Abstract

The project is aimed at the evaluation of the chemical composition of the wet precipitation in the basin of the river Piracicaba. Wet precipitation collectors will be set up all along the basin and the rain will be sampled throughout the year, for the analysis and interpretation of inorganic and organic components and their relationship with the acidity of the precipitation. We will also evaluate the transport of masses of air all along the basin, to understand the origins of the precipitation and correlate the occurrence of acidity with natural or anthropogenic sources. Based on the knowledge about the atmospheric phase of the hydrological cycle, it will be possible to add this important information to the understanding of the biogeochemistry of the basin of the river Piracicaba.
