Description of key information

The 3 hour EC10 of 3-methoxybutan-1-ol is 155.0 mg/l and the EC20 is 399.3 mg/l. The 3 hour EC50 of 3-methoxybutan-1-ol could not be determined as at the highest nominal concentration of 1000 mg/l less than 50% inhibition was noted after 3 hours incubation. The 3 hour EC50 is therefore higher than 1000 mg/l under the present test conditions.

Key value for chemical safety assessment

Additional information

The study by IBACON (2009) is a 3 hour static ecotoxicity test with activated sludge, following guidelines OECD 209 and EU Method C11. 5 concentrations were tested. It is GLP compliant and is considered reliable and fully adequate for assessment.
