*Mobility of vanillin in soil:
Vanillin concentration (µg/kg) in the soil with time at sludge application rate of 448 144 kg/ha containing 1130 µg of vanillin per kg of sludge:

Mobility of vanillin in crop:
In the control plots, among root and stalk, only the lower stalk contained 5.3 mg/kg vanillin. Root samples from the 448 144kg/ha plots
contained 3.6 mg/kg vanillin; lower stalks contained 2 mg/kg and upper stalk did not contain any detectable compounds. Vanillin detection both
in control and samples indicates natural production.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
