Respiratory diseases in iron ore miners and millers.
Workers in iron mines are at risk of developing interstitial lung disease if the dust levels are above the threshold limit value. However, they more commonly develop the usual diseases that affect all workers. Some illnesses, such as chronic bronchitis, bronchial asthma, and the collagen vascular diseases that affect the lung, may be more severe because of the inhalation of dust. The most difficult problem is to differentiate asymptomatic sarcoidosis from pneumoconiosis. The family doctor who also acts as the company doctor must be aware of the potential conflict of interest.
