Key result
Type:
log Pow
Partition coefficient:
> 7.2
Temp.:
35 °C
Remarks on result:
not determinable
Remarks:
pH was not recorded as this as an HPLC method
Details on results:
Under the same analytical conditions, the retention time of 4,4’-DDT (log Pow = 6.5) was 12.5 minutes and the retention time of benzo[ghi]perylene (log Pow = 7.2) was 20.6 minutes. It was concluded that the log Pow of test item was > 7.2.
Conclusions:
It was concluded that the log Pow of test item was > 7.2.
Executive summary:

It was concluded that the log Pow of test item was > 7.2.
