Description of key information

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

Key value for chemical safety assessment

Additional information

There is one guideline study on the toxicity of the substance to activated sludge available. A potential respiration inhibition induced in activated sludge by the substance was tested in compliance with OECD guideline 209. An EC50 >100 mg/L and a NOEC of >= 100 was determined after 180 minutes of incubation (RCC Ltd. 2005).
