Description of key information

The 72-hour EC50 for Pseudokirchneriella subcapitata exposed to 3-methoxybutyl acetate is > 70 mg test item/L. 

Key value for chemical safety assessment

Additional information

One study is available, a 72 -hour test with Pseudokirchneriella subcapitata (IBACON, 2010). This study is GLP compliant and follows OECD guideline 201 and EC Guideline C3. Five concentrations were tested, as well as a control, with three replicates for each concentration and six replicates for the control. Concentrations were measured analytically and as the concentration of the test item was not maintained over the course of the test, mean measured concentrations were reported. This study is considered reliable and suitable for use as a key study for this endpoint.
