Description of key information
The inhibition of the degradation acitvity of activated sludge is not anticipated when introduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
Changes in the respiration rate of activated sludge when exposed to the read-across substance (CAS 7023-61-2) were investigated in a GLP guideline study according OECD 209. The respiration of domestic activated sludge was monitored for 3 hours. The sludge bacteria were not affected by the substance. A NOEC of >= 100 mg/l determined (BASF SE 2007).
The read-across justification is attached in chapter 13.
