Conclusion on classification

With a lowest long-term NOEC of 0.022 mg/l of three trophic levels (fish), and the substance not being readily biodegardable, the substance must be classified for aquatic toxicity chronic category 1 H400 with M=1.

With a lowest short term LC50 of 0.122 mg/l of three tropic levels (fish), the substance must be lcassified for aquatic toxicity acute category 1 H410 with M=1.

This is also according to the current harmonised classification.
