- complex metal containing substance- solubility of metal constituents - classification via mixture toxicity rules
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 1.2 and 1.4) and mineralogical information on a
representative sample (IUCLID Section 4.23), the mixture toxicity
rules (EU CLP Guidance Annex I: 126.96.36.199, and cut-off) was used to
calculate the classification of the UVCB substance.
The Meclas tool was used to automatically calculate the classification
of the intermediate. The tool is based on a database containing the
human and environmental classification for each component relevant for
classification. The information on the representative mineralogical
composition (distribution pattern for each constituent of the UVCB
substance) is furthermore incorporated into the tool, so that the
elemental composition (in % Total element) is automatically converted
into % w/w of compounds that are relevant for applying the mixture rules.
Specific Target Organ Toxicity (repeated): category 1 (Grade 1 and 2)
