Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Toxicity to aquatic algae and cyanobacteria
Administrative data

Description of key information
The lowest EC10 is for cell number (yield) which is 0.16 mg/L. The EC10 for growth rate is 0.70 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 0.16 mg/L
Additional information
The EC50 for growth rate reduction (ERC50: 0-72h) was beyond the range tested, i.e. exceeded a TWA concentration of 9.60 mg/l. The EC50 for yield inhibition (EYC50: 0-72h) was 2.4 mg/l with a 95% confidence interval ranging from 0.53 to 10 mg/l. The NOEC for growth reduction and yield inhibition was 0.064 mg/l. In this study the EC10 provides the best statistical indication of toxicity. The lowest EC10 is for cell number (yield) which is 0.16 mg/L. The EC10 for growth rate is 0.70 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.
