Immobilities were 0, 0, 0, 0, 20, and 80*. respectively. Ten percent of the daphnia in the 0.5, 500, and 5000 mg/L test solutions were lethargic and at the bottom of the test vessel. The 48-hour EC50, based on nominal concentrations and immobility, was between 500 and 5000 mg/L. All water quality parameters were within acceptable limits.
