EC number: 294-409-3
CAS number: 91722-09-7
Substance formed during processing of liquid steel or during production of iron castings. Consists primarily of fused silicates and trace elements as oxides as well as trace of alloying elements.
ABS: Vibrio fischeri Microtox: 30 min-EC50 > 80 g/L
In two acute toxicity tests according to the Microtox procedure,
undiluted, neutralized leachate of ABS (DIN 38414 -4/DEV-S4, L/S
10/1) had no effect on the bioluminescence of the marine
proteobacterium, Vibrio fischeri. After 30 min of incubation there
was no decrease in biofluorescence, and the EC50 is larger than 80
g/L (nominal), the highest concentration tested (BfG 2008).
Leachate of air-cooled blast furnace slag (ABS, subtype toploader
kiln slag) is not inhibitory on the bioluminecence of the marine
bacterium, Vibrio fischeri, in a test according to ISO 11348. The
30 min-IC0 is >= 100 mg/L (nominal, highest concentration tested),
the IC50 is > 100 mg/L (Hygiene-Institut des Ruhrgebiets 2008).
This value is disregarded for assessment because the insolubility
of the slag is a desired property of the slag for its use in
construction. The low solubility was the reason why the
experiments were ordered to be made with extrem low concentrations
instead of concentrations relevant for the environment.
