To test the dermal toxicity of slags,
steelmaking, converter (BOS) and crushed stone from a quarry in the
vicinity of Serra, Brasilia, tests were performed following OECD
guideline 402 in Wistar rats. Fine-ground BOS and crushed stone were
dosed, in their original form, at 4 g/kg bw (body weight) under
semi-occlusive dressing for 24 h. After dosing, the patches were removed
and the animals were observed for a post exposure period of 14 days. The
LD50 was > 4000 mg/kg bw for each test material.
Slags, steelmaking, converter (BOS) and
natural stone from a quarry in Serra, Brasilia, are not toxic via the
dermal route, and do not need to be
classified as dermal toxicants. No signal word and no hazard statement
