Results and discussion
Effect concentrations
- Duration:
- 28 d
- Dose descriptor:
- other: nitrogen transformation
- Effect conc.:
- > 10.72 mg/kg soil dw
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- nitrate formation rate
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- During the 28-day experiments, 4-chloro-N-cyclopentylbenzylamine caused an increase in nitrate production 7 days and 14 days after treatment in a silty sand soil amended with lucerne-grass-green meal. At the end of the 28-day experiment, differences between treated soil samples and control soil samples were no longer evident. Under field conditions, this metabolite should have no meaningful influence on nitrogen mineralization.
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.
