bullion, Platinum Group metals rich refining is a complex metal
containing UVCB substance with wide concentration ranges for each
constituent. Each individual constituent of Lead bullion, Platinum Group
metals rich 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 Lead bullion,
Platinum Group metals rich refining.
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.
derived hazard category (output of MeClas) the corresponding human
health (HH) toxicity value was deduced.
following data were used as input of MeClas:
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
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.
described MeClas-based-calculation provides a conservative estimate of
toxicological effects of "Lead bullion, Platinum Group metals rich",
derived on basis of the mixture C&L rules set forth in Regulation (EC)
1272/2008 using mineralogical information from a representative/worst
specific information for the UVCB substance "Lead
bullion, Platinum Group metals rich" is
not available for the endpoint "Sensitisation". 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 skin sensitiser that trigger
classification of the mixture and respective rules of Regulation (EC)
1272/2006 section 184.108.40.206 “Classification of mixtures when data
are available for all components or only for some components of the
mixture” with the MeClas tool. This approach has been presented and
discussed with ECHA in several meetings.
For "Lead bullion, Platinum Group
metals rich" one C&L entry (i.e., Skin Sens. 1) for “Skin Sensitisation”
"Lead bullion, Platinum Group
metals rich" possesses
a skin sensitisation potential in accordance with Regulation (EC)
1272/2008 and requires
classification as skin sensitiser Skin Sens.
1 (H317) in
accordance with Regulation (EC) 1272/2008.
"Lead bullion, Platinum Group metals rich" does
not contain any constituent ≥ 0.1 % (w/w) that is itself classified for
respiratory sensitisation. Hence, the substance does not meet the
classification criteria for respiratory sensitisation in accordance with
Regulation (EC) 1272/2008.
