Air Pollution Plagues India


Dust from construction

When the quantity of dust decreases the quality of air we breathe in, life on Earth starts to deteriorate. It is a serious problem that every person in India faces. When increasing urbanisation uproots the green protectors of the Earth (the trees), vast green lands and fields in the name of development, are we not depriving ourselves and the future generations the right to live on Earth?

Air pollution is a worldwide concern. There have been many investigations into what causes air pollution and the exact methods that work best in the prevention of air pollution. Air pollution is the presence of high concentration of contamination, dust, smokes, etc., in the general body of air we breathe.

Dust and smoke are the two major components of particulate matter. Car emissions, chemicals from factories, dust, and pollen and mold spores may be suspended as particles. The dust or particle pollution is a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small that they can only be detected with an electron microscope.

These particles come in many sizes and shapes and can be made up of hundreds of different chemicals. Some particles, known as primary particles, are emitted directly from a source, such as construction and demolition sites, paved and unpaved roadways, fields, smokestacks or fires, parking lots, storage piles, handling and transfer of materials, and open areas. Others form in complicated reactions in the atmosphere of chemicals such as sulphur dioxides and nitrogen oxides that are emitted from power plants, industries and automobiles. These particles, known as secondary particles, make up most of the fine particle pollution in the country.
