Smelter slag, containing copper and other trace elements, is widespread in riverbed sediments in the Upper Columbia River near Kettle Falls, WA. To evaluate the potential risk to aquatic life, concentrations of copper and other trace elements were measured in the shallow pore and surface water collected near the sediment-water interface. An in situ pore-water profiler was used to collect a suite of four water samples from above, at, and below the sediment-water interface at each of 11 sampling locations. Samples were collected between July 19-21, 2017. The analysis of water samples included specific conductance, pH, alkalinity, dissolved organic carbon, and a suite of major anions, cations, and trace elements.

Smelter slag containing copper and other trace elements is widespread in riverbed sediment of the upper Columbia River (UCR) of the United States. To evaluate potential risk to aquatic life concentrations of copper and other trace elements were measured in shallow pore-water and in river water samples collected near the sediment-water interface. Samples were collected using an in-situ pore-water profiler to collect a suite of four water samples from above, at, and below the sediment-water interface at each of 29 sampling locations; pore-water collected with a drive-point sampler at 10 additional locations; and Stabilized Liquid Membrane Device samplers (SLMDs) to allow determination of trace-element concentrations directly at the sediment-water interface at 8 locations. Samples were collected between April 26 and August 5, 2015 from a total of 47 locations in the UCR between river-mile 715 and 745. The analysis of water samples included specific conductance, pH, alkalinity, fluoride, chloride, bromide, nitrate, sulfate, phosphate, dissolved organic carbon, silver, aluminum, arsenic, barium, beryllium, bismuth, calcium, cadmium, cerium, cobalt, chromium, cesium, copper, dysprosium, erbium, europium, iron, gallium, gadolinium, germanium, holmium, potassium, lanthanum, lithium, lutetium, magnesium, manganese, molybdenum, sodium, niobium, neodymium, nickel, phosphorus, lead, praseodymium, rubidium, antimony, scandium, selenium, silica, samarium, strontium, tantalum, terbium, thorium, titanium, thallium, thulium, uranium, vanadium, tungsten, yttrium, ytterbium, and zinc. The analysis of SLMD samples included cadmium, copper, nickel, phosphorous, and zinc.

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/L.

This dataset contains concentrations of 25 organochlorine pesticides, 6 industrial or personal care products, 6 polybrominated diphenyl ether (PBDE) flame retardant congeners, and 15 polychlorinated biphenyl (PCB) congeners in brain, muscle, gonad, and liver tissues of white sturgeon (Acipenser transmontanus). All concentrations are reported on a wet-weight basis. Fish samples were collected from the Columbia River directly adjacent to and immediately downstream from the Hanford Site in Washington State. The site was used as a weapons-grade plutonium plant from 1944 to 1987, at which time liquid effluents were discharged directly into the Columbia River. Contaminants from past and present waste leaks from the Hanford Site can accumulate in fish residing in the Columbia River. However, contaminants from additional sources (mining, smelting, pulp and paper production, agricultural runoff, atmospheric deposition, and permitted municipal and urban discharges) can also accumulate in fish residing in the river. The sturgeon individuals sampled for this dataset were used to assess the nature and extent of non-radionuclide chemical contamination in fish in the Columbia River at the Hanford Site. Tissues from 16 individual fish were composited into 5 samples to meet the mass requirements for the chemical analyses.

Historical lead mining in Madison County, Missouri, USA has left a legacy of metals contamination. Laboratory studies were conducted to examine the effect of water hardness and age of crayfish on the toxicity of environment-based metals mixture. Additionally, the effects of chronic exposure to a metals mixture to egg development in adult crayfish were assessed. These data are comprised of measurements of elements (i.e., cobalt, nickel, copper, zinc, cadmium, lead), major anions (e.g., chloride, sulfate), dissolved organic carbon, and major cations (e.g, sodium, calcium, magnesium) in water samples collected during laboratory-based diluter exposure studies. Measurements of elements (i.e., cobalt, nickel, copper, zinc, cadmium, lead) in tissue samples (crayfish whole bodies, ovaries, leaves, feed) collected during laboratory-based diluter exposure studies are also provided.
