Additional information

The toxicity of the test substance to microorganisms was determined in a GLP-compliant study according to OECD Guideline 209 (CG, 1994). In this study, activated sludge from a local communal sewage treatment plant was exposed to test substance concentrations of 0, 10, 32, 100 and 320 mg/L. No inhibitory effects on respiration were noted up to the highest concentration tested. Based on these findings, the 3 -h IC50 was determined at >320 mg/L (nominal concentration).
