Air pollution occurs when the air is contaminated with waste. Industrial waste is the main sources of air pollution , and can be in the form of gases or particles .
And produce such waste primarily from the burning of fuel used in the operation of motor vehicles and heating homes , and also produces industrial processes and the combustion of solid waste
The rapid growth in population and in the industrial field, and the increase in the number of vehicles and aircraft engines make air pollution increasingly serious problem in many big cities ; The air over these cities is often imbued with pollutants harmful to human health . And also caused air pollution damage to plants and animals
The main sources of air pollution
Rich in the cities where there are many coal furnaces and power stations , high rates of sulfur oxides . The cities in which abound industries Vtkon levels of organic compounds are also high. But car exhaust in most Western cities cause in the presence of most of the nitrogen oxides and carbon monoxide pollution to the air.
Weather conditions may help known coup warming in contaminants are above a certain area.
And transportation. Represents the aircraft , cars, ships , trains and other major source of air pollution. And turn on the gas contains carbon monoxide , hydrocarbons and nitrogen oxides . And help nitrogen oxides in the air to produce a kind of oxygen known as ozone . Ozone reacts with hydrocarbons component form of air pollution, knows Haze smog .
Industrial waste. Such operations contribute significantly to air pollution
Combustion of solid waste
Other sources. Include other sources of air pollution spraying chemicals , forest fires and fires installations. It also produces pollution from the burning of forests and herbs
Effects of air pollution
Health. When people breathe polluted air often remain impurities inside the lungs , which could lead to the aggravation of some respiratory diseases such as asthma and bronchitis .
Agriculture. Cause air pollution irreparable damage to crops and livestock in countries where there are heavy industries and crowded roads . Plants can not grow along with many of the ways this country ; because the cars emit fumes lead to her death . And air pollution could hurt fruits and vegetables and cereal crops .
Air pollution control
There are many ways to reduce the degree of air pollution from stationary sources such as factories and furnaces , fuel and electric power production plants . For example, can the plant to install equipment designed to reduce the amount of pollutants emitted from it. It can also turn into a method of manufacture or burn for fuel , leading to reduced air pollution .
The plant can also switch to the use of more fuel purity to reduce the degree of contamination .
