Additional information
The aquatic toxicity data used for PNEC derivation are taken from a read across with the source chemical ACHP (refer also to read across justification attached to section 13).
Conclusion on classification
CLP Regulation:
Acute toxicity:
The 96-hour LC50 value of 0.0505 mg/L for acute toxicity to fish triggers classification for acute (short-term) aquatic hazard (Category Acute 1, H400) with an M-factor of 10 in accordance with Regulation (EC) No 1272/2008.
Chronic toxicity:
The EC10 value of 55.5 µg/L for fish triggers the classification for long-term aquatic hazard into Category Chronic 2 (for rapidly degradable substances), H411, in accordance with Commission Regulation (EU) No 286/2011. No classification based on the acute data is applicable as the substance is readily biodegradable and the log Kow is < 4.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
