| Abstract |
The higher incidence of silicosis in fettlers from Czech steel foundries than in those from grey-iron foundries led the author to analyse the composition of the sands used and of the airborne dust at the workplace, and to compare the results obtained to the biological action of this dust in animal experiments. The cristobalite content of sand adhering to steel castings was 14.5%; the sand on grey-iron castings contained no critobalite. Airborne dust in steel foundries contained 10% alpha-quartz and 4.3% cristobalite; airborne dust from grey-iron foundries contained 21% alpha-quartz but no cristobalite. Steel foundry airborne dust produced silicotic nodules but grey-iron foundry dust did not. Cristobalite therefore seems to be an aetiological factor in foundry fettlers' silicosis. |
