The ERG is leading a major project to better understand the health problems caused by air pollution and noise from traffic in London.
The project is funded by a £2million grant under the cross-Research Council Environmental Exposure and Health Initiative
with funds from the Natural Environment Research Council
, the Medical Research Council
and the Department of Health
King's are leading a consortium of over 20 investigators from Imperial College London, St George's,
University of London and The London School of Hygiene and Tropical Medicine. The project will run from 2011 to 2014 inclusive.

The project has several interrelated parts:
Work Package 1
The first part of the study is concerned with detailed measurements of air pollutants with chemical
analyses of particles to investigate their toxicity and sources.
This will include linking these data
to daily data from registries of deaths and hospital admissions to study which mixtures and sources of
particles are most likely to have adverse effects. It will be one of the first studies to link
epidemiological analyses to laboratory analyses in this way.
Work Package 2
The second part is the development of models
of exposure to air pollution which draw on information about concentrations, emissions and time-activity.
This includes a novel approach using anonymous Oyster card information and/or GPS on mobile phones, which
will then be analysed alongside pollution measurements to create a mathematical model.
This model will provide a way of investigating the effects of various policy scenarios
on actual exposure of population sub-groups. It will provide a guide to enable people to
adapt their journeys if desired and where possible to reduce their exposure to harmful vehicle emissions.
Lastly, it will improve the estimation of exposure for health studies which
generally rely only on concentrations at the postcode or address level.
Work Package 3
The third main component is to investigate the association between long term exposure
to traffic pollution, indicated by concentrations at address or postcode, and a range of
potential health effects from cradle to the grave.
These include effects on children’s
health and risk factors for future cardiovascular disease, adverse reproductive outcomes
(low birthweight and pre-term delivery), primary care data on disease and consultations,
the incidence of heart attacks, hospital admissions and mortality.
This will be the first study to bring all these outcomes together in a coordinated way and with the explicit aim of
developing exposure- response relationships for use in health impact assessments.
Policy refinement arising from this project
Vulnerability conclusions arising from this project
"This is an exciting new project which will tell us much more about how pollution affects the
health of people in the city. We already know traffic pollution can have adverse effects on the
health of some people living and working in London, but this project
will allow us to understand better the risks to individuals as they go about their everyday lives."
