Data for the assessment of the containment pond at Canyon Mine, Arizona, 2019

These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), dissolved organic carbon, and general water quality characteristics in Canyon Mine containment pond water, sediment, vegetaiton and invertebrate samples collected in c

Chemical and biological data from acute and chronic exposure to sodium nitrate and sodium sulfate for several freshwater organisms in water-only bioassays

The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in several test waters with different water quality characteristics. In addition to the individual biological data, chemical, and water quality measurements from each toxicity test are also reported. Test organisms include unionid mussels (Lampsilis siliquoidea, Villosa

Consumption rates and total mercury concentration of food items and consumers collected at six sites on the Colorado River in the Grand Canyon, USA, 2007-2009

Mercury flux and fate (whether mercury was retained in the aquatic ecosystem or exported to the riparian ecosystem via blackfly emergence) was calculated based on animal consumption rates and total mercury concentration of diet items. Consumers and their gut contents were collected at six sites on the Colorado River in the Grand Canyon. Sites ranged from 0-367 river kilometers downstream of L...

Influence of dissolved organic carbon on the acute toxicity of copper to white sturgeon (Acipenser transmontanus) and the cladoceran (Ceriodaphnia dubia)-Data

This dataset characterizes the acute toxicity of copper and zinc to white sturgeon (~30 days post hatch) and cladocerans (less thab 24 hours old) in waters with varying dissolved organic carbon (DOC) by conducting 96-hour white sturgeon and 48-hour cladoceran copper and zinc exposures in test waters with natural DOC (from pond water) at concentrations ranging from 0.5 to 5.5 mg%

Histopathology of American kestrels (Falco sparverius) exposed to brodifacoum

This dataset describes histopathological changes in liver, kidney, heart, skeletal muscle and intestine of captive American kestrels exposed to the second-generation anticoagulant rodenticide brodifacoum (BROD). The goal of the study was to determine the toxic range of brodifacoum by feeding birds a diet containing 0.3, 1.0, or 3.0 ug BROD/g wet weight. Birds were necropsied and
