Description of key information

A study with the test item according to OECD Guideline 209 revealed an EC50 (30 min) of 59 mg/L.

Key value for chemical safety assessment

EC50 for microorganisms:
59 mg/L

Additional information

To investigate potential harmful effects of the test item on environmentally important microorganisms, a study according to OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test) was performed under GLP. When exposed to the test substance at concentrations of 10, 32, 100, 320, 1000 mg/L, the activated sludge exhibited significantly lower respiration rates. The EC50 after 30 min was determined to be 59 mg/L.
