Clinical Aspects of Kaolin Pneumoconiosis
China clay or kaolin is mined extensively in east central Georgia and is the major industry in that region. The mining and processing of this mineral is known to lead to the development of a pneumoconiosis (Middleton 1936). Several limited studies have been published, but no well designed large investigation that has included most of the work force has been carried out until recently (Edenfield 1960, Kennedy et al. 1983, Oldham 1983, Altekruse et al. 1984). The present communication summarizes a recent comprehensive study that was carried out and adds some additional information to that which has been published (Morgan et al. 1988).
