Toxicity of arsenate and DDT to the cladoceran Bosmina longirostris

Static bio-assays to assess the acute toxicity of arsenate and DDT (representative of inorganic and organic pollutants in the Great Lakes) to the cladoceran, Bosmina longirostris, which is a significant fish-food organism in the lakes, and to Daphnia pulex, which is frequently used as a standard org...

Description
Summary:Static bio-assays to assess the acute toxicity of arsenate and DDT (representative of inorganic and organic pollutants in the Great Lakes) to the cladoceran, Bosmina longirostris, which is a significant fish-food organism in the lakes, and to Daphnia pulex, which is frequently used as a standard organism in toxicity tests but is not common in large freshwater systems such as the Great Lakes, are described. The estimated 48-hour EC50 values for both pollutants to Bosmina in softened well water and reconstituted hard water, and to D. pulex in softened well water are tabulated. Bosmina was more sensitive to both pollutants in hard water than in softened water, and was significantly more sensitive than Daphnia.
