Description of key information

Toxicity to aquatic algae expressed as the 72h-EC50 (growth rate) was 25.1 mg/l. The 72h NOEC (growth rate) is 6.3 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
25.1 mg/L
EC10 or NOEC for freshwater algae:
6.3 mg/L

Additional information

The toxicity of Ethyllinalool towards Scenedesmus subspicatus was investigated according to OECD Guideline 201 under GLP. Since the concentration of the test substance decreased during the experiment, toxicity values are based on measured end concentrations. The 72h EC50 (growth rate) was found to be 25.1 mg/l, The 72h NOEC (growth rate) was found to be 6.3 mg/l.
