Description of key information
Additional information
The classification of the aquatic toxicity is based on the CLP regulation. The immobilisation of Daphnia and algae growth rate inhibition eco-toxicity studies have been used for classifying the substance.
The acute data for determining the acute aquatic hazard shows that the 48-hr EC50 for Daphnia and the 72-hr ErC50 for algal growth inhibition is >1 mg/l. Hence, the substance does not need to be classified as an acute aquatic hazard category 1.
The substance is non-rapidly degradable.
An adequate chronic NOEC has been derived based on the algal growth rate, which is >1mg/l. This outcome does not lead to a classification.
However, the CLP regulation dictates a second trophic level assessment if there is adequate acute toxicity data available. The second trophic level is the Daphnia. Although a 48-h NOEC has been determined, this NOEC is not chronic and hence the acute toxicity (EC50) has to be used. The 48-h EC50 for Daphnia is between 10-100 mg/l. This EC50 is taken forward in determining the long-term classification, leading to a long-term aquatic hazard category 3.
Since the most stringent outcome determines the classification, the substance is a chronic aquatic hazard category 3.
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.
