ErC50 (72h) > 6.83 mg/L (meas. geom mean) for Pseudokirchneriella subcapitata (OECD 201)
Aquatic chronic toxicity
Aquatic invertebrates
EC10 (21 d) = 0.027 mg/L (TWA) for Daphnia magna (OECD 211)
NOEC (21d) = 0.087 mg/L (TWA) for Daphnia magna (OECD 211)
Algae
NOEC (72h) = 2.58 mg/L (Meas. geom. mean) for Pseudokirchneriella subcapitata (OECD 201)
CLP
Based on the available data listed above, the most sensitive acute effect concentration was obtained for Danio rerio, with an LC50 (96h) = 4.3 mg/L (TWA). Thus, the substance needs not to be acutely classified according to the Regulation (EC) No 1272/2008 (CLP) and following amendments (ATPs).
The most sensitive chronic concentration was determined for Daphnia magna, with an EC10 (21 d) = 0.027 mg/L (TWA). The substance is readily biodegradable. Thus, the substance is classified and labelled as long-term aquatic hazard Category Chronic 2, according to Regulation (EC) No. 1272/2008 (CLP) and following amendments (ATPs).
M-factor for chronic aquatic toxicity: not applicable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
