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

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

Data of the structurally related molecule CAS 173011-06-8 are available for the toxicity assessment of the test substance to microorganisms.

CAS 173011-06-8: In a short-term respiration test similar to OECD 209 an EC20 of approx. 1000 mg/L was determined (BASF AG 92/1991/08/11983, 1992). Additionally, in an oxygen consumption test according to DIN 38412 part 27 using Pseudomonas putida an EC10 of >= 1000 mg/L was determined (BASF AG 92/1991/71/1, 1993).

These results are considered to be adaptable for the test substance due to the structural similarities and the identical core-molecules. Based on these values the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
