Additional information
Conclusion on classification
The most sensitive value for species investigated in acute studies, algae turned out as most sensitive species (EC50 = 11.8 mg/L). This resulted in no classification and labelling for acute effects in the evironment. Based on availiable chronic data, Daphnids turned out as the most sensitive species with an EC10 of 0.521 mg/L. Therefore, the chronic classification for effects on the envrionment resulted in Aquatic Chronic 3.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
