Description of key information
In a 3-h acute toxicity test, activated domestic sewage sludge were exposed to HDI Uretdion at nominal concentrations of 1000, 1800, 3200, 5600, 10000 mg/L. 3, 5-dichlorophenol was used as reference material at 20 and 1000 mg/L (nominal concentration). The study was performed according to the OECD Guideline No 209. The 3h-EC50 value was determined to be 5560 mg/L (based on nominal concentrations) (BIS, 2006).
This study is classified as acceptable and satisfies the guideline requirements for toxicity to microorganisms study with Activated Sludge.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 5 560 mg/L
