The present article describes and comments the data of the particle broadcasts (PM10 and PM2.5) inventoried by the industrial sites for the years 2014 has 2018 and the evolutionary tendencies of the air pollution observed at the level of the industrial stations of the stationary measures in the city of Dakar. Two approaches have been used for the realization of these works: the inventory of the particle broadcasts by the industrial and the campaigns of the measurements, has different periods of the year, by stations of surveillance of the quality of the air of the CGQA situated in the region of Dakar. The obtained results showed a real impact of the industry dismissals on the pollution in the region of Dakar but also of the variation of the particulate pollution to the level of the city. The sector of the energy is the main issuing source of atmospheric particles (PM10) in 2014 with dismissals to height of 58%. Concerning the cartographic representation the region is submitted to strong person concentrations going until 3000 kg/year of broadcasts. The extrapolation of concentration measure in PM10 shows a strong concentration in the West part of the city of Dakar with concentrations middle yearly passing 250 μg/m3. During the whole period of 2015 to 2018, the level of yearly middle concentrations passed the 100 ug/m3 and the maxima concentrations were greater than 550 μg/m3. The evolutionary tendency of concentration of the PM2.5 also follows those of the PM10. These cartographies permitted us to identify the geographical zones spatially or the concentrations are most elevated. However, of the indicators and the levels, relative to the population potentially exposed to overtakings of the yearly value limits are reached also.
