Air pollution source
various sources that causes air pollution caused by emissions and air pollution in the confused substance that is causing air pollution, causing this comes from various sources, which there are several ways of
.Such a split, based on characteristics of flow movement of origin may be divided into 2 categories: non-mobile sources (stationary source) such as industrial operations in the factory. Fuel combustion in the residential and (Mobile source): combustion of fuel in car engines, ships, or aircraft, or by the factor causing air pollutants can be divided into 2 source is human sources. Create a source (source man-made) and formed by nature. Source) in this case I will mention air pollution origin divided by group. Categories of origin as follows:
1. action arising from the sources of the air pollution of human origin
, this type of activity of the human nanaprakan:
.1 transportation system) The car is considered to be the major reason that causes air pollution. Especially in the major cities where there are a lot of Sprint car and a traffic jam, such as Tokyo, New York, Los Angeles and Bangkok, Thailand, etc. 3 points is from evaporation from the reservoir and other systems from which pollutants the exhaust system cooling exhaust is dangerous, and most are coming from the combustion occurs inside the engine include hydrocarbons compounds such as. The substance rose matik-hydrocarbon Carbon dioxide, nitric oxide, nitrogen dioxide and carbon dioxide (CO2)
.Pollution that comes out from the exhaust system, it will be more or less depending on the rates of air/oil (air fuel ratio) that caused the burn has the most complete is quite. By that point, complete combustion is gas. Carbon monoxide But nitrogen oxide gases This happens because most of these conditions will result in additional oxygen is one of the best. On the contrary, If the air/fuel ratio dropping In this range, the result will be burning to Wicks. And more carbon dioxide (CO2) and nitrogen oxide gases, which said that the combustion occurs. The engine type is not completely there is a relationship with the amount of pollution that is released from the vehicle. But at the same time, the return of particles and nitrogen oxide emissions come out above
.In addition, the work of the engine during the various usage, it affects the amount of air pollution as well as shown in table 2
.2) combustion of fuel in the House. Burning is the process that is necessary to sustain human life. Doing daily activities within the home. Fuel combustion is to be used for heat energy
.Various benefits such as to cook food. Heating in the House, where the burning of such fuels can cause many types of unwanted gases such as carbon dioxide (CO2) Nitrogen dioxide Like smoke
Etc.
3) Institutional trading business and Government agencies. The business or operation of the institutions and agencies of the State shall use fuel combustion to cause energy to exploit as
.Will cause many types of air pollutants in the air get mixed in, as well as the burning of fuel in the building House
?4), industrial, and metal smelters melt Oil refining industry, chemical industry, food industry, causing the impurities in the air is different in both quantity and quality. In General, industrial And as a citizen accused of a crime punishable by as much as can be seen at henkhwan released from the vent hood is clear. Air pollutants originating from industrial plants, including most of the dust.
CarbonSmoke, sulphur dioxide Carbon dioxide (CO2) Carbon dioxide Toxic gas nitrogen oxide gases and many other type 5) power plant. The power plant will be able to export electricity available. Need to have. Fuels such as fuel oil Different types of coal and other fuel to produce energy. To apply heat to electricity continues. Burning of these fuels causes the substance. The major air pollution. Gas, nitrogen oxide and particle contamination of additives
.6) from the burning of garbage and sewage in the municipal or community with a population density among which there may be some waste disposal by incineration. In addition, various commercial ventures in the industry, including the acts of the State. Incinerator, regardless of whether it is any way causing air pollutants due to the burning of wastes, including compounds and nitrogen oxide hyper-rakhapon. Oxide of sulphur, carbon monoxide and carbon dioxide etc.
