Description of key information

Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.



Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
20.3 mg/L

Additional information

A key study on the growth of Pseudomonas putida conducted similar to DIN 38412-resulted in a 16 -h NOEC of 20.3 mg A.I./L (pH-adjusted, Bringmann and Kuehn in 1977). Based on the available experimental data, it can be concluded, that depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.
