Acute toxicity of cadmium and sodium pentachlorophenate to daphnids and fish
When estimating the toxicity of effluents it is desirable to use organisms sensitive to a wide range of pollutants. Currently, the US Environmental Protection Agency (US EPA) recommends the use of Daphnia pulex, Daphnia magna, and Pimephales promelas to assess the toxicity of freshwater effluents. Ceriodaphnia sp. has also received increased attention as a standard toxicity test organism due to its sensitivity, short generation time, and ubiquitous distribution. Comparison of toxicity data generated by different investigators is often difficult because of differences in test procedures, dilution waters, or nutritional history of test organisms. The primary objectives of this research were to compare the sensitivity of Daphnia magna, Daphnia pulex, Ceriodaphnia reticulata, and Pimephales promelas to the reference toxicants CdCl/sub 2/ and sodium pentachlorophenate (NaPCP) and to compare results with those obtained by other investigators. A secondary objective of this study was to evaluate the effect of different dilution waters on the acute toxicity of these reference toxicants to the above test organisms.
