Justification for type of information:
According to column 2 of Annexes IX and X, further testing on biodegradation should be considered if the chemical safety assessment indicates the need to investigate further the degradation of the substance and its degradation products. Based on the screening study conducted with BPA PO it was concluded that the substance is not readily biodegradable but can be concluded to be inherently biodegradable. Furthermore the results from the CSA do not trigger a need for further investigation of biotic degradation as risk for the soil compartment are acceptable in every scenarii. With respect to PBT/vPvB properties the substance is not considered PBT/vPvB and therefore further testing on biodegradation is not triggered. In accordance with column 2 of Annexes IX and X, no further biodegradation testing in soil is needed.
