Abstract |
Chest radiographs were taken from 547 men who had worked at a colliery during the 1970s. Classifications of these films under the International Labour Organisation (ILO) 1980 scheme were related to existing data on individual men's exposures to respirable dust and quartz. 203 men (38%) showed progression of at least one profusion category on the 12-point scale, from the various 1970s surveys to the follow up in 1990-1. 158 men (29%) had a profusion of at least 1/0, and 47 (8.6%) of at least 2/1 at the follow up survey. Large opacities were recorded by at least two readers for 14 (2.6%) of the men. Profusion of small opacities was strongly related to exposures experienced in the 1970s, and more strongly for quartz than for the non-quartz fraction of the dust. Estimates of risk are presented over the range of quartz exposures experienced. The quartz exposures experienced by some men at this colliery have caused considerable progression of radiographic abnormalities since exposure ended. |
