Additional information

Substance specific information for the UVCB substance "Matte leaching residue" is not available for the endpoint “toxicokinetics”. However, there is no specific requirement to generate toxicokinetic data under Regulation (EC) 1907/2006 (REACH). Annex I, Section 1.0.2 of REACH regulation states that “the human health hazard assessment shall consider the toxicokinetic profile (i.e. absorption, metabolism, distribution and elimination) of the substance” and REACH regulation announces in Annex VIII, Section 8.8.1 that one should perform “assessment of the toxicokinetic behaviour of the substance to the extent that can be derived from the relevant available information”.

Nevertheless, for "Matte leaching residue", the human health (HH) hazard assessment is driven by the hazard assessment of the individual UVCB constituents which are (i) classified for HH and (ii) with a content ≥ 0.1 %. For most of the relevant constituents, toxicokinetic data are fully assessed and included in each individual REACH registration file but have not been included in the registration file of "Matte leaaching residue" (see strategy of registration for UVCB substances – Precious Metals Refinables). Relevant hazard and risk assessment information for "Matte leaching residue" can be found in IUCLID Section 7 “Toxicological information_Matte leaching residue 1 -3”.
