"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.

Conclusions:
"Slags, precious metal refining" - composition profile 1:
Carcinogenicity classification of UVCB substances is based on the presence of a constituent ≥ 0.1 % classified for carcinogenicity Carc. 1A or Carc. 1B and on the presence of a constituent ≥ 1 % classified for carcinogenicity Carc. 2, respectively. "Slags, precious metal refining" - composition profile 1 contains constituents ≥ 0.1 % classified for carcinogenicity Carc. 1A (i.e., nickel oxide, diarsenic trioxide) and Carc. 1B (i.e., cadmium oxide). Furthermore, lead and lead compounds are self-classified as carcinogen Carc. 2. In conclusion, "Slags, precious metal refining" - composition profile 1 is considered to induce cancer and meets classification criteria as carcinogenic substance Carc. 1A and requires labelling with H350 (May cause cancer), in accordance with Regulation (EC) 1272/2008.

"Slags, precious metal refining" - composition profile 2:
Carcinogenicity classification of UVCB substances is based on the presence of a constituent ≥ 0.1 % classified for carcinogenicity Carc. 1A or Carc. 1B and on the presence of a constituent ≥ 1 % classified for carcinogenicity Carc. 2, respectively. “Slags, precious metal refining” -composition profile 2 contains constituents ≥ 0.1 % classified for carcinogenicity Carc. 1A (i.e., nickel and nickel substances). Hence, “Slags, precious metal refining” - composition profile 2 is considered to induce cancer and meets classification criteria as carcinogenic substance Carc. 1A and requires labelling with H350 (May cause cancer), in accordance with Regulation (EC) 1272/2008.
Executive summary:

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.

Additional information

Substance specific information for the UVCB substance "Slags, precious metal refining" is not available for the endpoint "Carcinogenicity". In order to meet the requirements for Annex VII till Annex X of Regulation (EC) 1907/2006, read across information from any constituents being relevant needs to be included. Due to the high number of constituents and variability in C&L of these constituents it was decided to use the classification information from the individual constituents and to calculate the resulting classification by using the “generic concentration limits of ingredients of the mixture classified as carcinogen that trigger classification of the mixture” and respective rules of Regulation (EC) 1272/2006 section 3.6.3.1 “Classification of mixtures when data are available for all ingredients or only for some ingredients of the mixture” with the MeClas tool.This approach has been presented and discussed with ECHA in several meetings.

In total, two different grades of "Slags, precious metal refining" (composition profile 1 – composition profile 2) were identified by the consortium that could be grouped according to their calculated C&L resulting from the specific composition profile. Based on the composition profiles 1 - composition profile 2 for "Slags, precious metal refining" one C&L entry (i.e., Carc. 1A) for carcinogenicity was generated.
