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

IBDU at a concentration of 640 mg/l did not inhibit the growth of Pseudomonas putida when treated for 16 hours (BASF AG 1987).
