Additional information

The toxicity of the test substance to microorganisms was determined in a GLP-compliant study according to OECD Guideline 209 (RCC, 2005).

In this study, sludge from a local municipal sewage treatment plant receiving predominantly domestic sewage exposed to test substance concentrations of 0, 10, 32, 100, 320 and 1000 mg/L. No effects were noted up to the highest concentration tested. Based on these findings, the 3 -h IC50 was determined at > 1000 mg/L (nominal concentration).
