly used human breast luciferase transactivation cell bioassays, the recently re-named estrogen agonist/antagonist screening VM7Luc4E2 cell bioassay (previously designated BG1Luc4E2) and the androgen/glucocorticoid screening MDA-kb2 cell bioassay, to 384-well formats for HTS of endocrine-active substances. This cost-saving adaptation includes a fast, accurate...
Missouri River Bend Classification Missouri River Bend Classification
Management actions intended to increase growth and survival of pallid sturgeon (Scaphirhynchus albus) age-0 larvae on the Lower Missouri River require a comprehensive understanding of the geomorphic habitat template of the river. The datasets described here are intended to support decisions relating to where channel-reconfiguration projects should be located to optimize effectiveness of
Asian Carp Acoustic Stimuli Data Asian Carp Acoustic Stimuli Data
Invasive silver carp (Hypophthalmichthys molitrix) occur in large regions of the Mississippi River drainage, outcompete native species, and are notorious for their prolific jumping behavior. Juvenile and adult (up to 25 kg) carp are known to jump up to 3 m above the water surface in response to moving watercraft. Broadband sound recorded from an outboard motor (100 hp at 32 km/hr) can...
