Additional information

A reliable study according to OECD test guideline 209 with activated sludge of a predominantly domestic sewage assessing the toxicity of the registered substance to microorganisms is available. The study was conducted and documented equivalent to GLP. The test substance was applied directly (no vehicle was used) for 3h in a static freshwater system. Analytics were not performed. All validity criteria were met. The EC50 to activated sludge of the test substance was determined to be 212.3 mg/l based on the respiration rate.
