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.
From dermal toxicity testing with BOS and SMS, it is concluded, that no
components of these UVCB are taken up at relevant concentrations through
the skin. Therefore this absorption of ferrous slag through the skin can
be neglected including toxicokinetics.
Inhalative testing according to TRGS 430 (in combination with OECD 403)
was done with GGBS. Neither the acute test nor in the post exposure
period showed a toxic effect. Therefore no toxicokinetics can be
