Additional information

The ready biodegradability of the substance was tested in a guideline study performed according to OECD 301 A using domestic activated sludge as inoculum. By measuring the DOC removal a degradation rate of 60 – 70 % was determined after 28. The incubation time was extended to 49 days and the degradation rate increased to 70 – 80 % (BASF AG, 1997).
