Pneumoconiosis in chromite miners in South Africa.

Radiographic outcomes among South African coal miners.

OBJECTIVES This study, the first to document the prevalence of pneumoconiosis among a living South African coal mining cohort, describes dose-response relationships between coal workers' pneumoconiosis and respirable dust exposure, and relationships between pneumoconiosis and both lung function deterioration and respiratory symptoms. METHODS A total of 684 current miners and 188 ex-miners fro...

Mortality of middle aged white South African gold miners.

A cohort of 3971 white miners in South Africa, born between 1 January 1916 and 31 December 1930 who were alive on 1 January 1970 and currently working in the East Rand-Central Rand-West Rand mining areas, was followed up for nine years, when the 3426 survivors were aged from 48 to 62. Fifteen (0.4%) had been lost to view and 530 had died (13.4% of the 3956 whose vital status was determined). Ba...

Death rates of miners and ex-miners with and without coalworkers' pneumoconiosis in south Wales. 1955.

Blood Groups of Miners with Coal-workers' Pneumoconiosis and Bronchitis.

An unexpected finding in a survey of a random sample of men from the Rhondda Fach valley in South Wales suggested an association between blood group A and coal-workers' pneumoconiosis. A further and larger sample of 1,250 miners and ex-miners from the same area, covering the same age range of 35 to 64 years, was chosen at random from the population in order to verify this finding. Each man was ...
