Additional information

For classification purposes, the classification of the UVCB is based on the hazard of the constituents. This has been determined following CLP mixture toxicity rules using the MeClas tool.

For risk assessment purposes, the assessment covers the risks posed to all relevant environmental compartments by releases of selected environmental driving constituents during the production and use of the refinable substances. Exposure assessment has been undertaken separately for each of the driving constituents. These are arsenic, cadmium, chromium, copper, lead, nickel, silver and zinc. The refinable substances have variable composition and may not contain all of the environmentally hazardous constituents so the generic exposure assessment for each refinable substance only considers the relevant constituents.

Conclusion on classification

The environmental classification for this substance has been derived using the MeCLAS tool. The classifications for Lead bullion, PGM rich, are grouped classifications based on the composition profiles. This approach has been used for lead bullion, precious metal rich, as it consists of a small and relatively uniform (yet still sufficiently variable to be considered a UVCB) group, where a number of composition profiles are expected to be manufactured and/or imported.


·        For the speciation used for classification, please refer to the table in CSR Section 3.0.3.

·        Classification drivers are (worst case) assumptions and do not necessarily represent real species/mineralogical composition.

Lead bullion, PGM rich

The MeCLAS tool has been used to derive the classification for lead bullion, precious metal rich, on the basis of its composition, showing that it would be classified for the environment under CLP as Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410).
