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.
