EC10 or NOEC for microorganisms:
15 mg/L

Additional information

Biodegradability of a number of analogues of the test substance has been investigated in a CO2 evolution test performed according to OECD Test Guidelines. A toxicity control, containing both test and reference substances, resulted in a biodegradation rate of 42 % after 6 days and 71 % after 28 days, demonstrating that the biodegradation of the reference substance was not inhibited by toxicity of the substance at the tested concentration of 15 - 20 mg/L.
