Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No Observed Effect Concentration (NOEC) for mortality, growth, reproduction and feeding activity of the earthworm Eisenia fetida was determined to be 1000 mg test item/kg soil, i.e. the highest concentration tested.
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 1 000 mg/kg soil dw
Additional information
A 56-day test in treated artificial soil prepared according to OECD 222 (5% peat only) is available. Different concentrations of the test item were incorporated into the soil in 6 treatment groups (5 test item concentrations, control)and 4 replicates for the test item treatments and 8 replicates for the control with 10 worms each (Ganßmann, 2013). Assessment of adult worm mortality, behavioural effects and biomass development was carried out after 28 days exposure of adult worms in treated artificial soil. Reproduction rate (number of offspring) was assessed after additional 28 days (assessed 56 days after application). No Observed Effect Concentration (NOEC) for mortality, growth, reproduction and feeding activity of the earthworm Eisenia fetida was determined to be 1000 mg test item/kg soil, i.e. the highest concentration tested.
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.
