Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 266-005-7 | CAS number: 65996-72-7 The dust generated during the charging, operation, and tapping of a steelmaking furnace and from steel conditioning, including that which is recovered through the use of pollution abatement equipment. Composed primarily of iron oxides. May contain varying amounts of other metallic oxides and trace compounds.

Description of key information
The test was performed according to EU Method C.3 (Algal Inhibition Test).
The study was performed without the analytical determination of the test substance concentrations. Because the test substance is multi-component poorly soluble substance the water-accommodated fractions (WAFs) were prepared for preliminary and full test.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
As the test substance was tested by using the water-accommodated fractions (WAFs) and nominal concentrations (loading rates) were used, EL (resp. NOELR) parameters were used instead of EC (resp. NOEC) values.
EL50 (72 h) > 100 mg/l.
NOELR (72 h) = 100 mg/l.
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.
