At 24 hours after exposure, the 50 and 500 mg/L test solutions were slightly cloudy. Mortalities were 0, 0, 0, 0 100, and 100%, respectively. The 96-hour LC50, based on nominal concentrations and mortality, was between 50 and 500 mg/L. parameters were within4acceptable limits, except for the pH levels at s p o q ^ / L .
