Administrative data
Link to relevant study record(s)
Description of key information
Two studies available.
Toxicity to aquatic algae and cyanobacteria.001:
ErC50 = 72.3 mg/L
NOEC = 12.4 mg/L
Toxicity to aquatic algae and cyanobacteria.002
ErC50 = >54.98 mg/L
NOEC = 0.93 mg/L
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 72.3 mg/L
- EC10 or NOEC for freshwater algae:
- 12.4 mg/L
Additional information
Both available studies were conducted according to recognised test methods and in accordance with GLP. One study report is only available in French, with only an English summary, and only gives a limit value for ErC50, whereas the other is fully available in English and gives a definitive value for ErC50. The study that is available fully in English was also conducted much more recently (January 2009), and for these reasons this study is used for the key values for this endpoint.
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.
