Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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 materials for reclaim, precious metal with or without support, are grouped classifications based on cluster analysis and expert judgement. This approach has been used for materials for reclaim, precious metal with or without support, as it consists of a large and variable group, where many combinations are possible and hence there was a need to apply cluster analysis to identify conservative classification profiles to arrive at a reasonable number of possible classifications of the individual streams belonging to each UVCB substance.

Notes:

·        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.

There are three different grades of Materials for reclaim, precious metall with or without support, and the environmental classification for each grade is presented below.

Materials for reclaim, precious metal with or without support 1 (low Pb/Ni)

The MeCLAS tool has been used to derive the classification for materials for reclaim, precious metal with or without support 1 (low Pb/Ni), 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).

Materials for reclaim, precious metal with or without support 2 (med Pb/Ni)

The MeCLAS tool has been used to derive the classification for materials for reclaim, precious metal with or without support 2 (med Pb/Ni), 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).

Materials for reclaim, precious metal with or without support 3 (high Pb/Ni)

The MeCLAS tool has been used to derive the classification for materials for reclaim, precious metal with or without support 3 (high Pb/Ni), 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).
