Any other information on results incl. tables

Comparing calculated values it is obviously that the absolute amount of 1,2,4-trichlorobenzene is highest for air and water in the Mackay model due to its large volume parameter for these two compartments, while distribution calculated by the Wood model considers physical-chemical properties of 1,2,4-trochlorobenzene.
