Description of key information
With high probability acutely not harmful to aquatic algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 98.5 mg/L
Additional information
In a 72-hour static GLP test with the green alga Scenedesmus subspicatus (new name: Desmodesmus subspicatus) according to EU method C.3 the algae toxicity of the substance was investigated. Statistical evaluation of the endpoint growth rate revealed an EC50 (72h) of >100 mg/L, the EC10 was estimated to be 98.5 mg/L related to the analytically verified nominal concentration, respectively.
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).
