The acute toxicity of major ion salts to Ceriodaphnia dubia: I. influence of background water chemistry.

ABSTRACT: The ions Na⁺ , K⁺ , Ca²⁺ , Mg²⁺ , Cl^- , SO₄^2- , and HCO₃^- /CO₃^2- (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 backgr
