Description of key information
Additional information
Discussion (screening testing)
The key study is an activated sludge die-away biodegradation test using non-adapted and adapted activated sludge. This study resulted in a rapid degradation of the test substance in particular under abiotic and non-adapted conditions, indicating that the substance itself is rapidly degraded. However as almost no mineralisation was observed and the substance was not readily biodegradable in standard tests on ready biodegradation, further investigations on the degradation products are proposed. In a first approach the substance can be regarded as inherently biodegradable.
The following information is taken into account for any hazard / risk / persistency assessment:

Soil:
From the simulation testing it appears that the substance undergoes rapid primary degradation. The registrant is at present looking into the degradation product formation and has planned degradation tests.
