Description of key information
The 3-hour EC50 value for inhibition of respriation of activated sludge was 237 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 237 mg/L
- EC10 or NOEC for microorganisms:
- 51 mg/L
Additional information
Experimentally an IC50 of 237 mg/l and an EC10 of 51 mg/l (activated sludge) was determined in a test according to ISO guideline 8192 -1986 (E), which largely resembles the OECD guideline No. 209. The test system was validated using 3,5-dichlorophenol as reference substance.
