Influence of dissolved organic carbon on the acute toxicity of copper to white sturgeon (Acipenser transmontanus) and the cladoceran (Ceriodaphnia dubia)-Data

This dataset characterizes the acute toxicity of copper and zinc to white sturgeon (~30 days post hatch) and cladocerans (less thab 24 hours old) in waters with varying dissolved organic carbon (DOC) by conducting 96-hour white sturgeon and 48-hour cladoceran copper and zinc exposures in test waters with natural DOC (from pond water) at concentrations ranging from 0.5 to 5.5 mg%
