Conclusion on classification

With a lowest long term NOEC of 0.955 mg/l (chronic value for Daphnids) and with the availability of short term and chronic values for three trophic levels, while not being readily biodegradable, this substance must be classified for aquatic toxicity category chronic 2, GHS pictogram dead fish (GHS09), no signal word and H411: Toxic to aquatic life with long lasting effects.
