Abstract

This project has the objective of understanding the sources, composition, transformations and possible environmental implications resulting from the emission and presence of some nitrogen compounds in the atmosphere in the central region of the State of São Paulo. To attain these objectives samples of the atmosphere will collected throughout the year for the determination of the average composition of the species NO, NO2, NH3, ozone in the gaseous phase and NH4+, N02-, NH+4 in the particulate matter and in the rainwater collected in the region. By way of result it is hoped to create a model for emission, transport and deposition of these compounds in the region and make it possible with this knowledge to understand possible effects on the atmosphere.
