Applicant's summary and conclusion

Conclusions:
The half life of 4-fluoroaniline in air is estimated to be 0.46 days. 4-fluoroaniline shows very less dispersion into air under normal conditions. It has 1% partitioning in air.
Executive summary:

The atmospheric oxidation half-life of 4-fluoroaniline was estimated using the level III multimedia model. It was estimated that the substance is non persistent in air medium as the half life period of 4-fluoroaniline in air is only 0.46 days. Also, the percentage of 4-fluoroaniline in air medium is 1%. 4-fluoroaniline shows very less dispersion into air under normal conditions.
