Applicant's summary and conclusion

Conclusions:
Half life period of 4-fluorophenol in Soil was observed to be 75 days which exceeds the EPA criteria of 60 days. Based on these half life values it is concluded that 4-fluorophenol is not readily biodegradable (persistent) in Soil.
Executive summary:

Based on level III fugacity model the half life period of 4-fluorophenol was estimated

Half life period of 4-fluorophenol in Soil was observed to be 75 days which exceeds the EPA criteria of 60 days. Based on these half life values it is concluded that 4-fluorophenol is not readily biodegradable (persistent) in Soil.
