Description of key information

EC50 (3 h) > 1000 mg/L (nominal, OECD 209)

Key value for chemical safety assessment

Additional information

One experimental study is available investigating the toxicity of the test item to activated sludge microorganisms. The study was performed according to OECD 209 (GLP) using activated sludge of a predominantly domestic sewage. 10, 100 and 1000 mg/L were tested and the respiration rate was measured after an exposure of 3 h. The test item is not expected to inhibit the degradation process in sewage treatment plants since the EC50 (3 h) turned out to be > 1000 mg/L.
