Description of key information
Additional information
FeCr-slag is inorganic mineral material and can be compared to silicate minerals occurring in soil naturally. Potential hazard comes from metals, but there are in highly insoluble because of the FeCr-slag mineralogy. Environmental fate of metals in Ferrochromium slag used in road construction has been studied (Rossi 2005) using MMSOILS 4.0 program. The final conclusions were that metals in FeCr-slag products are highly insoluble and they don’t cause pollution to groundwater. Based on the calculations concentration of Cr or Mo does not exceed any threshold limit set to surface water or domestic water even in long term. Similar results were obtained in tests (SGI 2000) conducted in FeCr-slag containing layers in road constructions: leaching of metals from FeCr-slag and transport is low. In Dandelions growing directly in FeCr-slag containing construction it was observed elevated chromium concentrations in roots, but not in the plant leaves.
Testing to determine biodegradation is not applicable because Ferrochromium slag is inorganic substance. Determination of bioaccumulation in aquatic/sediment compartment is not relevant and not required according to Annex IX, column 2. The substance is highly insoluble to water. Direct and indirect exposure of the aquatic compartment is therefore unlikely.
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.
