Description of key information
The substance is toxic to aquatic life with long lasting effects (toxicity range > 1 to ≤ 10 mg/L)
Additional information
Justification for classification or non-classification
Adequate chronic toxicity data are not available and the substance is not rapidly degradable; therefore, the aquatic toxicity assessment and classification are based mainly on the short-term toxicity data available on the substance. According to the CLP Regulation (EC 1272/2008), acute aquatic toxicity is normally determined using a fish 96-hour LC50, a crustacean species 48-hour EC50 and/or an algal species 72- or 96-hour EC50. The acute toxicity tests to invertebrates and to aquatic algae fixed the effect levels within the range > 1 to ≤ 10 mg/L.
Therefore, the substance is classified only as H411 - Category Chronic 2 - according to the CLP Regulation (EC 1272/2008).
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.
