Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations. No toxic effects occur in the range of solubility.

Key value for chemical safety assessment

Additional information

Short term respiration test (OECD 209):

In a short term respiration test according to OECD guideline 209, no respiration inhibition of domestic activated sludge was observed over a period of 3 hours at 100 mg/L test substance concentration (CIBA-GEIGY 1989). Therefore, the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
