The air of the future is the air we breathe today. It is our source of life, tomorrow’s generation depends on it. Air is composed of 78.084 Nitrogen, 20.946 Oxygen, 0.934 Argon, 0.033 Carbon Dioxide, 0.003 rare gases (all are in mole %). The breakdown of air composition, water vapor and inert gases, cause it to lose its purity.
Air pollution is everyone’s burden. Not only have human beings experienced the effect it brings. But different groups of individuals are likewise, affected by air pollution in different ways. Some individuals are much more sensitive to pollutants than others. Young children and elderly people often suffer more from the effects of air pollution. People with health problems such as asthma, heart and lung diseases may also suffer more when the air is polluted. The pollutants coming from different sources affect primarily our health. Particulate Matter (PM) a type of pollutant composed of particles found in the air, including dust, soot, smoke and liquid droplets can be suspended in the air for long periods of time. Some particles are large dark enough to be seen as soot or smoke. This may cause a wide variety of impacts on health and environment. Some of the health effects occur in the respiratory system, which results to difficulty in breathing, aggravated asthma, chronic bronchitis or even premature death. PM also causes the reduction of visibility. Even the water people drink can be exposed to the particles carried over long distances by wind.
A colorless, odorless gas formed when carbon in fuel is not burned completely is another common pollutant, popularly known as Carbon Monoxide (CO). Found in the motor vehicle exhaust and in metal and chemical manufacturing industries it contributes more than 85-95% of all CO emissions nationwide.
