Abstract

The diesel-powered vehicles contribute significantly to the increase in air pollution, since they have a large percentage of emissions of particulate matter. The DEP (Diesel Exhaust Particulate) as one component of particulate matter from air pollution, may in many cases lead injury of the airway, may induce oxidative stress the cell, causing as cellular events consequences, disruption of mitochondrial function and other damage, which may even lead to cell apoptosis. The purpose of this project is to study the influence of DEP in the cytotoxicity of the respiratory tract areas cells and how it affects the metabolism of mitochondria. This study will utilize DEP collected from buses school and analyzed by techniques for determining concentrations of organic and inorganic material, following the analysis of toxicity and mitochondrial integrity indicator in BEAS-2B cells.
