Description of key information
Additional information
The following EC50 data have been retrieved from the short-term aquatic toxicity tests:
| Organism | EC50 (mg/l) |
| Fish | 180 - 320 |
| Daphnia | 289 |
| Algae (growth) | 93 mg/l |
As for algal growth inhibition, the EC50 value falls within the bracket 10 mg/l < EC50 < 100 mg/l, and the substance furthermore proved to be not biodegradable, the substance basically fulfills the criteria for ecotoxicological classification as "Aquatic Chron. 3" H412, according to the CLP regulation, or as N; R52/53 according to the former DSD regulation. However, as a NOEC ≥ 10 mg/l has been determined during the chronic Daphnia toxicity study, the test results of the substance regarding aquatic toxicity are according GHS Annex 1, 4.1.2.6 conclusive but not sufficient for classification.
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.
