Abstract We examined whether the sensitivity of Ceriodaphnia dubia to copper toxicity was influenced by the hardness of the water in which they were reared or in which they were exposed. Organisms cultured in very hard water were 1.5‐fold less sensitive to copper than those in moderately hard water. However, the hardness of the exposure water had a greater (2.5‐fold) effect on copper median effective concentration (EC50s).
