Investigation of Atmospheric Particulate Matter (PM) Mass Concentration Spatial Variability by Means of On-Foot Mobile Measurements in Lille, Northern France

Résumé

Air-quality and pollution levels in urban agglomerations are generally assessed by monitoring stations set up in fixed locations. However, the particulate matter (PM 10, 2.5, 1) mass concentrations at surface level, which are hazardous for environment and human health, can be highly variable in space and time even at a local scale. Thus, there is a need for assessing the spatial distribution of the particulate matter loadings at fine spatial scale. For this, we performed on-road mobile measurements of particle size distributions with a low-cost sensor, Alphasense OPC-N2, in order to estimate the PM 10, 2.5, 1 mass concentration. The measurements were performed in the urban regions of Lille metropolis, in northern France. In this work, we evidence the gradients of  26 Lidia-Marta Amarandi et al. pollution levels between less and more densely populated areas. In our study, we found an increased level of PM x concentrations higher than 40 µg/m 3 near the commercial centers, as well in the city center, whereas regions with less traffic and more rural areas (Villeneuve d'Ascq) are less polluted.
