RESULTS Based on visual observations, all test solutions were clear and colorless. Mortalities were 0, 0, 0. 0, 0, and 100%, respectively. The 96-hour LC50, based on nTM"-8na1 concentrations and mortality, was between 500 and 5000 mg/L. All water quality parameters were within acceptable limits. CONCLUSIONS H-21952 exhibited low toxicity in a 96-hour, unaerated, static acute test using fathead minnows, Pimeohales promelas. WORK BT: OcM. fy s W. Wetzel icology Associate /o/y/?
