Abstract

Black carbon (BC) is a particular pollutant that absorbs visible light and can intervene in the climatic change with irradiance. The sources of BC emissions are known, such as incomplete combustion of fossil fuels and biomass burning. Our study focuses on two sites Hlm and Yoff in Dakar, Senegal in order to determine the mass absorption coefficient of BC in our polycarbonate nucleopore filters from November 2018 to October 2019 so as to collect PM2.5 and PM2.5-10 we face in our two study sites using MABI instrument. In addition, we investigate the source apportionment of black carbon in PM2.5 fraction. We observe that the mass absorption coefficient of PM2.5 is higher than that of PM2.5-10. The average concentration of BC at Hlm and Yoff were 1.85 ± 0.37 and 2.69 ± 0.54 μg.m−3 respectively, whereas the average concentrations of BCBB were 0.003 ± 0.0007 and 0.08 ± 0.01 μg.m−3, respectively and for BCFF were 1.85 ± 0.37 and 2.61 ± 0.53μg.m−3. The BC from at Yoff has two compounds with 2.97% of Biomass burning and 97, 03% of Fossil fuels in contrast to Hlm site the black carbon was mainly composed of fossil fuels in Dakar, the fossil fuels are mainly source of the black carbon.
