baritosis
non-fibrinogenic pneumoconiosis CF
minimal effects on lung and few CF
siderosis caused by
iron
stannosis caused by
tin
Coal Workers’ Pneumoconiosis
caused by the deposition of coal dust within the lung and its associated inflammatory reaction
simple pneumoconiosis
simply reflects the deposition of coal dust in the lung
