Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
In a static acute toxicity test with green algae (Scenedesmus subspicatus) over 72 hours inhibition of the biomass was observed. The 72h EC50 was determined to be greater than 500 mg/L, the NOEC is 500 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 500 mg/L
Additional information
In a static study the acute toxicity of the test item with green algae (Scenedesmus subspicatus) was determined. Algae were exposed over a 72-hour period to a range of 8 concentrations: 3.9, 7.8, 15.625, 31.25, 62.5, 125, 250, 500 mg/L and an untreated control. The study procedure was based on the OECD guideline 201. Results (on the basis of the nominal concentrations): EC50 after 72 hours >500 mg/L, NOEC: 500 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).
