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

There is one valid study according to ISO 8192 available (BASF AG, 1981). The study resulted in an EC20 value of > 1995 mg/L. However the test was performed using industrial activated sludge. According to the "Guidance on information requirements and chemical safety assessment, chapter R.7b: Endpoint specific guidance, point R." industrial activated sludge is considered to be adapted to the test substance and the results can not be extrapolated to domestic activated sludge. Hence the results can not be used for a hazard assessment.
