Additional information
Conclusion on classification
As in the case of long-term/chronic toxicity, algae appear to be the most sensitive species with NOEC of 0.12 mg/L for Chlorella sp. (Johnson 2007). The maximum concentration of zinc ion in the registered substance is 16.5 %. Since the zinc concentration in the target substance is below 25 %, classification for chronic toxicity category 2 is triggered for the registered substance in accordance with Regulation (EC) No 1272/2008.
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).
