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 effort involved intensive chronic toxicity testing of major ion salts (comprised of Na, K, Ca, Mg, Cl, SO4, HCO3/CO3) with the cladoceran, Ceriodaphnia dubia, a species known to be relatively sensitive to ion enrichment. This is the fourth in a series of manuscripts discussing the sensitivity of this species to major ions, with a specific focus of determining whether the principles governing acute response of this species to major ions also predict chronic responses. Results show this to be true, with acute-chronic ratios that are fairly consistent across different major ions, and responses to binary mixtures that show the same types of joint toxicity profiles as was observed previously for acute toxicity of major ions to this species. Mathematical models describing the response of these organisms were developed to predict the toxicity of major ion mixtures based on either chemical activity or chemical concentrations of ions in the mixture. These models showed good agreement with independent literature data on the chronic toxicity of major ion salts or ion mixtures to C. dubia. The datasets associated with this effort provide effect concentrations (EC20 and EC50) for 60 chronic toxicity tests conducted as part of this research, along with literature data extracted for comparison with model predictions. Data generated in this effort will inform efforts by OW, Regions, States, and Tribes to develop water quality standards/criteria for specific major ions (e.g., Cl, SO4). Perhaps more importantly, it provides part of the necessary scientific underpinning for developing standards/criteria that are sensitive to the specific composition of different sources of ion enrichment (e.g., produced water, mine drainage, irrigation return, industrial/municipal effluents) and can therefore support development of robust, integrated assessment tools.

This dataset characterizes sensitivity of fathead minnow and a unionid mussel to elevated major ions in produced water from oil and gas extraction process.

This collection consists of a series of data sets assessing the sensitivity of the adult coral, Acropora millepora, to three individual dissolved aromatic compounds (toluene, naphthalene and 1-methylnaphthalene). Physico-chemical data, hydrocarbon analysis data, and coral survival and growth response data were collected during ecotoxicity tests performed at the Australian Institute of Marine Science (Townsville site).
