Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations. 

Key value for chemical safety assessment

Additional information

One GLP guideline study on the respiration of microorganisms is available. The study was conducted in compliance with 87/302/EEC and investigated the respiration inhibition induced by the substance in activated sludge. Based on the respiration rate an EC20 >100 mg/l was determined after an inoculation time of 3 hours (CIBA-GEIGY 1992t).
