Any other information on results incl. tables

1. Based on the model calculations (Mackay level I, v.2.11), 
the target  compartment for the environmental distribution of the 
neutral form of cyclohexylamine is water.
Water: 95.16 %
Air: 4.37 %
Soil: 0.23 %
Sediment: 0.24 %
Susp. Sediment: 1.5E-03 %
Biota (fish): <0.001 %
Aerosol: <0.001 %

2. Based on the model calculations (Mackay level I, v.2.11), the target compartment for the environmental distribution of the protonated form of cyclohexylamine is water.
Water: 100.0 %
Air: <0.001 %
Soil: <0.001 %
Sediment: <0.001 %
Susp. Sediment: <0.001 %

Applicant's summary and conclusion

Executive summary:

Under environmental relevant conditions (pH 4 to 9), cyclohexylamine will completely be protonated. Based on Model calculations according to Mackay Level I, the target environmental compartment for the protonated form of cyclohexylamine is water (Bayer Industry Services, 2006).
