Description
Summary:	Air pollution has become a major problem in urban areas due to increasing industrialization and urbanization. In this study, the source contribution of particulate material (PM10 and PM2.5) in Barranquilla was quantified. Samples were recolected for periods of 48 hours, at the Universidad de la Costa, with the Partisol 2000-iD equipment and 47 mm Teflon filters. Major and trace elements were quantified using X-ray fluorescence, ionic species with ion chromatography and black Carbon (BC) with the reflectance method. The Positive Matrix Factorization (PMF) model estimated the PM sources contributions. The average concentration of PM10 was 46.6 µg/m3 and 12.0 µg/m3 for PM2.5. The greatest contributions for PM10 were BC, Cl and Ca, and for PM2.5 were BC, S and Cl. Similar sources were obtained for both PM fractions: marine spray (Cl and Na+), resuspended soil (Al, Si, Ti, Fe) and vehicular traffic (BC, Mn and Zn). In addition, PM2.5 was associated with two mixed sources: fuel combustion and fertilizer industry (S, V, P, K+ and SO42-), and a secondary source and civil works (Ca2+ and NO3-). The PM10 was also associated with civil works and resuspended soil (Ti, Mn, Fe) as well with the metallurgical industry (S, Zn and Cu). These results are fundamental to the knowledge about the sources that can have the greatest source contributions and strategies can be implement for the continuous improvement of the city's air quality.
