Description of key information
In this study the test item Hostanox O 3 caused no inhibition on growth of the freshwater green alga Desmodesmus subspicatus after 72 hours exposure when tested with the saturated solution. The geometric mean measured NOEC for inhibition of specific growth rate and yield after 72 hours was 2.18 mg/L. All effect levels are given based on the geometric mean measured concentration of Hostanox O 3, which was analytically verified via LC-MS/MS.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 2.18 mg/L
Additional information
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.
