The data release includes data from four studies: (1) toxicity of a permitted effluent, which entered the Deep Fork River (DFR), Oklahoma, USA, to a unionid mussel (Lampsilis siliquoidea) and to 2 standard test species (cladoceran Ceriodaphnia dubia; and fathead minnow Pimephales promelas) in short-term 7-d effluent tests; (2) relative sensitivities of the 3 species to potassium (K), an elevated major ion in the effluent, using 7-d toxicity tests with KCl spiked into a DFR upstream reference water; (3) potential influences of background water characteristics on the acute K toxicity to the mussel (96-h exposures) and cladoceran (48-h exposure) in 4 reconstituted waters that mimicked the hardness and ionic composition...

The data consists of the responses (survival, growth, and/or reproduction) of test organisms were determined in six concentrations of toxicants in 7-day toxicity tests or in four different feeding rates in 7-day feeding experiments. Specifically we evaluated the sensitivity of 2 mussel species (Villosa constricta and Lampsilis siliquoidea) and P. promelas and C. dubia using effluents in 7-d exposures. We then refined the method by determining the best feeding rate of algal mixture for 1-, 2-, and 3-wk-old L. siliquoidea in a 7-d feeding experiment, and using derived optimal feeding rates to assess the sensitivity of the 3 ages of juveniles in a 7-d NaCl test. Finally, we conducted an interlaboratory study among...
