Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The lowest toxicity values (corrected, where appropriate, for standardised organic matter content of 3.4% and a conversion factor of 1.13 for transforming results from a dry weight to wet weight basis) are as follows: Acute toxicity to earthworms 14 d LC50= 26 mg/kg dw= 23 mg/kg ww (Eisenia foetida) Chronic toxicity to57 d NOECrepro = 3.3 mg/kg dw= 2.9 mg/kg ww earthworms (Eisenia foetida) Toxicity to plants NOECemergence= 19 mg/kg dw= 17 mg/kg ww (Mustard, Sinapis alba) Toxicity to soil micro-organisms 28 d NOEC≥ 128 mg/kg ww (nitrifying micro-organisms in sandy loam soil) The availability of a data set that includes acceptable results from three long-term tests with species from at least three trophic levels, means that it is possible to derive a PNECsoil from the test data by applying an assessment factor of 10 to the lowest chronic NOEC. The resultant PNECsoil is 3.3/10 = 0.33 mg/kg soil dry weight.
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.
