Applicant's summary and conclusion
- Conclusions:
- It was concluded that the log Pow of test item was > 7.2 (Pow > 1.6E+07).
- Executive summary:
In the chromatogram of the test item solution, five peaks with a retention time of > 22 minutes were observed. Under the same analytical conditions, the retention time of 4,4’-DDT (log Pow = 6.5) was 10.6 minutes and for benzo[ghi]perylene (log Pow = 7.2) 17.6 minutes. It was concluded that the log Pow of test item was > 7.2 (Pow > 1.6E+07).
