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, conclusive but not sufficient for classification.
