Abstract :
[en] This study addresses the issue of air quality in the city of Kinshasa, capital of the Democratic Republic of Congo (DRC). It is based on the study of the spatial distribution of trace species such as NO2 and CO in this city. The two species targeted in this study are major contributors to air quality degradation as promulgated by the World Health Organization. Real-time monitoring of the chemical concentration of these species is strongly recommended. Raw data were collected over a three-day period, using mobile measurements from a car. The chemical concentration of NO2 was sampled using DOAS (Differential Optical Absorption Spectroscopy) and its spatial distribution was achieved using GPS surveys. The NO2 concentration measurements are valid over a distance covering a radius of 1 km from each sampling point. The result of this study showed that the communes of Limete and Gombe (heavy goods vehicle section) are much more affected by NO2 pollution, followed by the large crossroads with intense commercial activity zones such as in the commune of Mont ngafula (Matadi mayo market) or at the Ngaba traffic circle. The concentration of CO was taken thanks to a LOW Cost sensor, giving in situ measurements. As the instrument used was of low accuracy, quantitative analysis of CO was not performed. Nevertheless, the CO signal was detected in almost all the communes of the city of Kinshasa.
