Any other information on results incl. tables

The Level III model predicted that 99.98% of vinyl chloride directly emitted to the atmosphere will stay in the atmosphere.  The dominant removal process is reaction with atmospheric hydroxyl radical (T1/2 = 1.5 days).  The total estimated persistence of vinyl chloride in the atmosphere is 34.2 hours.  Less than 0.02% of the emitted vinyl chloride is predicted to migrate to the water, soil, or sediment compartments.
