abstract = "Chemical and physical properties of fine particulate matter (PM
2.5 ) are related to emission sources. In order to determine
chemical and physical differences, PM 2.5 samples were collected
at urban, rural and industrial areas of the metropolitan region of
Rio de Janeiro (MRRJ), Brazil. The chemical characterization of
the samples was performed using ion chromatography (IC) and
inductively coupled plasma mass spectrometry (ICP-MS), while the
physical characterization was done by scanning electron
microscopyenergy dispersive spectrometry (SEM-EDS). Through the
use the Hybrid Single-Particle Lagrangian Integrated Trajectories
(HYSPLIT) model, it was observed that all the studied sites
presented the influence of ocean air masses. The industrial and
rural sites showed to influence of continental air masses too,
that carried aerosols with greater UV absorption compared to those
observed in trajectories originating in the Atlantic Ocean. Among
analyzed species, NO 3 \− and SO 4 2\− ions and V,
Pb and Sn elements were predominant in the urban site whereas in
the rural and industrial sites Na + , SO 4 2\− were the
major ions and Na, Zn and Ba were the elements with the higher
concentrations. Through SEM-EDS analysis, the particles were
classified into two categories, the first in terms of the
morphological similarities and the second in function of the
elemental composition. As observed in ICP-MS analysis, the
elements K, Al, Ca, Fe, Cu, Zn, Ba and Mg were detected also in
the individual particles analysis by SEM-EDS. These results showed
that C, O and Si were predominant elements at all sites. The
morphological and chemical analyses indicate that the influence of
vehicular emissions as a common source at all sites. The analyses
also showed that the urban sites present particles with more
diverse morphologies compared to rural and industrial sites.",
