Applicant's summary and conclusion

Conclusions:
The atmospheric oxidation half life of 4-fluorophenol was estimated using level III multimedia model it indicates that 4-fluorophenol is not persistent in air medium as the half life period of phthalylsulfathiazole in air is only 1.4 days. From this it is concluded that 4-fluorophenol is rapidly phototransformed in air.
