Air pollution, our planet is enveloped by a layer of the atmosphere, about 15 km thick layer of the atmosphere consists of nitrogen, oxygen, water vapor and dust. And Micro-organisms in these gases. Gas that is most important to the existence of. Life on Earth is a layer of gas and oxygen gas atmosphere with enough oxygen. To live with a thickness of 5-6 km. This usually consists of various gases is relatively stable nitrogen 78.09% 20.94% oxygen, carbon dioxide and inert gas. 0.97% for a fixed amount of gas above, we hold that the fresh air, but whenever a component of climate change to the amount of dust and gas smell smoke, vapor, steam, soot, and the radioactivity in the atmosphere was excellent. Too many of us call such conditions as "bad air" or "air pollution" , the definition of air pollution, air pollution, climate means that there are contaminants in higher than normal levels for the time. Long enough to cause harm to humans, animals, plants or other assets may occur naturally, such as dust storms. Volcanic eruptions, earthquakes, forest fires, natural gas, air pollution occurs. By nature is very little danger to humans. The origin is far and amounts to the condition. Environment of humans and animals is minimal. Cases caused by human activities, including pollution from the exhaust. Of industrial production from agricultural activities by evaporation. Some of the gas Caused by garbage and waste. As a source of air pollution sources of air pollution in Thailand is divided into two main groups, the vehicles , industrial vehicles causing air pollution in urban areas restricted to large jobs. But the problem of air pollution from industrial plants. The only problem areas scattered across the country, both in rural and urban origin of vehicles , rapid economic growth of the country's agricultural sector. The industry, making the center of Bangkok's business and population growth has increased dramatically. The demand for travel and transportation more. Cause traffic problems in a coma. Others are more severe and more. Traffic congestion causes cars moving at low speed. To stop and off frequently. The oil was burning up. The incomplete combustion of fuel. Ventilation and exhaust emissions in proportion to the increase. The area near the road, with traffic jams. There will be more severe air pollution problems. In areas where the traffic is flowing freely. Discharge of pollutants into the atmosphere caused. Transportation, including carbon monoxide Oxides of nitrogen gas Hydrocarbons Dust particles smaller than 10 microns, lead and sulfur dioxide from industrial sources of air pollution sources. Industrial generator Caused by burning fossil fuels and manufacturing processes. Which is a major cause. Impact on air quality and may result. Health effects of ...
