INTRODUCTION PAHs (Polycyclic Aromatic Hydrocarbons ) Naftaleno S Pireno Benzo (c) fenantreno Coroneno Benzonaftotiofeno Benzo(a)pireno One of the greatest challenges in air pollution research, especially which is focuses on the study of PAHs, is the development of systems and sampling procedures to obtain more accurate, reliable and representative information about concentrations of these compounds and their variation in time Laboratorio de Química Ambiental - UTFSM Dr. Francisco Cereceda
