Additional information
Conclusion on classification
Based on the lowest acute EC50/LC50 value of 0.21 mg/L and the ErC10 of the Daphnia reproduction test of 0.059 mg/L and the fact that the registered substance is not readily biodegradable, classification is needed according to the recent CLP guidance documents. The substance is classified as Acute Category 1 and Chronic Category 1.
