STATIC, ACUTE 48-HOUR SCREENING TEST OF H.22274 TO Drob"^ FTE*"^ CONTINUED
RESULTS Based on visual observations, the water control solution was clear and had no color. The 0.5,1.0, and 50 mg/L test solutions were clear and had no color. The 500 and 5000 mg/L test solutions were cloudy, white in color. Inunobilities were 0.0,0,0,40, and 100%, respectively. The 48-hour EC50, based on nominal concentrations and immobility, was 500 and 5000 mg/L. All water quality parameters were within acceptable limits. CONCLUSIONS H-22274 exhibited low toxicity in a 48-hour, unacrated. static acute test using Dachma fflagna.
