Materials and methods

Principles of method if other than guideline:
The C&L for eye irritation/corrosion of "Flue dust, precious metal refining" (Flue dust 1) was determined by using the “theory of additivity” of Regulation (EC) 1272/2006 section 3.2.3.3. “Classification of mixtures when data are available for all components or only for some components of the mixture”. For detailed information for classification strategy of UVCBs please refer to IUCLID section 13 (attachment “PMC Classification method”).

Results and discussion

Any other information on results incl. tables

Flue dust, precious metal refining is a complex metal containing UVCB substance with wide concentration ranges for each constituent. Each individual constituent of Flue dust, 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 Flue dust, 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.

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The UVCB substance "Flue dust, precious metal refining" ( Flue dust 1) does not possess an eye irritation/corrosion potential in accordance with Guidance on the application of the CLP criteria Version 4.0 - November 2013 (theory of additivity was applied).
Hence, "Flue dust, precious metal refining" does not require classification as eye irritant according to Regulation (EC) 1272/2008.
Executive summary:

The described MeClas-based-calculation provides a conservative estimate of toxicological effects of "Flue dust, 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.
