Source Apportionment and Assessment of Air Quality Index of PM2.5–10 and PM2.5 in at Two Different Sites in Urban Background Area in Senegal

Identifying the particulate matter (PM) sources is an essential step to assess PM effects on human health and understand PM’s behavior in a specific environment. Information about composition of organic or/and inorganic fraction usually used for source apportionment studies. In this study that took place Dakar, Senegal, identification two fractions was performed by utilizing data elemental carbon content. Four were identified using positive matrix factorization (PMF): Industrial emissions, mineral dust, traffic sea salt/secondary sulfates. To effect air quality index (AQI) estimated. The highest values AQI are approximately 497 488, Yoff Hlm, respectively. spatial location investigated potential contribution function (PSCF). PSCF plots revealed high transported dust from desert regions concentration sampling site. best our knowledge, first published Senegal.
