Key value for chemical safety assessment

Additional information

The changes in the respiration rate of activated sludge in the prescence of the test substance was investigated in a GLP guideline study according to OECD 209 [BASF AG 2002]. The respiration rate was not affected after the 30 minute exposure period up to a substance concentration of 1000 mg/L (nominal).
