【 摘 要 】

This work starts with a historical perspective of the social and scientific progress related to the understanding of the atmospheric aerosol. Its origin, physical, chemical and optical characteristics, as well as its environmental behaviour are described, retracing the evolution of the concepts related to this subject over the last centuries. The main sources that contribute to atmospheric particulate matter and the modern understanding of its formation processes and constitution, focusing on the chemical pathways leading to it and on its organic components are presented. This discussion is complemented with recent evaluations of the quantities emitted by primary, secondary, biogenic and anthropogenic sources and the effects due to accumulation or dispersion of aerosols, justifying the chemical and environmental interest they engender.
