The substance is not rapidly biodegradable. The determined acute and chronic effect values were < 1 mg/L. Daphia magna was identified as the most sensitive species with an EC50 (48 h) of 0.09 mg/L (meas. geom. mean). The classification was made according to the most stringed outcome and the substance was classified as Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410), according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
The M-factor derived for acute aquatic hazard classification was also applied to the long-term aquatic hazard classification.
M-factor acute: 10
M-factor chronic: 10
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
