Additional information

Result after 24 hours

50% effective inhibitory concentration (EC50): > 10 mg/L. The highest concentration causing 0% immobility: 2.1 mg/L. The lowest concentration producing 100 % immobility: > 10 mg/L

 

Result after 48 hours

50% effective inhibitory concentration (EC50): 2.9 mg/L (95% confidence limit: 2.5-3.4 mg/L). The highest concentration causing 0% immobility: 1.5 mg/L. The lowest concentration producing 100 % immobility: 10 mg/L

On the basis of the results noted in the study, classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008 is as follows:

N; R51/53 Dangerous for the environment; Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.

Chronic aquatic toxicity, Category 2; H411: Toxic to aquatic life with long lasting effects.
