Abstract: In this work we made an analysis for the physicochemical characterization of gasoline sold on the roadsides of the city of N'Djamena. For our first experience on the storage of gasoline in cans exposed to the sun, we noticed the formation of lumps and solid particles at the bottom of the cans. We then sampled a sample by district and subjected it to the analysis conditions. The analyses focused on Density at 15°C; ASTM distillation; Reid vapor pressure, Octane number; Determination of corrosion of copper blades as well as Determination of sulfur content. The results of the analyzed contraband gasolines are out of specifications under normal analysis conditions. Despite the many studies carried out on air pollution by particles, uncertainties remain. It is more or less complex to treat particulate pollution in urban areas, this is in fact due to the modifications resulting from different meteorological factors (wind, precipitation, etc.), topographical (slope, etc.) and urban morphological, which constitute limiting factors in the dispersion of these pollutants, thus, different maps have been studied according to the vulnerability and criticality of the accentuated situation relating to pollution throughout the city of N'Djamena. The results confirm the presence of particles that can affect human health. In addition to the presence of all the elements that we have been able to discover, there is on average the result of the presence of PM10 particles which is: 66.98016239 ug/m3 well above the WHO guideline which recommends 50 μg/m3/day as well as the daily average for PM2.5 which is: 56.83616723 ug/m3 well above the WHO guideline which recommends 25 μg/m3/day. The objective of this article is to clearly present the urgency of air pollution throughout the territory in order to take a binding decision on the current situation based on the proliferation and illicit sale of petroleum products in the city of N'Djamena, particularly gasoline.
