Applicant's summary and conclusion

Conclusions:
The PBT Profiler has estimated that 4-fluoroaniline is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life in soil, 75 days, suggest that 4-fluoroaniline is moderately persistent in the environment.
Executive summary:

The PBT Profiler has estimated that 4-fluoroaniline is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life (50% degradation) in soil, 75 days, suggest that 4-fluoroaniline is moderately persistent in the environment.
