Description of key information
With regard to the black pigment, the hematite constituent is neither bioaccessible nor toxic.
Quartz and feldspar minerals are a major constituent of the earth´s crust, and therefore not necessary for the assessment.
Hence only data for lead has been used for the assessment of the black pigment. The lead in the black pigment is predominately lanarkite (insoluble), while data assessed for bioaccumulation/bioconcentration stems from soluble lead salts. Thus the assessment is well in accordance with the precautionary principle.
The following bioaccumulation/bioconcentration factors have been derived for Pb:
- Aquatic compartment
Bioaccumulation/bioconcentration factors in freshwater: 1,553 L/kg (wet weight)
- Soil compartment
Bioaccumulation/bioconcentration factors in soil: 0.39 kg/kg (dry weight)
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
