Acute and chronic toxicity of sodium sulfate to four freshwater organisms in water‐only exposures

The acute and chronic toxicity of sulfate (tested as sodium sulfate) were determined in diluted well water (hardness of 100 mg/L and pH 8.2) with a cladoceran (Ceriodaphnia dubia; 2‐ and 7‐d exposures), a midge (Chironomus dilutus; 4‐ and 41‐d exposures), a unionid mussel (pink mucket, Lampsilis abrupta; 4‐ and 28‐d exposures), and a fish (fathead minnow, Pimephales promelas; 4‐ and 34‐d ...
