Additional information
As a worst case assumption the reference values from Zn have been used (available in the IUCLID dossier of zinc oxide, CAS 1314-13-2). The EC50 and NOEC values Pseudokirchnerielle subcapitata were determined to be 136 and 19 µg/L respectively. Corrected for the molecular weight EC50 and NOEC values of 403 and 56 µg/L have been determined for the substance.
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.
