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.
Endpoint summary
Administrative data
Description of key information
The test substance, Dust, steelmaking, was tested for subacute toxicity using the EU method B.7. Repeated Dose (28-days) Toxicity (Oral); the test was performed according to GLP rules.
Key value for chemical safety assessment
Repeated dose toxicity: via oral route - systemic effects
Endpoint conclusion
- Dose descriptor:
- NOAEL
- 300 mg/kg bw/day
- Study duration:
- subacute
- Species:
- rat
Additional information
No Observed Adverse Effect Level:
NOAEL = 300 mg/kg/day (rat males/females, oral, 28 d) (established on the basis of haematology and biochemistry examination)
Repeated dose toxicity: via oral route - systemic effects (target organ) cardiovascular / hematological: other
Justification for classification or non-classification
According to results of test of Repeated dose (28 days) Toxicity (Oral) the test item do not fulfil criteria and does not need to be classified as specific target organ toxicants following repeated exposure.
