Évaluation de l’exposition en zones urbaines à la pollution atmosphérique : méthodes existantes et application aux PM10 en France métropolitaine

Abstract: L'évaluation des impacts sanitaires liés à la pollution atmosphérique requiert la connaissance quantifiée de l'exposition des populations. Cette exposition peut être mesurée ou estimée, individuellement ou collectivement. Au plan collectif, plusieurs approches permettent d'estimer la répartition spatiale des expositions : 1) l'approche dite « déterministe » part de l'inventaire des sources et de leurs flux d'émission et calcule les concentrations atmosphériques résultantes, 2) l'approche dite « probabiliste » … Show more

“…High correlation coefficients (r>0.73) between interpolated and measured values, together with low mean quadratic errors, confirm the validity of the multivariate geostatistical models (Nicolas Jeannée, personal communication). The geostatistical interpolation techniques (kriging-like techniques)19 have been commonly applied for several years to estimate air pollution at unsampled locations 20 21. The estimation process, based on measured concentrations, takes into account the spatial structure of each pollutant; the better the spatial continuity of the pollutant, the better the confidence one can have in the estimate.…”

“…Generally, measurement sites can be of 3 types: (1) Local stations, generally used to control classified establishments, are located in proximity of the polluted source to be monitored and therefore under the direct influence of this pollution source; (2) Urban background stations, used to monitor urban pollution, are located in an urban environment but under the indirect influence of pollution sources, and (3) Background stations, are located in a peri-urban environment. It is important to note that local stations are therefore not included in this study as they only provide very local information (Jeannée et al, 2006). In our study, urban background stations are mainly influenced by major west-African urban sources, i.e., the domestic fires, the waste burning and the road traffic (from combustion or non-combustion).…”

“…To validate the extrapolation of the modeled NO 2 concentrations (2005)(2006)(2007) to the four preceding years (for n¼ 2061 women with pregnancies between 2002 and 2004), we calculated a Pearson correlation coefficient between the NO 2 concentrations at their homes according to the 100-m grid over the [2005][2006][2007] period and the annual NO 2 concentrations from two other datasets: the nationwide French NO 2 concentrations at a 4-km grid, established in 2000 (Jeannée et al, 2006), and Europe-wide NO 2 concentrations at a 1-km grid established in 2001 (European APMoSPHERE project) (Beelen et al, 2009 To seasonalize these spatial exposure estimates we included a temporal component depending on the conception and delivery dates (Slama et al, 2007;Lepeule et al, 2010). We obtained hourly air pollution data from Air Breizh, the air quality monitoring station (AQMS) network from Brittany.…”
