    • Chemical and biological data from acute and chronic exposure to sodium nitrate and sodium sulfate for several freshwater organisms in water-only bioassays

    Metadata Updated: January 6, 2026

    The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in several test waters with different water quality characteristics. In addition to the individual biological data, chemical, and water quality measurements from each toxicity test are also reported. Test organisms include unionid mussels (Lampsilis siliquoidea, Villosa iris), a midge (Chironomus dilutus), fish (rainbow trout Oncorhynchus mykiss and fathead minnow, Pimephales promelas), 2 amphibians (Hyla versicolor, Lithobates sylvaticus), and an amphipod (Hyalella azteca).
