Chronic toxicity of major ion salts and their mixtures to Ceriodaphnia dubia.

ABSTRACT: In previous work we intensively studied the acute responses of the cladoceran Ceriodaphnia dubia to major geochemical ions (Na⁺ , K⁺ , Ca²⁺ , Mg²⁺ , Cl^- , SO₄^2- , and HCO₃^- /CO₃^2- ), culminating in the development of models to predict acute toxicity from ionic composition. To quantitatively evaluate whether the toxicological behavior of major ions observed for C. dubia extends to chronic toxicity, we conducted 58 chronic toxicity tests with individual major salts and binary mixtures thereof. Chronic responses paralleled those demonstrated previously for acute exposure, specifically 1) similar relative toxicity of individual salts; 2) different Na salts showing similar po
