Description of key information
Most sensitive data (with background correction) on chronic single-species toxicity tests for different plant species are summarised in the EU-RAR (2008). According to these data, the effect concentrations for Nickel hydrogencitrate were calculated:
Hordeum vulgare: EC10 (4d, root length) = 100.7 mg Trinickel Dicitrate/kg dw
Lycospersium esculentum: EC10 (28d, yield of shoots) = 34.6 mg Trinickel Dicitrate/kg dw
Spinacia oleracea: NOEC (30d, yield of shoots) = 40.9 mg Trinickel Dicitrate/kg dw
Avena sativa: EC10 (150d, yield of grains) = 56.7 mg Trinickel Dicitrate/kg dw
Medicago sativa: EC10 (83d, yield of tops) = 151.0 mg Trinickel Dicitrate/kg dw
Raphanus sativus: NOEC (30d, yield not further specified) = 276.9 mg Trinickel Dicitrate/kg dw
Allium cepa: EC10 (56d, yield not further specified) = 188.8 mg Trinickel Dicitrate/kg dw
Trigonella poenumgraceum: EC10 (56d, yield not further specified) = 308.4 mg Trinickel Dicitrate/kg dw
Lolium perenne: EC10 (56-64d, yield not further specified) = 406.0 mg Trinickel Dicitrate/kg dw
Lactuca sativa: EC10 (63d), yield of leaves) = 107.0 mg Trinickel Dicitrate/kg dw
Zea mays: EC10 (45-50, no data) = 185.7 mg Trinickel Dicitrate/kg dw
Key value for chemical safety assessment
Additional information
Data on single-species toxicity tests resulting in L(E)C10/NOEC values for plants are summarised in Table 3.2.3-1, given in the EU-RAR, 2008 (see attachment). Values selected for the effects assessment are underlined. In the total risk approach 68 individual high quality L(E)C10/NOEC values (for 11 different species) are selected ranging from 11.0 mg Ni/kg for Lycopersicum esculentum to 1,127 mg Ni/kg for Hordeum vulgare (corresponding to 34.6 and 3547 mg Trinickel Dicitrate/kg dw). Detailed data for the lowest value for Lycopersicum esculentum were not public available, so only the most sensitive data, which were public available, could be shown 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).
