Trends in lung cancer in London in relation to exposure to diesel fumes
Authors:R.E. Waller
Abstract:Mortality from lung cancer among males in England and Wales is now beginning to decline, and the urban excess that has persisted for many years is also becoming smaller. There is nothing in these national trends to suggest that pollution from diesel vehicles, which has been increasing in recent decades, would be involved. Some preliminary results are presented from a long-term study of the incidence of lung cancer among London Transport staff, including men who work in bus garages where there are high concentrations of smoke from diesel buses. Over the 25 year period from 1950–1974 the numbers of cases reported in each of the several job categories have been below those expected on the basis of Greater London rates. The absence of data on smoking habits makes it difficult to determine whether the small differences in rates between job categories are of any importance, but the standardised mortality ratios are all well within the range of those found in national studies of lung cancer mortality and smoking in relation to occupation.
