The particulate air pollution may be natural or anthropogenic, with different shapes and diameters of particles. What allow them to reach the lung and the blood increasing not only respiratory and cardiovascular disease but also the risk of mortality. To eliminate the particulate air pollution in a city such as Meknes, the study of the air pollution distribution in the urban area seems necessary. And as the mapping is the most suitable way for a good spatial representation, we had used geostatistics, which permits the characterization of the spatial variability of any property and, its estimate turns out to be very appropriate to map the phenomenon of dispersion. The maps obtained from of two interpolation methods, the deterministic method: IDW (Inverse distance weighting) and the geostatistical technique: Kriging, show that all districts of the Meknes city suffer from a large dust with different degrees, and that particulate air pollution in Meknes is not limited to the border area of pollution sources but it is characterized by the invasion of other areas (action of prevailing winds).
