Atmospheric chemistry and aerosols

Air pollution has become a major concern in Bamako. Road traffic is considered the main cause of this pollution. The overall aim of this study is to assess atmospheric concentrations of carbon dioxide on major roads in Bamako during rush hour. In order to achieve the objectives of this study, the methodology was based on the use of the Testo 535 device to measure atmospheric CO2 concentrations. Some physical parameters related to CO2 concentrations were also measured. Data were recorded and processed using tools (Excel 2019, and the human exposure grid). Research results show that average atmospheric CO2 concentrations in the communes of the city of Bamako range from 347.20 (± 45.03) ppm to 420.80 (± 25.09) ppm, with an overall mean of 382.70 (± 20.27) ppm. The overall mean temperature in the city of Bamako is estimated at 28.97 (± 1.80) °C for a humidity of 65.23 (± 6.88) %. Taking as a reference the average concentration which is equal to 382.70 ppm, each liter of air contains approximately 0.00857 liters (8.57 milliliters) of CO₂. However, variations in CO2 concentrations are influenced by biological, physical and human environmental factors. Health risks of the utmost importance can arise from CO2 air pollution. The results of this study show that Bamako's cars considerably degrade air quality. Mitigation measures must be taken to combat this air pollution
