Abstract

The principal objective of this project is to quantify the transfer and transport of polycyclic aromatics (PAHs) associated with particulate material, between the atmosphere and the ground, in remote and urban areas in the State of São Paulo. The physical-chemical characterization of this material will be undertaken under different meteorological conditions (wet and dry periods) from fixed sampling units. Thus, we will study the morphological parameters (size and shape) and the chemical composition of the aerosols, as well as the physicochemistry of the solutions that circulate in the atmosphere-ground interface. With regard to the chemical composition, in addition to the polycyclic aromatics, we will determine the fundamental composition (Al, Mn, Fe, Pb, Cu, Zn, etc.) and the soluble species (larger cations and anions). This characterization will make it possible to establish relationships between the different descriptive parameters of the particulate material in suspension in the atmosphere, associated with the variations resulting from the meteorological conditions and from anthropic activity. It will also make it possible to evaluate the impact of this material on the soil. (AU)
