Description of key information

In a 3-hr acute toxicity study sewage sludge  microorganisms were exposed to the test item at nominal concentrations of 0, 12.3, 37, 111, 333 and 1000 mg/L in accordance with OECD 209. The EC50 value based on respiration rate after was 100 mg/L (95 % confidence limits 71.4 - 153.7 mg/L) after a 3 h contact time. The EC10 was determined as 1.1mg/L. This toxicity study is classified as acceptable and satisfies the guideline requirements for OECD 209 toxicity study.
