Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Toxicity to soil macroorganisms except arthropods
Administrative data

Description of key information
Most sensitive values for different terrestrial macroorganisms except arthropods are summarised in the EU-RAR (2008). According to these data, the effect concentrations for Trinickel dicitrate were calculated. Values in brackets refered to data without background correction. The background correction was made in the EU-RAR (2008), when only nominal values were available.
Eisenis fetida: EC10 (28d, reproduction) = 149.8 mg Trinickel Dicitrate/kg dw (146.4 mg Trinickel Dicitrate/kg dw)
Eisenia veneta: EC10 (28d, reproduction) = 286.3 mg Trinickel Dicitrate/kg dw (266.4 mg Trinickel Dicitrate/kg dw)
Enchytraeus albidus: NOEC (42d, reproduction) = 566.5 mg Trinickel Dicitrate/kg dw
Lumbricullus rubellus:EC10 (6-12 w; mortality) = 2703.2 mg Trinickel Dicitrate/kg dw (2649.7 mg Trinickel Dicitrate/kg dw)
Key value for chemical safety assessment
Additional information
Data on chronic single-species toxicity tests resulting in NOEC/L(E)C10 values for soil invertebrates are summarised in Table 3.2.3-3 of the EU-RAR (2008) (see attachment of the key study record of chapter 6.3.1). Values selected for the effects assessment are underlined. In the total risk approach 21 individual NOECs (for 4 different anilids) are selected ranging from 47.6 mg Ni/kg to 1140 mg/kg for Eisenia fetida reproduction (149.8 mg Trinickel Dicitrate/kg to 3587.6 mg Trinickel Dicitrate/kg).
The detailed toxicity data for Eisenia fetida could not be shown here, because this data were not public available. So the most sensitive data for Eisenia veneta were recorded here in detail.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.
