Description of key information

A study equivalent or similar to EU Method C.11 and OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test, according to Bringmann-Kuehn) was carried out. Pseudomonas putida was exposed to nominal test item concentrations ranging from 15.63 - 500 mg/L over a period of 16 hours. The EC10 determined was 88 mg/L, the EC50 was 120 mg/L. 

Key value for chemical safety assessment

EC50 for microorganisms:
120 mg/L
EC10 or NOEC for microorganisms:
88 mg/L
