Physicochemical factors affecting the sensitivity of Ceriodaphnia dubia to copper.

The effects of physicochemical conditions, such as pH, water hardness, flow rates and natural organic substances on the sensitivity of Ceriodaphnia dubia to the toxic effects of copper were investigated using static bioassay cups and specially designed flow-through bioassay chambers. We found that C. dubia was very sensitive to pH changes and the total… (More)
