AB - The London Underground (LU) provides public transport for millions every day. As concentrations of particulate matter (PM) on the LU network can be several orders of magnitude higher than outside, the exposure of staff and passengers to high concentrations of PM2.5 is a widespread health concern. So far, it has been difficult to quantify the risk of such exposures, as the physicochemical differences between LU and ambient PM mean the established health impacts cannot be extrapolated , toxicological studies have used inconsistent end points, population epidemiological studies have been unable to address the inconsistent exposure levels, and occupation epidemiological studies have been under-powered. This thesis reports the largest occupational study addressing subway PM and has investigated the effects on staff sickness absence (SA) and mortality. While this study found evidence that employees exposed to higher LU PM reported higher rates of SA and had higher mortality risk, the information available from the retrospective cohorts limited the conclusions that could be drawn. Both cohorts lacked information on confounders, especially smoking status, which is known to cause lung cancer and other respiratory diseases. The mortality retrospective cohort lacked job titles with the LU staff, which limited the degree to which exposure could be assigned. Nevertheless, these are the largest cohort studies looking at the health effects of occupational exposure to subway PM and have implications for safer working environments for subway employees.
