AR226-3035 DuPont HUI 822-95 HASKELL LABORATORY POR TOXICOLOGY AUD INDUSTRIAL MEDICINE STATIC, ACUTE 48-HOOK SCREENING TEST OF H-21460 Daphnie w a a , CONTINUED Based on visual observations, all solutions were clear, except for 50 mg/L which was slightly cloudy, 500 mg/L which was cloudy, and 5000 mg/L which was cloudy and white in color. Immobilities were 0, 0, 0, 0, 0, and 0%, respectively. 100% of the daphnia in the 500 and 5000 mg/L test solutions were pale in color. The 48-hour EC50, based on nominal concentrations and immobility, was greater than 5000 mg/L. All water quality parameters were within acceptable limits. CONCLUSIONS H-21460 exhibited very low toxicity in a 48-hour, unaerated, static acute test using Daohnia magna. WORE BY: Laurie D. Bouchelle Toxicology Associate Mo/Day/Year IHynpany'.Sanitized.
