Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No statistically significant differences were found between the control and the water-accommodated fraction (WAF) at a loading rate of 100 mg test item/L at p ≤ 0.05. The EC50 (72 h) was therefore determined to be higher than the tested concentration. The results of the study demonstrate that the no-observed effect concentration (NOEC) for Pseudokirchneriella subcapitata for the parameters yield and growth rate is ≥ the water-accommodated fraction (WAF) at a loading rate of 100 mg test item/L (nominal concentration).

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.
