Description of key information
In an OECD guideline 201 Algal Growth Inhibition Test with Pseudokirchinerella subcapitata following accepted GLP standards, the test material was not found to inhibit growth at the highest practically attainable test concentration.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 14.8 µg/L
- EC10 or NOEC for freshwater algae:
- 14.8 µg/L
Additional information
The test substance was not found to be inhibitory to Selanastrum subcapitata at a concentration of 14.8 micrograms/l, a value greatly in excess of the limiting aqueous solubility of 212 micrograms/l under the test conditions. The 72-hour median effect concentration (EC50) was not identified but estimated to be in excess of 14.8 micrograms/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.
