Administrative data
Link to relevant study record(s)
Description of key information
- Toxicity to aquatic algae expressed as the 96h-EC50 (growth rate) was 156.7 mg/l. The 96h-EC10 (growth rate) was 54.3 mg/l.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 156.7 mg/L
- EC10 or NOEC for freshwater algae:
- 54.3 mg/L
Additional information
The toxicity of linalool to Scenedesmus subspicatus (new name Desmodesmus subspicatus) expressed as the 96h-EC50 for growth rate was 156.7 mg/l. The 96h-EC10 was 54.3 mg/l. The test was carried out in a non-GLP study according to DIN guideline 38412 L9.
When biomass was used as parameter, the 96h-EC50 was 88.3 mg/l and the 96h-EC10 was 38.4 mg/l. The results based on growth rate are used for the hazard evaluation.
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.
