EC number: 266-002-0 | CAS number: 65996-69-2 The fused substance formed by the action of a flux upon the gangue of the iron-bearing materials charged to a blast furnace and upon the oxidized impurities in the iron produced. Depending upon the particular blast furnace operation, the slag is composed primarily of sulfur and oxides of aluminum, calcium, magnesium, and silicon.

Description of key information
ABS: Eisenia fetida OECD 207: 14 d-LC0 = 100 g/kg (highest concentration tested)
ABS: Eisenia fetida ISO 11268-1: 14 d-LC50 = 770 g/kg (highest concentration tested)
Key value for chemical safety assessment
Additional information
In an earthworm acute toxicity test performed according to OECD 207 and GLP, powdered air-cooled blast furnace slag (ABS) did not affect survival or body fresh weight of the earthworm Eisenia fetida during 2 weeks incubation in soil with a maximum concentration of 100 g of the slag per kg of artificial OECD soil (highest concentration tested, NERI 2008).
The effects of slags on earthworms were measured in a 14 d test according to ISO 11268-1 (Effects of Pollutants on Earthworms. 1. Determination of Acute Toxicity Using Artificial Soil Substrate). ABS was not toxic against Eisenia fetida within 14 days. The LC50 was 770 g/kg (highest concentration tested, LECES 1999).
