The cause of air pollution
causes significant air pollution are:
1. Vehicle engines Automobile exhaust is the most problematic substances out of the car, namely. Carbon monoxide, hydrocarbons, oxides of nitrogen And sulfur Then, about 55% of the hydrocarbons coming out the exhaust pipe from 25% out of the crankshaft and the other 20% is due to the volatility in the carburetor. And fuel tanks Oxides of nitrogen Nitric oxide (NO), nitrogen dioxide (NO2) and nitrous oxide (N2O), almost all coming from the exhaust. It is directly toxic to humans In addition, lead in gasoline to increase the amount of lead in the air, super kind with
two. Smoke and toxic gases from industries
- from chemical plants, oil refineries, power plants, including the beer distilleries, sugar plants, paper mills, ore. Dyeing factory The glass factory Plant bulbs Fertilizer plant And plant acids
- the energy generated by burning fossil fuels such as coal, oil, chemicals, natural gas, the increase in prices of various substances such as other hydrocarbons, oxides of nitrogen and sulfur in the atmosphere
3. Sources of dust, including the area under construction. The crushing plant, cement factory, a textile factory manufacturing caustic soda kiln coal mining, coal mill crematorium
4. Sources of sewage sludge and solid waste, including food waste
5. Smoke from burning fields and forests burned by cigarettes
6. The nuclear test Causing radioactive fallout
7. Radiological examination and treatment The use of radioisotopes The lack of an accurate measure. Climate protection was
eight. Air pollution caused by natural phenomena such as volcanic eruptions, earthquakes, forest fires, radioactive gas that occurs naturally as toxicity due to this relatively minimal since the distant origins. So into the environment, humans and animals have less impact of air pollution first. Damage to health polluted air cause sinusitis Diseases of the respiratory disease related to blood circulation. The effects of long-term exposure may cause fatal damage to buildings and appliances 2. The structure, made of metal, causing erosion. The books and art were damaged 3. visibility worsened. And affect the air temperature decreases lower than normal. Visibility worsen Causing an accident in the road, air and water.
