Description of key information
With high probability the substance is not acutely harmful to aquatic algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 160 mg/L
- EC10 or NOEC for freshwater algae:
- 65 mg/L
Additional information
The effect of the test substance on the growth of Pseudokirchneriella subcapitata was investigated over a 72 -hour period in a Klimisch 1 study conducted according to OECD Guidelines for Testing of Chemicals (2006) No 201, "Freshwater Alga and Cyanobacteria, Growth Inhibition Test". The following results were reported: EC50 (growth rate) of 160 mg/L; EC50 (yield) of 73 mg/L; EC10 (growth rate) of 65 mg/L. The test concentrations were analytically verified. Therefore, it was concluded that the substance is not acutely harmful to aquatic algae.
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.
