Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
EC50 (72h; measured; basis: growth rate and biomass) ≥ 0.55 mg/L; NOEC (72h; measured; basis: growth rate and biomass) > 0.55 mg/L for green algae species Scenedesmus subspicatus (new name: Desmodesmus subspicatus) [EU Method C.2]
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 0.55 mg/L
- EC10 or NOEC for freshwater algae:
- 0.55 mg/L
Additional information
The acute toxicity of the test substance to aquatic algae has been determined in a test with Scenedesmus subspicatus (new name: Desmodesmus subspicatus) according to EU Method C.3. The EC50 (meas., 72h; growth rate & biomass) was ≥ 0.55 mg/L and the NOEC (meas., 72h; biomass and growth rate) > 0.55 mg/L. Hence, it can be stated that there is no toxicity in the range of the low water solubility of the test substance. Therefore, the test substance is considered not to be harmful to aquatic algae.
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.
