"Slags, precious metal refining" is a complex metal containing UVCB substance with wide concentration ranges for each constituent. Each individual constituent of " Slags, precious metal refining " may contribute (as 'relevant' component) to the UVCB toxicity. With knowledge of the composition, mineralogical information and knowledge of corresponding toxicity of the various chemical species, the respective mixture rules in accordance with Regulation (EC) 1272/2008 are used to calculate the C&L of " Slags, precious metal refining ".
MeClas was used to automatically calculate the classification of the UVCB substance. The calculation tool is based on a database containing the human and environmental hazard information for each component relevant for classification. The information on the representative mineralogical composition (distribution pattern for each constituent of the UVCB substance) is incorporated into MeClas as well.
From the derived hazard category (output of MeClas) the corresponding human health (HH) toxicity value was deduced.
The following data were used as input of MeClas:
1. Classification from individual components according to Annex VI of the CLP regulation (Regulation (EC) 1272/2008) and the 2nd ATP to this regulation, unless additional information on self-classification was used.
2. Percentage of the components in the UVCB: individual total element concentrations (percentages based on total substance amount) were recalculated into percentage of the classified chemical species (i.e. substance), taking into account the distribution pattern of the respective element in its present various mineral forms if such information was available.
The described MeClas-based-calculation provides a conservative estimate of toxicological effects of "Slags, precious metal refining", derived on basis of the mixture C&L rules set forth in Regulation (EC) 1272/2008 using mineralogical information from a representative/worst case sample.
