Dataset consists of water and freshwater mussel concentrations of two pharmaceuticals, sertraline and acetaminophen, collected from a 14-day accumulation and 7-day elimination study. Samples (4 replicates) were collected at 0, 4, 12, 48, 96, 168, and 336 hours during the uptake phase of the exposure. Samples (4 replicates) were collected at time point 348, 360, 408, and 504 hours during the elimination phase of the exposure. Note the time points are sequential with the uptake portion of the study followed by the elimination portion of the study.

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 ranges of the DFR; and (4) potential influence of temperature on acute K toxicity to the mussel. Water quality, survival, growth, and reproduction endpoints are reported.

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 13 laboratories to evaluate the performance of a 7-d NaCl test with L. siliquoidea.
