Damage caused by automobile exhaust gases

In the busy streets, is a lot of light blue smoke from the queues of motor vehicles, commonly referred to as car exhaust fumes. Smells of car exhaust not only, but also cause dizziness and nausea, Impact on human health. Along with the dramatic increase in the number of cars jammed in a very common problem. was the "catastrophe Auto" is formed, and the car was because it is extremely harmful exhaust gases.

There are different typesof harmful chemicals in the car containing gas emitted mainly as follows:

Exhaust System

Before solid particles suspended
The composition of the solid particles is very complex. It has a strong adsorption capacity, which can accommodate all types of metal powders and strong carcinogens such as benzopyrene and pathogenic microorganisms. If the suspended solid particles enter the human lungs with air, will be stored in various parts of the airways, so that respiratoryDisease. In addition, airborne particles directly to the skin and eyes, which block the hair follicles and sweat glands cause, dermatitis, conjunctivitis and skin, and even lead to the cornea.

Second, carbon monoxide
During and carbon monoxide into the bloodstream through the respiratory tract and this will combine with hemoglobin and carbonyl hemoglobin. The weaker is the function of blood to the blood to different tissues, transport, damagethe central nervous system dysfunction due to human emotion, reaction, understanding, memory, and so on. More seriously, it damages the circulatory system and threatens life.

Third, nitrogen oxides
Nitrogen oxides are mainly related to nitric oxide and nitrogen dioxide, the gas is harmful to human health, particularly on the respiratory system. When the concentration of nitrogen dioxide in the air is too high, it is defects in the human respiratory tractSystem.

Fourth, the hydrocarbons
Currently, people are not aware of the direct damage of hydrocarbons on human health. However, when nitrogen oxides react with hydrocarbons when exposed to UV rays, will include the creation of a sort of light blue smoke, ozone, aldehydes, nitric acid and many other complex compounds. The most important loss of photochemical smog on the human body is to stimulate the eyes and mucous membranes of the upper respiratory tract that cancause eye irritation and inflammation of the larynx.

In addition, there are other components in automotive emissions of harmful chemicals such as lead, dioxin, sulfur dioxide, and so on, which greatly threaten human life.
