Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Experimental results are available for earthworms, collembolans and plants (Stantec, 2006). The study report only contains EC25 and EC50 values; therefore the results of these chronic studies are considered as acute effect values.
- Earthworm reproduction (no. of progeny): 63-d EC50 = 776 mg/kg soil dw
- Earthworm adult survival: 35-d LC50 > 1000 mg/kg soil dw
- Collembolan adult survival and reproduction (EC50, EC25): > 1000 mg/kg soil dw.
- Alfalfa, Barley, Northern Wheatgrass seedling emergence (EC50): > 1000 mg/kg soil dw.
The lowest effect value was detected for Alfalfa in a seedling emergence test (EC50 shoot dry mass = 1632 mg/kg soil dw). The PNEC soil was derived by applying an assessment factor of 1000 to the lowest EC50 according to REACH Guidance R.10.6.2 as results are available from short-term tests with a producer, a consumer and a decomposer. The PNEC based on experimental data is 1.63 mg/kg soil dw.
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.
