1.The concept of air pollution Air pollution is the presence of a foreign substance or an important change in the composition of air, clean air does not make or cause smells, unpleasant odor or decreased vision (due to dust) 2. Causes of air pollution ( Nature Due to the natural phenomenon caused: volcanoes, forest fires, dust storms, the breakdown of plant and animal body. Synthesis of polluting elements are naturally very large but relatively evenly distributed throughout the world, not concentrated in one area. During development, people have adapted to these sources.


Volcanoes Forest fires



Dust storms Dead animals
( Industry This is the largest source of contamination of man. The pollution is the burning of fossil fuels: coal, oil, gas generated CO2, CO, SO2, NOx, unburned organic matter of all: soot, dust, process losses , leakage of technological lines, the transport process of volatile chemicals, dust. ( Features: Industry sources have high concentrations of toxic substances, often concentrated in a small space. Depending on process technology, production scale and the amount of fuel used hazardous materials and hazardous material will be different.



The plant’s emissions
( Transport This is a major source of pollution to air, especially in urban areas and densely populated areas. The process creates air pollution are combustion engine fuel: CO, CO2, SO2, NOx, Pb, the soil dust entrained in the moving process. Considering each means the concentration of pollution is relatively small, but if large traffic density and planning terrain, bad roads, it will cause severe pollution to the roadside.




Emission from vehicles

( Activities Pollution sources are mainly the work of cooking fuel use but particularly local pollution in one household or several households around. Polluting agents mainly CO and dust. 3. The consequences of air pollution ( Impact on health   Exposure to high concentrations of dust in the air, especially in urban areas with high traffic density and the area around the base of producing construction materials, will be at risk of developing respiratory diseases tract and lung disease. The common pulmonary tuberculosis than current lung infection; respiratory system cancer (lung, pleura) us airways disease (asthma, chronic obstructive pulmonary disease ...) .    ( For the ecosystem ( Land contamination may become infertile, unsuitable for crops. This will affect other living organisms in food webs. ( Smoke and fog reduce sunlight that plants get to make the process of photosynthesis. ( The animals can invade, compete and occupied habitat for endangered native species, thus reducing biodiversity. CO2 generated from the factories and passing vehicles also increases the greenhouse effect, making Earth Day a hotter, ecosystems are available gradually destroyed.


Measures to reduce air pollution.
( Focus factories pollute the environment in industrial zones.


( Program control industrial pollution. Program monitoring air quality.



( Communication activities on environmental protection


( When you come near, you should use bicycles or walk.




. ( You should use bus or carpool when going to work, school, recreation and entertainment. reduces the cost and limit traffic congestion, reduces pollution


( Should your motor maintenance once a year to increase durability and reduce car exhaust fumes into the environment


( Keep planting and protecting trees.








=> Currently air pollution exacerbated by, affected by emissions from vehicles, buildings, works and service production. Air pollution is seen as the silent killer. According to the World Health Organization (WHO) every year the world has about 2 million children die from acute respiratory infections, 60% of cases related to pollution khi.Cung with development of industrialization and modernization of the air pollution is increasingly urgent issues that need attention. Environmental protection is to protect their own health. Because the noodles so please join hands for a clean green environment.
