Results and discussion

Any other information on results incl. tables

Before the application, the soil samples did not contained Guaiacol.
At sludge application rate of 448144 kg/ha, only 30 µg/kg of Guaiacol was found five days after the application and in the 0-15.2 cm of sample depth. No concentrations were observed in other sample depths and later.
Guaiacol was not detected at other sludge application rate in soil and crop samples.
This study did not permit to know the fate of Guaiacol contained in sludge at soil level. According to these results, Guaiacol did not persist in soil and was not absorbed by terrestrial plants.

Applicant's summary and conclusion

Conclusions:
Guaiacol did not persist in soil and was not absorbed by terrestrial plants.
