Summary

Following complains of foundry workers about the smoke released by the triggering process in the production of nodular iron, the composition of this smoke and its possible effects on man were investigated.

Non destructive neutron activation analysis showed 34 elements all in concentrations below TLV.

Possible acute effects of this smoke on man were investigated in 10 workers. 8 workers had subjective complains, mainly respiratory discomfort.

Determination of iron in serum and lead in blood of workers before and after exposure to the smoke showed no significant differences. Clinical laboratory investigations and body temperature readings indicate that metal fume fever did not occur.

All subjects showed at different extent decrease of vital capacity shortly after exposure to the smoke. FEV1 showed no consistent changes.

Long term effects of repeated short exposures are unknown.
