Description of key information

The activated sludge resiration inhibition of the test substance, TM 11-213, was assessed according to OECD Test Guideline 209 using an Activated Sludge, Respiration Inhibition Test (Carbon and Ammonium Oxidation) method. The effect of the test item on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 value of between 100 and 1000 mg/L.

Key value for chemical safety assessment

EC50 for microorganisms:
100 mg/L
