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.

Applicant's summary and conclusion

Executive summary:

Korte, 1986 (Wood):

The result is calculated according to Korte, 1986 (Wood) in a media with 0.01% air, 0.2% water, soil 12.2%, sediment 24.5%, susp. sediment 24.5% and biota 38.7%.
