ENVIRONMENT 2
Introduction:
Air is one of the basic requirements of life. It is a mixture of various gases such as nitrogen,
oxygen, argon, carbon di oxide etc. all these gases and their fixed proportion constitute the pure
air that can support the life of the living organisms on Earth. Any alteration or modification in
the constituents and proportion of the gases leads to polluted air 1. Along with this, presence of
some unwanted solid and liquids in gases or atmosphere results in air pollution. This pollution is
great cause of deterioration of human health. India is the country that is facing the air pollution
issues since years. Delhi, the capital of India is one of the most polluted cities in the country.
This literature helps in analysing the sources that are the major cause of pollution in Delhi along
with the study of some effects that is deteriorating the life in the city.
Air pollution is the one of the major reasons why Delhi people are facing so much of health
issues. There are many changes that have been experienced in the climate and air quality of
Delhi since recent years. There are various reasons for changes and rise on the sir pollution in
Delhi. One of the causes is vehicles 2. Many strategies have also been implemented in order to
reduce the pollution that is generating from vehicles in Delhi and near NCR region. Controlling
the pollution in India is very difficult and challenging. The interaction of urban and rural sources
supports the pollution to increase more. Despite of introducing various procedures and policies
for controlling air pollution, there is no improvement observed in India and especially in Delhi.
Several studies have been conducted on Delhi’s air pollution and air quality. During 2007–2008,
more than two-thirds of PM2.5 samples exceeded the national ambient air quality 24-h standard of
60 μg m−33. Most of the pollution is found to be in winters because of the atmospheric conditions
that are found to be more stable in winters.
Various types of pollutants and sources of pollution in Delhi:
Vehicles:
Nitrogen Dioxide is one of the main components of air pollution in Delhi. It has been analysed
that the main source of releasing Nitrogen Dioxide is road traffic or the vehicles that are running
of the roads of Delhi. Burning of fossil fuels is also one of the major causes that generate
Nitrogen Dioxide. The presence of Nitrogen Dioxide also leads to the development of other
pollutants such as ozone, acid rain, etc. in Urban areas, most of the pollution occurs because of
