  abstract     = {{It is well known that water quality parameters, such as pH, hardness, and dissolved organic carbon (DOC), play an important role in affecting the bioavailability and the toxicity of copper (Cu) to aquatic organisms. Based upon this knowledge, bioavailability models have been developed in an effort to predict toxicity. These modeling efforts include a biotic ligand model (BLM) and a multiple linear regression model (MLR). Since the development of the BLM and MLR models, additional model development and refinement efforts have been ongoing to better understand the toxicity of Cu to aquatic organisms. One topic of interest has been the sensitivity of the cladoceran, Ceriodaphnia dubia, to Cu under varying pH conditions. The objective of the study reported here was to determine the toxicity of Cu, at a pH of 6.5, 7.5, and 8.5 on the survival and reproduction of GhEnToxLab’s laboratory clone of C. dubia. The pH control in the toxicity tests was conducted using a prescribed CO2 atmosphere to maintain the pHs. Concentration response curves were compared between pH treatments with regards to reproduction (based upon the standard endpoint of number of young per original female), with EC10 values ranging from 9.6 µg/L dissolved Cu in pH 6.5 waters to 26 µg/L dissolved Cu in pH 8.5 waters. Additionally, median lethal effect concentrations (LC50) also increased with increasing pH.}},
