Estudo De Sistemas De Medidas Para a Determinação De Hidrocarbonetos Policíclicos Aromáticos Em Amostras Ambientais Veiculares

Abstract

Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that have two or more aromatic rings and their emission sources are mostly anthropogenic, such as burning fossil fuels in vehicles. Due to their properties, these compounds are toxic in nature and are considered to be potential carcinogens, requiring attention to their detection in the environment. Several studies have already been conducted for the construction of detection systems, however, the methods are very expensive and complex. In view of this scenario, the objective of this work was to identify these measurement possibilities already used so that a new, simpler and cheaper system for determining PAHs can be proposed. In order to do so, it was carried out a bibliographic survey in order to build the necessary theoretical foundation for the proposed system development.
