Description of key information

The 72-hour EC50 for Pseudokirchneriella subcapitata exposed to 3-methoxybutan-1-ol is > 100 mg test item/L.  The 72 hour NOEC is 100 mg test item/L, based on growth rate and yield.

Key value for chemical safety assessment

Additional information

One study is available, a 72 -hour static test with Pseudokirchneriella subcapitata (IBACON, 2010). This is a GLP-compliant study and follows OECD Guideline 201 and EC Method C3. Five concentrations were tested, as well as a control, with three replicates per test concentration and six replicates for the control. Test concentrations were measured analytically and concentrations were maintained over the course of the test. The study is considered reliable and suitable for use as a key study for this endpoint.
