pDiesel exhaust is a complex mixture of gases and particles that is generated from the combustion of diesel fuel. It is a major contributor to air pollution, particularly in urban areas, and is associated with a range of adverse health effects, including respiratory diseases, cardiovascular diseases, and cancer. The molecular aspects of diesel exhaust exposure on lung health have been extensively studied in recent years, with a growing body of evidence indicating that diesel exhaust exposure can have profound effects on the molecular processes involved in lung function and health.ppOne of the key ways in which diesel exhaust exposure affects lung health is through its impact on oxidative stress and inflammation. Diesel exhaust contains a range of reactive oxygen species and free radicals, which can induce oxidative stress and inflammation in the lung tissue. This can lead to damage to the DNA and proteins in the lung cells, and can contribute to the development of respiratory diseases
