Data consist of sediment toxicity and chemistry measurements and results. The data dictionary for each of the three spreadsheet files containing the data are provided as a separate tab within each spreadsheet. This dataset is associated with the following publication: Barron, M., E. Moso, R. Conmy, P. Meyer, and D. Sundaravadivelu. Toxicity of sediment oiled with diluted bitumens to freshwater and estuarine amphipods. MARINE POLLUTION BULLETIN. Elsevier Science Ltd, New York, NY, USA, 163: 7, (2021).

The data is in the form of degradation of hydrocarbons over time at two temperatures and the relative abundance of bacterial taxa identified in the microcosms. This dataset is associated with the following publication: Conmy, R., M. Barron, J. Santodomingo, and R. Deshpande. Characterization and Behavior of Cold Lake Blend and Western Canadian Select Diluted Bitumen Products. U.S. Environmental Protection Agency, Washington, DC, USA, 2017.

This dataset provides concentration-response data and associated general chemistry conditions for 32 experiments consisting of 177 toxicity tests regarding the acute toxicity of individual major ion salts and binary mixtures of major ions to Ceriodaphnia dubia; it also provides LC50 estimates and the estimated chemistries at the LC50 for each toxicity test. This dataset is associated with the following publication: Erickson, R., D. Mount, T. Highland, J. Hockett, D. Hoff, C. Jenson, T. Norberg-King, and B. Forsman. Acute Toxicity of Major Geochemical Ions to Fathead Minnows (Pimephales promelas). ENVIRONMENTAL TOXICOLOGY AND CHEMISTRY. Society of Environmental Toxicology and Chemistry, Pensacola, FL, USA, n/a - n/a, (2022).

Raw data and calculation. This dataset is associated with the following publication: Deshpande, R., D. Sundaravadivelu, S. Techmann, R. Conmy, J. Santodomingo, and P. Campo. Microbial degradation of Cold Lake Blend and Western Canadian Select Dilbits in Freshwater. JOURNAL OF HAZARDOUS MATERIALS. Elsevier Science Ltd, New York, NY, USA, 352: 111-120, (2018).

These data present chemistry and toxicity results from freshwater stream sediments collected from 99 wadable stream sites across eleven states in the Midwestern U.S. as one component of a larger USGS study in the summer of 2013. This data presents a selected suite of chemistry collected at these sites (PAHs, Organochlorines, PCBs, Trace Elements, and current use pesticides) used in calculating a Probable Effect Concentration-Likely Effect Benchmark quotient mixture score for contaminants measured in sediments. The toxicity data presents results of toxicity tests following ASTM and US EPA standard methods for sediment toxicity tests with the amphipod Hyalella azteca (28-d exposure), the midge Chironomus dilutus (10-d), and at fewer sites, with the freshwater mussel Lampsilis siliquoidea (28-d).

This dataset concerns the development of models for describing the acute toxicity of major ions to Ceriodaphnia dubia using data from single salt tests and binary mixture tests described in two other datasets under this research effort. It provides the data used in model development in the associated journal article. It also provides concentration-response data and associated general chemistry conditions for 3 experiments consisting of 14 toxicity tests on more complex mixtures of major ions based on data regarding elevated major ions in effluents and receiving waters, which was used for testing the models. . This dataset is associated with the following publication: Erickson, R., D. Mount, T. Highland, R. Hockett, D. Hoff, T. Norberg-King, and K. Peterson. The acute toxicity of major ion salts to Ceriodaphnia dubia: III. Mathematical models for mixture toxicity. ENVIRONMENTAL TOXICOLOGY AND CHEMISTRY.
