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

EC50 for microorganisms:
100 mg/L

Additional information

A study on a close structural analogue(CAS 16090 -02 -1) is available in order to determine the toxicity of the substance to microorganisms. The study demonstrates that the substance does not inhibit the degradation activity of activated sludge in concentrations lower or equal than 100 mg/L.

It is assumed that also the substance with CAS 133-66-4 does not inhibit the degradation activity of activated sludge.
