Description of key information
In a 3-h respiration inhibition acute toxicity study according to OECD 209 sewage sludge micro-organisms were exposed to the test item. The emulsifier Tween 80 was used for solving the test item in the test medium. Nominal concentrations were 10, 32, 100 and 320 mg/L. 3,5-Dichlorophenol was used as reference substance. The IC50 of the reference substance was 6.6 mg/L, the IC50 of the test item was estimated to be > 320 mg/L. No effects occured in the solvent control.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 320 mg/L
