RS-Freetext:
Based on the model calculations (Mackay level I, v.2.11), the target  compartment for the environmental distribution of 1,4-dichlorobut-2-ene is the air.
Water:          1.77 %
Air:           98.12 %
Soil:           0.021 %
Sediment:       0.021 %
Susp. Sediment: 1.38E-04 %
Biota (fish):   1.34E-05 %
Aerosol:        7.41E-06 %
Although data of several studies with pure isomers have been combined, all Mackay calculations indicate that during equilibrium most of the  mixture will be in the gas phase, followed by water, and further by soil

and sediment
