Airborne fine participate matter, during the 2004 New Year fireworks festivities, were collected by a low-volume impactor on the third floor of the science and technology research center building (14033.971'N,120059.524 'E) approximately 30m above sea level located at the LIDAR station in De La Salle University, Malate, Manila in order to investigate the characteristics of fine particle aerosols during the new year festivities. Morphologies and elemental composition of individual particles were analyzed using scanning electron microscope and an energy dispersive x-ray spectrometer. Elemental analysis on the fine particles revealed various elements used for fireworks such as Al, Ba, C, Ca, Cl, Cu, Fe, K, Mg, Na, O, S, and Zn.
