Applicant's summary and conclusion
- Executive summary:
A study was performed to assess the toxicity of the test substance to bacteria.
The study was conducted in accordance with Council Regulation (EC) No 440/2008, Method C.11 "Activated sludge respiration inhibition" (2008). This test method is equal to OECD Guideline 209 (1984).
The activated sludge was exposed to the test substance at different concentrations. The respiration rate of each mixture was
determined after aeration periods of 3 hours.
The test substance showed 0.0 % respiration inhibition of activated sludge at a test item concentration of 1000 mg/L.
The EC50 is higher than 1000 mg/L.
The effect value relates to nominal concentration, since no analytical monitoring was performed
