- particle size distribution and relevance of “respirable fraction”
- classification via mixture toxicity rules

Key value for chemical safety assessment

Additional information

The UVCB substance is a complex metal containing substance. Each individual (metal) constituent of this UVCB substance can release soluble ions that can contribute (as ‘relevant’ component) to the mixture toxicity. With knowledge of the elemental composition (IUCLID section 1.4 & 1.2) and mineralogical information on the Grade representative sample (IUCLID Section 4.23), the mixture toxicity rules (EU CLP Guidance Annex I: 3.9.3.4, and cut-off) was used to calculate the Classification of the UVCB substance.  

Chemistry and mineralogy of the material (see IUCLID section 4.23 chemical and mineralogical characterization) were taken into account.

Justification for classification or non-classification

Specific Target Organ Toxicity (repeated): not classified

The classification derived is applicable to Grade 1 Copper matte

Specific Target Organ Toxicity (repeated): Category 2 H373 (oral)

The classification derived is applicable to Grade 2 Copper matte

See end-records and discussion above for detailed justifications

The tested sample was representative for typical across industry (each Grade), defined within the concentration ranges outlined under IUCLID section 1.2
