Abstract

This project aims to identify some atmospheric organic compounds that can be considered tracers of specific emissions. We will determine the polycyclic aromatic hydrocarbons and n-alkanes presented in the atmospheric particulate matter collected inside important tunnels and at an urban site in São Paulo City. Some chosen compounds will be important to identify the anthropogenic emissions and other to identify the biogenic emissions.
