POLLUTIO N ATMO SPHÉRIQUE La popu lation des grandes villes est aujourd'hui exposée à de fréquentes pointes de poilution acido-partic ulaire en hiver, et photo-oxydante en été [9, 13, 15]. Pour éva luer les effets de la pollution atmosphérique sur la santé des popu lations urbaines , une nouve lle approche épidémiologique Epidemiologists who study the relationship between air pollution and health, often compare time-series analysis of daily levels of air pollutants to daily incidence of health

... ffects among the population recorded in the same area . Most of them simply use the arithmetic mean of the daily means of the levels of a pollutant measured at each station of the network ta estimate the daily level of this pollutant over the study area. Nevertheless, fewauthors have been interested in the validation of this use. The purpose of this work was to validate it in the case of black smoke measurements at six stations located in Paris and his close suburbs. The analysis of the statistical distribution of the levels measured at each station, of the time series by the Box-Jenkins approach and, of the correlations between them, allowed us to verity the temporal and geographical homogeneity between data collected at the six stations. This work is a first step for the validation of ecological exposure assessment of an urban population.
