Description of key information

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

Key value for chemical safety assessment

Additional information

The respiration rate of microorganisms in the presence of the substance was examined with a guideline compliant test which was conducted according to DIN 38412, part 27. Test organisms of the species Pseudomonas putida were exposed to the substance for 30 minutes. At test termination an EC20 of >1000 mg/l was determined.

In another guideline study according to DIN 38412, part 8, the inhibition of the substance on the growth rate of pseudomonas putida was examined. After 17 h an EC10 of 625 mg/L (nominal) could be determined.
