Key value for chemical safety assessment

Additional information

There is one guideline study according to OECD guideline 209 available investigating changes in the respiration rate of activated sludge in the presence of the substance (BMG 2009).

The respiration rate was not affected after 30 minutes of exposure up to a substance concentration of > 1000 mg/l (nominal).
