Air pollution

Abstract

If we consume 1kg of food, 2 kgs of water, we consume 20 kgs of air daily (Lacombe, 2015). With each breathe we fill our lungs with air, composed of nitrogen and oxygen gases, with these gases we also introduce other gases and particulate matter, some of which are toxic to our health. These toxic gases and particulate matter came from our cars, our heating system, our vegetation and our smoke, another portion came from natural forests fire and from earth surface dust. Earth atmosphere is like an apple peel compared to earth volume, but it is essential for the life of every living organism on earth, without this atmosphere, earth is not a good place to live in. Air is the most important element for us to live. We can stand hunger and thirst for days, but we can’t stand life without breathing for more than 10 seconds. Fresh natural air constitutes naturally from nitrogen, oxygen and other gases such as argon, ozone, hydrogen, water vapor and traces of other gases. Pollution in any system can be defined as anything added to the system and causes a change in its physical, chemical or biological structure and causes a deviation in its proper mission. Air pollution is a very critical matter, hence air is a vulnerable system which can be affected quickly by anthropogenic activities and natural pollutants. Air pollutants are divided into two main types. Primary pollutants, which are introduced into air either from anthropogenic actions, like car emissions heating systems and industrial emissions, or from natural sources lake emission of volatile organic compounds from vegetation and trees. These primary pollutants are pollutants by themselves and are have direct effect on human he bodies and buildings. Second, Secondary pollutants, which are derived from the reactions of primary pollutants with ozone, oxygen and water vapor. In this exam, the answers of the supplied questions illustrates many of air pollution schemes and points out to the dangers of air pollutants on health and nature.
