Abstract
Abstract: Elemental composition of fine particulate matters coming from the vehicular exhaust emission of jeepneys plying the route of Taft Avenue, Manila, Philippines was identified using SEM/EDX technique. SEM images of each fine particulate matter were also taken for morphological analysis. Elements that were revealed by EDX include Ca, Cl, Co, Cu, Cr, Fe, Mn, Pb, Hg, Ni, P, Na, S, Si, K, V, Mn, Ni, Zn, and Sn. Hazardous elements such as Co, Cl and Cr were detected in more than 50% of the particulate matter (PM) analyzed. The PM analyzed from jeepney 1, which was manufactured in 1980 contained the most number of hazardous elements that have a high frequency of occurrence. These include Pb and Hg which were found only in one or two PM in jeepneys 2 and 3. But for jeepney 1 traces of Pb and Hg were detected in more than 50% of the PM. Another hazardous element that was found only in the PM coming jeepney 1 is Se.
