Oxides of Nitrogen, noi: Nitrogen oxides (NOx) are produced by combustion of all fossil fuels including coal-and gas-fired power stations and motor vehicles.

Secondary pollutants are the ones that are formed as a result of reactions between primary pollutants and other elements in the atmosphere. Air pollutants are direct pollution cause, in other words they are the actual polluting agents, which directly affect the health of living beings help as well as the wider environment. Major Air Pollutants that Affects Environment: Some of the major air pollutants that pollutes the environment are:. Sulphur dioxide (SO2 sulphur dioxide (SO2) is a colourless gas with a pungent, suffocating odour. SO2 is corrosive to organic materials and it irritates the eyes, nose and lungs; therefore it is quite dangerous air pollutants. Sulphur is contained within all fossil fuels, and is released in the form of sulphur dioxide during fossil fuel combustion.

Industries are the main cause of plan anthropogenic air pollution. The global industrial development gave rise to a large number of economic sectors, each generating air pollution to some degree. So these economic sectors act as pollution causes in their own way. Some major sources and types of major air pollutants produced by each of them are shown in Table 3: Air pollutants are basically the waste products generated by the above mentioned economic sectors. They come in the form of gases and finely divided solid and liquid particles suspended in the air (aerosols). Air pollutants can also be of primary or secondary nature. Primary pollutants are the ones that are emitted directly into the atmosphere by the sources (e.g., power plants).

This is a factor that building construction sites also take into account, since the presence of methane in the airways of the buildings can lead to dire consequence. (v) Radon Expulsion: Nuclear elements like uranium are found inside the earth surface, and when these elements decompose they release a noble gas known as Radon into the atmosphere. This gas is highly radioactive in nature, and it can cause some serious health damage to people who breathe the air that contain. Interestingly, after smoking, radon intake is the second largest contributing factor to lung cancer in human beings, so all possible measures to prevent the spread of Radon must be taken. Other factors like the dispersal of large amount of pollen from flowers and the emission of vocs (Voltage Organic Compounds) which get oxidized and transformed into aerosols from plants and trees also lead to air pollution which is not caused by man-made sources. There are plenty of natural causes of air pollution that are out of our control as well.

There are several active volcanoes that are found around the planet today, and along with the air pollution that they cause, they also lead to a serious danger to life forms. Carbon dioxide and sulpur dioxide are the primary sea gases that are released during volcanic eruptions, and these lead to dire consequences to the earths atmosphere and to all the life forms that reside there. Other gases like hydrogen sulphide, hydrogen chloride, hydrogen fluoride, carbon monoxide, halocarbons and some metal chlorides are also released into the atmosphere in smaller traces. The materials released also lead to acid rain in many parts, and the volcanic ash that follows disrupts air travel dissertation and many other activities.

The recent eruptions of Eyjafjallajokull over Iceland in 2010 also led to several restrictions in air travel over Europe. (iii) Wind Erosion : Though dust particles and dirt do not cause toxic effects on the human body, they are capable of inducing many respiratory diseases in human beings. These dust particles move around in the atmosphere due to strong winds, especially in geographical areas where wind erosion is a common occurrence. This factor is not a very major contributor towards air pollution, but it does play a small role and is one of the most underestimated types of air pollution. (iv) Methane Expulsion : Farm animals like cattle release methane into the atmosphere during the end stages of their digestive cycles. Methane gas affects the ozone layer in the atmosphere since it is a very potent greenhouse gas, and it is also highly inflammable when it combines with other elements in the air. Moreover, it can lead to severe asphyxiation if someone is trapped in a closed room with the presence of methane gas in the air.

Causes of Air Pollution: Natural causes of Air Pollution: Natural causes of pollution may include forest fires and volcanic eruptions as well as vegetation, oceans and decay processes in soil. Fossil fuels (oil, gas coal) are the largest anthropogenic sources of air pollution-they are widely used in industry and everyday life.


But they are not the only ones. The biggest source of using fossil fuels is running of power plants and automobiles that combust fuel. These two sources are responsible for about 90 of all air pollution. Some cities suffer severally because of heavy industrial use of chemicals that cause air pollution. Places like mexico city and sao paulo have some of the most deadly pollution levels in the world. (i) Forest Fires : A fire that occurs in a highly infested area through natural causes is known as a bush fire, and this is a very potent natural source of air pollution. There are several different causes that lead to forest fires, and the fact is that they are caused naturally without any human intervention.
