Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
EC50 (72 h) > 16 mg/L and NOEC (72h) = 16 mg/L both for the biomass and the growth rate.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 16 mg/L
Additional information
The potential of the test substance to induce toxicity to aquatic algae and cyanobacteria was investigated on Desmodesmus subspicatus in accordance with the EU method C.3 (92/69/EEC). 84 % of the initial concentration was loss during the test. The loss of the test substance may be attributed to the light sensitive nature of the substance and/or incorporation into the algal biomass.
EC50 (72 h) > 16 mg/L and NOEC (72h) = 16 mg/L both for the biomass and the growth rate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
