“…Because the models represent the combined toxicity of all seven ions, they have much broader application than ion toxicity studies based on generic measures like conductivity or TDS, or studies focusing on certain waters or ion combinations. Application of these models can reduce the need for extensive characterization and fractionation manipulations during TIE studies of high TDS waters [11]. They can also be used to project changes in toxicity resulting from modifications in industrial processes, effluent treatment, or other remedial measures.…”

“…However, many natural and anthropogenic sources can increase ion concentrations to levels toxic to aquatic life. Studies of oil and gas produced waters [3][4][5], irrigation drain waters [6,7], shale oil leachates [8], sediment pore waters [9,10], and industrial process waters [11,12] have shown toxicity caused by elevated concentrations of common ions.…”

“…For example, Burnham and Peterka [13] noted that fathead minnows could tolerate TDS concentrations up to 15,000 mg/L in Saskatchewan lakes dominated by Na ϩ and , but populations did not persist above 2,000 2Ϫ SO 4 mg/L in Na ϩ /K ϩ / -dominated lakes of Nebraska. In stud-Ϫ HCO 3 ies of irrigation drain waters, Dickerson et al [7] found Ceriodaphnia dubia 50% lethal concentration (LC50) values corresponding to approximate conductivities of 3,500 to 4,000 S/cm (calculated), while Jop and Askew [11] showed major ion toxicity to C. dubia in an industrial process water with a * To whom correspondence may be addressed. † Deceased.…”

Abstract-Toxicity of fresh waters with high total dissolved solids has been shown to be dependent on the specific ionic composition of the water. To provide a predictive tool to assess toxicity attributable to major ions, we tested the toxicity of over 2,900 ion solutions using the daphnids, Ceriodaphnia dubia and Daphnia magna, and fathead minnows (Pimephales promelas). Multiple logistic regression was used to relate ion composition to survival for each of the three test species. In general, relative ion toxicity was K ϩ Ͼ ഠ Mg 2ϩ Ͼ Cl Ϫ Ͼ ; Na ϩ and Ca 2ϩ were not significant variables in the regressions, suggesting that the toxicityof Na ϩ and Ca 2ϩ salts was primarily attributable to the corresponding anion. For C. dubia and D. magna, toxicity of Cl Ϫ , , 2 Ϫ SO 4 and K ϩ was reduced in solutions enriched with more than one cation. Final regression models showed a good quality of fit to the data (R 2 ϭ 0.767-0.861). Preliminary applications of these models to field-collected samples indicated a high degree of accuracy for the C. dubia model, while the D. magna and fathead minnow models tended to overpredict ion toxicity.

“…In the present study, the key influences of background water chemistry on the acute toxicity of major ions salts to C. dubia were the effect of Na on toxicity of K salts and the effects of Ca on the toxicity of Na and Mg salts. Although the practical implications of the Na effect on K toxicity are limited because of the unlikelihood of K‐dominated exposures, this result does mean that when K exposures are of concern effects concentrations based on typical laboratory tests with low Na concentrations would overestimate risk. Regarding the Ca effects, although a hardness dependence of toxicity was already known for some Na and Mg salts and Davies and Hall implicated Ca as the specific factor for Na 2 SO 4 toxicity, our results more thoroughly establish a role of Ca for a variety of salts.…”

The ions Na , K , Ca , Mg , Cl , SO , and HCO /CO (referred to in the present study as "major ions") are present in all freshwaters and physiologically required by aquatic organisms but can increase to harmful levels from a variety of anthropogenic activities. It is also known that the toxicities of major ion salts can vary depending on the concentrations of other ions, and understanding these relationships is key to establishing appropriate environmental limits. The authors present a series of experiments with Ceriodaphnia dubia to evaluate the acute toxicity of 12 major ion salts and to determine how toxicity of these salts varies as a function of background water chemistry. All salts except CaSO and CaCO were acutely toxic below saturation, with the lowest median lethal concentrations found for K salts. All 10 salts that showed toxicity also showed some degree of reduced toxicity as the ionic content of the background water increased. Experiments that independently varied Ca:Mg ratio, Na:K ratio, Cl:SO ratio, and alkalinity/pH demonstrated that Ca concentration was the primary factor influencing the toxicities of Na and Mg salts, whereas the toxicities of K salts were primarily influenced by the concentration of Na. These experiments also indicated multiple mechanisms of toxicity and suggested important aspects of dosimetry; the toxicities of K, Mg, and Ca salts were best related to the chemical activity of the cation, whereas the toxicities of Na salts also reflected an influence of the anions and were well correlated with osmolarity. Understanding these relationships between major ion toxicity and background water chemistry should aid in the development of sensible risk-assessments and regulatory standards.

“…We conducted various tests with Cei-iodaphnia and performed simple chemical assays to help determine other sources of toxicity in the SSBR process. Diagnostic toxicity testing with Ceriodaphnia is an effective means for identifying problematic constituents in emuents or ambient waters, or for revealing toxicity sources in wastewater treatment operations (91,92).…”
