    • Data on the acute and chronic toxicity of sodium chloride and sodium sulfate to freshwater organisms in a low hardness water representing Louisiana water conditions

    Metadata Updated: December 11, 2025

    We determined acute and chronic toxicity of sodium chloride (NaCl) and sodium sulfate (Na2SO4) to up to 7 freshwater species of different taxa in a hardness water of 40 mg/L as CaCO3 and evaluated the effect of 4 hardness waters (15, 30, 60, and 120 mg/L as CaCO3) on acute toxicity of NaCl and Na2SO4 to 3 sensitive species tested in the acute exposures. This data release reports results from acute and chronic exposures with Ceriodaphnia dubia (cerios), Chironomus dilutus (midge), Hyalella azteca (amphipod), Hyla versicolor (gray treefrog), Lampsilis abrupta (pink mucket), Lampsilis siliquoidea (fatmucket), and Pimephales promelas (fathead minnow. Date include survival, size, and other endpoints and associated water quality measurements.
