Air pollution is defined as the introduction of biological molecules, particulates or any other harmful materials into the atmosphere which will cause disease or even death to human being, cause damage to other living organism, affect the crops, and even buildings. The atmosphere is a natural gaseous system which is essential for life on earth. Ozone layer depletion is a known threat which is also caused by Air Pollution. The two of the world’s most toxic pollutions are Indoor air pollution and urban air pollution. According to a study, air pollution has caused a whooping 7 million deaths in the world. The chemicals in the air can be of natural means or manmade. The maximum amount of the pollutant in the air is due to man factor. The pollutants are classified into primary pollutants and secondary pollutants. The primary pollutants are pollutants that are emitted into the atmosphere directly, like the ash from the volcanic eruption, carbon monoxide from the motor vehicles, sulfur dioxide from the factories etc. While the secondary pollutants are not emitted directly, while they are the result of the primary pollutants. When the primary pollutants react or interact with the air, they form into a pollutant. Ground level ozone is an example of secondary pollutant, but any way they are caused by primary pollutants, so if there is a control of primary pollutant, then the air pollution can be reduced to a certain extent.
Here are some of the pollutants that are emitted into the atmosphere by human means,
The secondary pollutants include smog, ground level ozone, Peroxyacetyl nitrate, organic pollutants. The sources of air pollution are,
Natural sources are,
The health effects of air pollution are,
The air pollution is causing a lot of damage to the environment, if the control measures are not implemented fast, we will have to live in a surrounding with full of dust and non breathable gases. There are lot of air pollution control techniques and land use planning strategies. The land use planning involves zoning and transport and infrastructure planning. This should be implemented in many developing and under developing countries in order to control the air pollution.
The use of electric vehicles should be used more in the place of petrol or diesel vehicles. Cleaner fuels can be used such as the bioethanol, bio diesel etc. The scientists have found a new gas to reduce the air pollution and that is Titanium dioxide which will break up those radicals, the VOC’s and NOx by emitting free electrons. A prof of University of Sheffield made a 10*20 meter poster which had Titanium dioxide, and was placed on a building roof so as to absorb the polluted air. This poster could absorb the pollutants from 20 cars each day.
The control devices are,
Air pollution is a major havoc in future and if we don’t stop controlling it, we will have a huge task in front of us to clear off.
