Additional information
Conclusion on classification
There are acute data available for all three trophic levels. The lowest EC50 is for immmobilisation of daphnia at 39.7 mg/L. The substance is also "not readily biodegradabable. As such, a Classification of Aquatic Chronic 3: H413 May cause long-lasting harmful effects to aquatic life is appropriate.
