Results and discussion

Percent distribution in media

Water (%):
100

Any other information on results incl. tables

Over time, the substance will preferentially distribute into the compartment water (100%).

The substance will be ionized under environmentally relevant conditions, therefore, the distribution into water seems realistic .
