Principles of method if other than guideline:
The C&L considering reproduction toxicity (effects on male or female fertility) of "Flue dust, precious metal refining" was determined by using the “Classification criteria for mixtures” of Regulation (EC) 1272/2006 section 3.7.3.1 “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”).

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.

Conclusions:
"Flue dust, precious metal refining" (Flue dust 1 - Flue dust 3) contains lead and lead compounds ≥ 0.3 % that possess reproduction toxicity potential (i.e., suspected of damaging fertility). Hence, "Flue dust, precious metal refining" must be classified as reproductive toxicant Repr. 1A (H360Df).
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.

Effect on fertility: via oral route

Effect on fertility: via dermal route
Endpoint conclusion:
no adverse effect observed
Additional information

Substance specific information for the UVCB substance "Flue dust, precious metal refining" is not available for the endpoint "Toxicity to Reproduction" with respect to effects on fertility. 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 it was agreed within the consortium to use the classification information from the individual constituents and calculate the resulting classification by using the “Generic concentration limits of ingredients of a mixture classified as reproduction toxicants or for effects on or via lactation that trigger classification of the mixture"and respective rules of Regulation (EC) 1272/2006 section 3.7.3.1 “Classification of mixtures when data are available for all ingredients or only for some ingredients of the mixture” with the MeClas tool.

In total three different grades of "Flue dust, precious metal refining" (Flue dust 1 – Flue dust 3) were identified by the consortium that could be grouped according to their calculated C&L resulting from the individual composition. Thus, for "Flue dust, precious metal refining" only one C&L entry for reproductive toxicity (classification forRepr. 1A) was calculated.


Short description of key information:
No information on animal testing of "Flue dust, precious metal refining" is available. However, "Flue dust, precious metal refining" contains amongst others lead and lead compounds ≥ 0.3 % that may cause reproduction toxicity (i.e., suspected of damaging fertility). Hence, "Flue dust, precious metal refining" must be classified as reproductive toxicant.

Effects on developmental toxicity

Description of key information
No information on animal testing of Flue dust, precious metal refining is available. However,Flue dust, precious metal refining contains amongst others lead and lead compounds ≥ 0.3 % that may cause reproduction toxicity (i.e., suspected of damaging fertility). Hence, Flue dust, precious metal refining must be classified as reproductive/developmental toxicant.
Additional information

Substance specific information for the UVCB substance Flue dust, precious metal refining is not available for the endpoint "Toxicity to Reproduction" with respect to effects on developmental toxicity. 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.

Justification for classification or non-classification

Reproductive toxicity classification of UVCB substances is based on the presence of a constituent ≥ 0.3 % classified for reproductive toxicity. Flue dust, precious metal refining (Flue dust 1 - Flue dust 3) contains amongst others lead and lead compounds ≥ 0.3%. Hence, Flue dust, precious metal refining is considered to induce reproductive toxicity, and should be classified as Repr. 1A (H360Df: may damage the unborn child, suspected of damaging fertility) in accordance with Regulation (EC) 1272/2008. There is not any evidence of effects on or via lactation for any constituents of Flue dust, precious metal refining at a concentration≥ 0.3%.
