Description of key information
Key study: OECD 201 and EU method C.3. GLP study.
Exposure of Pseudokirchneriella subcapitata to the test item gave the following results based on nominal test concentrations:
EC50 (growth rate) = 0.21 mg/L (95% Confidence Limits = 0.19 -0.23 mg/L)
NOEC (growth rate) = 0.125 mg/L
Exposure of Pseudokirchneriella subcapitata to the test item gave the following results based on the geometric mean measured test concentrations:
EC50 (growth rate) = 0.17 mg/L (95% Confidence Limits = 0.15 -0.19 mg/L)
NOEC (growth rate) = 0.086 mg/L
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 0.17 mg/L
- EC10 or NOEC for freshwater algae:
- 0.086 mg/L

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.
