Description of key information
One long-term (21-day) toxicity study was performed to assess the toxicity of DAA to Daphnia magna (Mitsubishi Chemical Safety Institute, Ltd., 1997). The effect of 21 -day exposure on reproduction of Daphnia magna was conducted in a semi-static system according to OECD TG 211, and conducted under GLP. A limit test was performed at 100 mg/L. pH varied between 7.5 and 8.0, dissolved oxygen concentration was between 6.1 and 8.2 mg/L and the temperature was 20 ±1 °C. The mean cumulative number of juveniles produced per parental daphnid at control and 100 mg/L groups were 86 and 80 animals for 21 days, respectively.The No effect concentration is expected to be higher than 100 mg/L.Therefore the 21 -day NOEC of 100 mg/L obtained under the conditions of the study is taken as a worst case scenario in the framework of the environmental risk assessment.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
