oflung cancer associated with haematite mining. During the 20-year period there were 42 deaths attributed to lung cancer among iron mine employees resident in the study area: 36 ofthese occurred in miners working underground, which was significantly greater than that expected from local non-mining (20-6 deaths) or national (21-5 deaths) experience.
Cancer of the lung in iron ore (haematite) miners. The mortality of Cumberland iron-ore miners has been studied by examining the death certificates of 5 811 men resident in two local authority areas (Ennerdale R.D. and Whitehaven M.B.) who died between 1948 and 1967.
A parallel analysis of mortality among coal miners showed a deficit of deaths from lung cancer in line with other studies. The patterns of other respiratory mortality in the two local mining groups were also in line with previous experience, and confirmed the existence of a substantial silicotic hazard associated with haematite mining in ...
A dust survey was carried out in a group of eight haematite mines, prior to the use of water for dust control, and was repeated later, when practically all dust-producing sites were subjected to wet treatment. No changes in ventilation or other procedure were made in the intervening period. Settled dust samples had been shown to contain from 9 per cent. to 16 per cent. of free silica, and the ...
