Applicant's summary and conclusion
- Conclusions:
- The detected transformation products were those in which the end of the structure of the test substance was a carboxyl group. Assessment of the likely degradants using appropriate QSAR indicated that the degradants are not of concern for PBT and vPvB properties.
- Executive summary:
LC/MS analysis using reversed phase column was performed to confirm whether any transformation products were detected in the organic and DOC phase of the Day 28 [Sludge + test substance] incubates.
In the [Sludge + test substance]-1, 2 in the organic phase, new peaks derived from transformation products were detected at retention time of approximately 2.3-4.5 min at positive mode and approximately 3.0-4.5 min at negative mode. The detected transformation products were those in which the end of the structure of the test substance was a carboxyl group.
The detected transformation products were those in which the end of the structure of the test substance was a carboxyl group. Assessment of the likely degradants using appropriate QSAR indicated that the degradants are not of concern for PBT and vPvB properties.
