Conclusion on classification
Justification for classification for 2-Butenedioic acid (2Z)-, reaction products with ammonium di-µ3-hydroxyhexacosa-µ-oxododecaoxododecatungstate(6-) (6:1), ammonium octa-µ-oxodi-µ3-oxo-µ4-oxododecaoxoheptamolybdate(6-) (6:1), nickel(2+) nitrate (1:2) and nickel(2+) sulfate (1:1)
Brief description of the data relevant for classification:
Degradation
Biodegradation: the substance is an inorganic complex metal material and therefore non-biodegradable. The concept of degradability as applied to organic compounds has no meaning.
Solubility and transformation:
At room temperature and pH 6.6 – 6.8, the maximum dissolved metal ions concentrations for the loading in the range of 50 – 1000 mg/L are measured as below:
W: 15.99 – 100.65 mg/L
Mo: 3.67 – 48.2 mg/L
Ni: 7.15 – 38.62 mg/L
Further information on environmental transformation is not available.
Acute aquatic toxicity
For fish: LL50(96 h) (Danio rerio): > 100 mg/L (nominal, WAF)
For aquatic invertebrates: EL50(48 h) (Daphnia magna): 36 mg/L (nominal, WAF)
For algae/aquatic plants: ErL50(73 h) (Desmodesmus subspicatus): 2.3 mg/L (nominal, WAF)
Chronic aquatic toxicity
For algae/aquatic plant: NOERL(72 h) (Desmodesmus subspicatus): 0.36 mg/L (nominal, WAF)
In comparison with the acute aquatic toxicity values of the compound tested as such and the dissolved metal ions concentrations, the substance is considered as readily soluble according to the guidance on the application of the CLP criteria, the 4thVersion 2013.
Conclusion on classification
As outlined in the UN GHS (2009) and the Guidance on the application of the CLP criteria (ECHA, 2012), the classification of complex metal compounds should be determined based on the specific ecotoxicity data in considering the solubility properties of each individual constituent of this complex substance. Since the test substance is considered as readily soluble, a transformation/dissolution test is not required. Therefore the classification for the aquatic toxicity can be assigned based on the ecotoxicity data tested specifically for the substance as such.
Classification of the test item on available experimental data (self classification) and on the fact that Nickel oxide as one component of the test substance is listed in Annex VI, Table 3.1, CLP and Annex I, ATP31, DSD:
CLP:
Self classification:
The substance is considered not to be rapidly degradable.
The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish and invertebrates, either for the most sensitive species algae. Therefore, the substance does not meet the criteria for classification and labelling as acute aquatic hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).
Valid chronic toxicity data are available for algae, with a NOERL of 0.36 mg/L. Therefore the substance needs to be classified and labelled as long-term aquatic hazard Chronic Cat. 2 according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).
M-factor for chronic aquatic toxicity: not need to be assigned
Classification according to Nickel oxide listed in Annex VI, Table 3.1:
The harmonized classification in Annex VI to CLP associated with the presence of nickel oxide in the substance resulted in Aquatic Chronic Cat. 4. This does not need to be considered, as Aquatic Chronic Cat. 2 is already identified for the substance as such.
DSD:
Self classification:
The substance is not considered to be biodegradable. The lowest acute aquatic toxicity L(E)C50 value is > 1 to < 10 mg/L. Furthermore a NOERL for algae is available < 1 mg/L. The substance, therefore, needs to be classified and labelled as environmental hazard, R51/53 according to the Directive 67/548/EEC.
Classification according to Nickel oxide listed in Annex I, ATP31:
Classification according to Directive 1999/45/EEC (DPD) resulted in R53. This classification does not need to be considered, as R51/53 is already identified for the substance as such.
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).
