GHS

General Information

Implementation:

EU

Remarks:

The hazard assessment of the UVCB as such is driven by the hazard of the individual UVCB chemical elements and related speciation. For the purpose of hazard assessment in the absence of data, the UVCB is treated as a complex metal containing substance with a number of discrete constituting compounds (i.e. chemical element with discrete species). The hazard classifications of each constituting compound are then factored into a combined classification of the UVCB as a whole.
Nickel matte has a harmonized classification listed in Annex VI of the CLP. In order to address the registration data requirements (Annex VII to Annex X) and confirm this classification, a read-across approach has been applied to estimate the effects for relevant toxicological and eco-toxicological endpoints of the nickel matte based on read-across from its classified constituents. The principles of the method are: (1) Calculation of the classification of the UVCB substance applying the rules for mixtures as set up in EU CLP Section 4.1.4. (2) Derivation of the hazardous concentration of the UVCB corresponding to the calculated classification category using the adequate EU CLP Guidance Annex I table. This approach provides conservative hazard estimates and furthermore considers the variability in elemental (chemical) composition of the UVCB.
The chemistry and mineralogical data demonstrate that for all tested mattes, although the mineralogical composition of the UVCB may vary slightly, a common mineralogical pattern exists (eg mainly sulphides). A reasonable worst case (RWC) speciation pattern for each constituting element was therefore derived on basis of observed mineralogies/speciation and reasonable worst-case considerations for non-observed ones.
Due to the variability in mineralogical composition, three main groups consisting of seven generic (i.e. across industry) compositions with distinct elemental (chemical) constituents and linked classifications were derived. For each composition, reasonable worst case assumptions were made with regards to the elemental constituents and speciation: (1) maximum of the company elemental concentrations reported; (2) the actual speciation reported were used if available. In absence of speciation measurements or if different species co-exist (eg intermetallic and metal-sulfides); the species with the worst case classification was used.
