Additional information
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=100
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=100
This is also according to the current harmonised classification.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
