Additional information

A biodegradation simulation test according to OECD guideline 303 A is regarded as not valid. It was not clarified if the substance degraded in the test system or merely bound to the sludge.  However, the substance was found to be poorly biodegradable in water in an OECD 301 B study suported by a valid QSAR estimation. It is assumed that the results of studies in water and sediment would not reveal any different findings.
