Description of key information

The partition coefficient of the test material has been determined to be:
Mean log Pow: > 6.20
Partition coefficient (Pow): >1.59 x 10^6

Key value for chemical safety assessment

Log Kow (Log Pow):
6.2

Additional information

The dead time was determined by measuring the retention time of thiourea (purity > 99%, 29 mg/l solution in methanol).

As the test material had a strong affinity for the HPLC column, the mobile phase composite was increased by means of a gradient elution to 100% methanol after the approximate retention time of DDT to elute the test material from the column.

The partition coefficient of the test material has been determined to be:

Mean log Pow: > 6.20

Partition coefficient (Pow): >1.59 x 10^6
