Description of key information

In a 2 hours study of inhibition of respiration of nitrifying bacteria the NOEC was 0.5 mg/l and the EC50 3.2 mg/l.

Key value for chemical safety assessment

EC50 for microorganisms:
3.2 mg/L
EC10 or NOEC for microorganisms:
0.5 mg/L

Additional information

Studies on effects of ethylenediamine to Pseudomonas Putida, Nitrifying bacteria and Activated sludge has been performed. Of these organisms nitrifying bacteria are the most sensitive.
