Description of key information
Key study: OECD 201. GLP study. The ECr50 (based on growth inhibition rate) of the test item in green algae was > 1.54 mg/L after 72 hours of exposure. The ErC10 and NOEC were > 1.54 and 0.76 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 1.54 mg/L
- EC10 or NOEC for freshwater algae:
- 0.76 mg/L
Additional information
Key study: The green algae growth inhibition test was performed according to OECD Guideline 201 (GLP study). Based on preliminary results, the initial density of 1 x 10E4 cells/mL Pseudokirchneriella subcapitata were exposed up to 1.61 mg/L (in the filtrate of a loading of 100 mg/L, highest achievable concentration) for 72 hours under static conditions. The ErC50 (based on growth inhibition rate and geometric mean measured concentration) of the test item in green algae, basede on growth inhibition rate and geometric mean measured concentrations, was 1.54 mg/L after 72 hours of exposure. The ErC10 and NOEC were > 1.54 and 0.76 mg/L respectively.
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.
