[Respiratory effects of diesel exhaust emission].

Adverse effects of diesel exhaust is being now a subject of many recent studies. These various outcomes and especially respiratory changes are due to high concentration of different polluants within diesel exhaust particles. To date, it have been demonstrated that diesel emission increase the airway allergic reaction as rhinitis and asthma. In addition, to those side effects, it is proved that diesel exhaust is a probable human carcinogen based on evidence. Many epidémiologic evidence found a significant increase in lung cancer risk. However, some studies have provided contradictory results due to concomittant exposure to other polluants, tobacco exposure and difficulties to extrapolate findings in animal models into humans.
