Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The substance had no significant effect on either emergence, or growth, or survival of the six test species at concentrations up to and including 1000 mg/kg soil dry mass. Therefore, the lowest NOEC was 1000 mg/kg soil d.w. (Förster, 2016).
Key value for chemical safety assessment
- Short-term EC50 or LC50 for terrestrial plants:
- 1 000 mg/kg soil dw
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 1 000 mg/kg soil dw
Additional information
The key value should read NOEC >= 1,000 mg/kg soil d.w. as no effect was determined up to the highest test concentration of 1,000 mg/kg soil. d.w.
For Lycopersicon esculentum an EC10 of 547 mg/kg soil d.w. was reported while the NOEC was determined to be 1,000 mg/kg soil d.w. EC10 lower than NOEC is only due to the different statistical analysis methods for both effect values. The EC10 is not reliable due to a weak dose-response relationship and large confidence limits. Therefore, the NOEC = 1,000 mg/kg soil d.w. is the relevant value to be used for this plant.
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.
