Abstract

The present research project aims to study the composition and morphology of the aerosols in the city of São Paulo and, together with the meteorological parameters and Pb isotopes, trace the possible sources of natural and anthropic emissions. The research will involve seasonal campaigns for the collection of fine (PM2,5) and coarse (PM1O) particles in periods of 12 hours, enabling the modeling of the polluting sources and the dispersion of their pollutants, by means of the evaluation of trajectories of air mass. The same collection systematics will be applied in a remote area, the most pollutant-free possible in order to characterize the region’s background system. What distinguishes this project from those carried out already in the city will be the association of several analytical techniques and the use of Pb isotopes as tracers of pollutant and natural sources, already widely used in countries in the Northern hemisphere and recently developed in Brazil for environmental studies.
