摘要

The lack of data on air quality monitoring and neglected and overlooked pollutant emissions in the transportation and industrial sectors are motives for the government of Senegal to set up, in 2009, an air quality management center, the CGQA</span><span style="font-family:""> </span><span style="font-family:""><span style="font-family:Verdana;">(Centre de Gestion de la Qualité de l’Air). Air quality monitoring at CGQA deals with mainly six pollutants: carbon monoxide (CO), nitrogen oxides (NO</span>_{<span style="font-family:Verdana;">x</span>}<span style="font-family:Verdana;">) (with nitrogen dioxide (NO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">) and nitrogen monoxide </span><span><span style="font-family:Verdana;">(NO)), sulfur dioxide (SO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">), ground-level ozone (O</span>_{<span style="font-family:Verdana;">3</span>}<span style="font-family:Verdana;">), Benzene-Toluene-Xylenes</span></span><span style="font-family:Verdana;"> (BTX), and particulate matters (PM) with diameters less than 10 μm (PM</span>_{<span style="font-family:Verdana;">10</span>}<span style="font-family:Verdana;">) and 2.5 μm (PM</span>_{<span style="font-family:Verdana;">2.5</span>}<span style="font-family:Verdana;">). The concentration levels of gaseous pollutants (CO, O</span>_{<span style="font-family:Verdana;">3</span>}<span style="font-family:Verdana;">, NO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> and SO</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">) in the city generally remain below the limit value set by the WHO (World Health Organization). However, particulate matters (PM</span>_{<span style="font-family:Verdana;">10</span>}<span style="font-family:Verdana;"> and PM</span>_{<span style="font-family:Verdana;">2.5</span>}<span
