Impact of Diesel Engine Exhaust Gases on Environmental Pollution and Human Health

Fine particles that can be found in the exhaust gases of diesel engines and have a diameter of 2.5 mm and ultra-fine particles of 0.1 mm in diameter are mainly products of the combustion process. Experiments on animals have proven that the particulates from the ambient air can cause damage to the lungs and can even end fatally. Therefore, it is necessary to reduce the mass of fine particles in the atmosphere and the number of ultra-fine particles. Numerous studies of experiments on animals have proven the toxicity of these particles. The air saturated by particles resulted in cardio-pulmonary diseases in animal models. The epidemiological studies have shown the interdependence of the increase in mortality and morbidity, especially in the elderly and persons suffering from respiratory ailments and cardio-vascular diseases. A hypothesis has been set that the ultra-fine particles cause inflammatory reactions in alveoli and interstitium resulting in the increase of blood coagulation and deterioration of the condition in persons suffering from the problems in cardio-vascular system.
