Conclusion on classification
- Fishfreshwater: 14.4 mg Sb/L (P.promelas, Brooke et al (1986))
- Fishmarine: 6.9 mg Sb/L (P.major, Takayanagi (2001))
- Invertebrates: 12.1 mg Sb/L (D.magna, Kimball (1978))
- Algae: >36.6 mg Sb/L (P.subcapitata, Heijerick & Vangheluwe (2004))
- Fishfreshwater: 1.13 mg Sb/L (P.promelas, Kimball (1978))
- Invertebrates: 1.74 mg Sb/L (D.magna, Heijerick & Vangheluwe (2003))
- Algae: 2.11 mg Sb/L (P.subcapitata, Heijerick & Vangheluwe (2004))
The effect assessment has found a 72 h LC50of 1.77 โ 1.95 mg Sb/L performed on the invertebrates Chlorohydra viridissma and Hydra oligactis (TAI, 1990) as the lowest valid value for acute toxicity. Although the hydra data is suitable for use in the risk assessment, the guidance on the classification and labelling of substances is clear that the hazard classification should be based on data for standard test species that are generated according to accepted test protocols (e.g. OECD testing protocols). Such data take precedence over information that is generated with non-standard test species. The principle of classification is to indicate the relative toxicities of different substances and the use of data from standard test species would give a more consistent comparison against other substances which have classifications based on standard tests.
For the purposes of classification, data for daphnids (DSD) or crustacea (CLP regulations) is preferred to fulfil the invertebrate endpoint. Therefore, the data for Hydra will not be used for the purposes of classification.
The lowest acute values for the different taxonomic groups are:ยท
The marine fish P.major is not a standard test species, and classification is typically based on freshwater data when available.
The acute reference value for assessing the acute environmental classification of antimony (and antimony compounds) is therefore 12.1 mg Sb/L (= lowest acute value for the freshwater compartment). This value is higher than the Acute Cat.1 maximum threshold of 1 mg/L. It can thus be concluded that Sb and Sb compounds are not classified for the acute environmental endpoint.
Expressed as KSb(OH)6 (molecular weight conversion), this value increases to 26.1 mg/L.
The lowest chronic values for the different taxonomic groups are:
The chronic reference value for assessing the acute environmental classification of antimony (and antimony compounds) is therefore 1.13 mg Sb/L. (= lowest chronic value for the freshwater compartment). This value is higher than the Chronic Cat.1 maximum threshold of 1 mg/L. It can thus be concluded that Sb and Sb compounds are not classified for the chronic environmental endpoint.
Expressed as KSb(OH)6 (molecular weight conversion), this value increases to 2.44 mg/L.
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).
