EC number: 266-007-8 | CAS number: 65996-74-9 The oxidized surface of steel produced during reheating, conditioning, hot rolling, and hot forming operations. This substance is usually removed by process waters used for descaling, roll and material cooling, and other purposes. It is subsequently recovered by gravity separation techniques. Composed primarily of high-purity iron oxides. May contain varying amounts of other oxides, elements, and trace compounds.

Description of key information
Iron is amongst the most common elements in the earth’s crust and can be found in great abundance in both the terrestrial and sediment environments. The relative contributions of anthropogenic iron to the existing natural pools of iron in soils and sediments is therefore not relevant either in terms of added amounts or in terms of toxicity. Based on these exposure considerations additional sediment and/or soil testing is not warranted. More information about exposure based waiving for iron in soil and sediments can be found in attached documents (White paper on exposure based waiving for Fe and Al in soils and sediments final 15-03-2010.pdf - Position Paper_ FINAL 09_03_2010-2.pdf).

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.
