The result of car exhaust Harms

The result of car exhaust Harms

Exhaust System

In the busy streets are a lot of light blue smoke from the queue of motor vehicles, commonly referred to as car exhaust emissions. You smell like car exhaust not only foreign, but also cause dizziness and nausea, to human health. Along with the dramatic increase in the number of jam of cars has become a very common problem. The "car crash" was formed and led from the exhaust car is extremely harmful.

There are severalTypes of harmful chemical compounds contained in the flue gas cars, primarily as follows:

Before solid particles suspended
The composition of the particulate solid is very complex. He has a strong adsorption capacity, which take all kinds of dust and strong carcinogens such as benzopyrene and pathogenic microorganisms. When the suspended solid particles enter the human lungs with the breath, will be stored in various parts of the airways, so that respiratoryDisease. In addition, airborne particles can also direct contact with skin and eyes lead block, the hair follicles and sweat glands in the skin, dermatitis and conjunctivitis is, and also damage to the cornea.

Secondly, carbon monoxide
If the carbon monoxide in the blood flow through the respiratory system in place, combined with the hemoglobin and hemoglobin carbonyl form. The weaker is the function of blood to carry blood to various tissues, damagecause dysfunction of the central nervous system of human emotion, reaction, understanding, memory, and so on. Much more seriously, could damage the circulatory system and threatens human life.

Third, nitrogen oxides
Nitrogen oxides are mainly related to nitric oxide and nitrogen dioxide, two gases are harmful to human health, particularly on the respiratory system. If the concentration of nitrogen dioxide in the air is too high, it is a dysfunction of the human respiratory tractSystem.

Hydrocarbons quarter
Currently, people are not aware of any direct hydrocarbons on human health. However, when nitrogen oxides react with hydrocarbons when exposed to UV rays, creating a sort of light blue smoke, to which the ozone, aldehydes, nitric acid and many other complex compounds. The most important loss of photochemical smog on the human body is the stimulation of the eyes and mucous membranes of the upper airways, which cancause eye irritation and inflammation of the larynx.

In addition, there are other chemical components of harmful automobile emissions, such as lead, dioxin, sulfur dioxide, and so on, that human life in danger.
