Abstract
Working on the relationship between respiratory health and atmospheric
pollution in French cities led us to adopt a perspective that considers the risk for
a single city of showing high levels of respiratory health problems. The risk level
in a city is dependent on population vulnerability, the city context and pollutant
levels. This presentation focuses on the observation of the unequal pollution
hazards in French cities on a macro-scale. The study field covers 34 French cities
of more than 100,000 inhabitants. The aim is to build different synthetic
indicators of atmospheric pollution that consider the temporal and spatial
diversity within a city, and to compare the different results. The focus is on the
results for nitrogen dioxide (NO2) over the 2007 and 2008 winter season. The
paper presents the database and methodology used. The findings show that the
spatial structure of air pollution between the cities remains globally the same
whatever the indicator chosen. However, the results also show significant
changes in the relative position of certain cities. When comparing the more
conventional indicator calculated from mean daily concentrations in urban
monitoring sites with an indicator also taking into account the concentrations
observed in roadside stations, relative changes appear for more than ten cities.
These findings highlight the importance of the criteria used in the choice of the
indicators, and the benefit of using a set of complementary indicators in
epidemiological studies.
