Additional information

The pigment hematite chromium green black is environmentally and biologically inert due to the characteristics of the synthetic process (calcination at high temperatures, approximately 1000°C), rendering the substance to be of a unique, stable crystalline structure in which all atoms are tightly bound and not prone to dissolution in environmental and physiological media. Based on the resulting physico-chemical properties, especially the high insolubility of the pigment under environmental conditions, demonstrated by (Pardo Martinez, 2010) via transformation/dissolution testing (7 and 28 days), the substance can be expected to not have a potential to cross or adsorb to biological membranes. Therefore, no reversible or irreversible adverse toxicological effects on aquatic or terrestrial life-forms are expected, and a PNEC derivation is scientifically not justifiable.

Conclusion on classification

Based on the high insolubility of the pigment under environmental conditions, demonstrated by (Pardo Martinez, 2010) via transformation/dissolution testing (7 and 28 days), no reversible or irreversible adverse toxicological effects on aquatic or terrestrial organisms are expected. Hence no environmental classification is required.
