Study on effect of airborne dust on London Underground staff

A new study led by Imperial College London has found that London Underground staff working in parts of the network where particulate matter (PM2.5) levels are highest tend to take more sick leave than colleagues in less polluted areas. The study, published in the Environment International journal, did not find enough evidence to prove a direct link between exposure to airborne dust on the Tube and higher levels of sickness absence but said more research is needed.
