Air pollution is an important risk factor

Air
pollution is an important risk factor for not just human but also to other
living organisms. As population of a country grow level of pollution
increases as well. The rapid growth in motor
vehicles and industrialization is causing the air to be more polluted. However,
air pollution is more common in the cities of developing countries, Delhi,
India being one of them. This essay will describe what is causing the air in
Delhi to be more polluted and how government or private individuals had done to
reduce this air pollution in the capital city of India. Firstly, this essay
will discuss about causes of the air pollution in Delhi. Then damage of
vehicles with motor will be evaluated. In the final part, Delhi’s power plants
and energy resource related crisis also will be evaluated.

 

 

 

There
are many causes of air pollution and there are few main reasons Delhi, India
being the most polluted city in the world. It is true that most of its air
pollutions is caused by industry and followed by unclean engines from motor powered vehicles, especially
diesel-powered city buses and trucks. The emission of gases from
these into the air causes what is known as smog. Smog consists of tiny
particles also known as particle matter (PM) in the air includes a
mixture of solids and liquid droplets (Online dictionary 2017). One way of measuring pollution is
by the measure of particulate matter. Particulate matter is a mixture of
extremely small particles and liquid droplets like acids, chemicals, gas,
water, metals, soil dust particles, etc., the measurement of which gives an
idea of the pollution of a city. According to Department of Environment, Delhi there
are 2 major reason for hazardous level of pollutants in Delhi 1) Vehicles: from 2002 to 2012, vehicle numbers have increased by as much as 97%,
contributing enormously to the pollution load and direct exposure to toxic
fumes. 2)
 Industries and thermal power plants make up 29
percent of the total air pollution in Delhi. Because coal is the most abundant
fossil fuel in India
90%
of Delhi is powered by coals other 10% includes diesel, gas, renewable energy
etc. Singh et al. (2010, pp 685-689).  Also,
India has poor quality coals which have high ash content (35-45%) Singh et al
(cited in Mathur et al., 2003). Burning
of bad quality coal emits greater amount of carbon monoxide, hydrocarbon,
nitrogen oxides, and particulate matter. Due to very fine particle size
and presence of potentially toxic elements like Arsenic, Chromium, Boron,
Vanadium and Antimony Rai et al. (2004, pp. 293-300). These tiny particles are
known to be toxic for living organisms. Some heavy metals could contaminate
near waters, ground water, and surrounding soil Rai et al. (2004, pp. 293-300).

This makes pollutants more hazardous for citizen of Delhi.

 

 

In
the recent years government of Delhi has taken measurements against the
pollution of the city. Since, pollution created by the motor vehicles are high
making this problem priority is important. Recently, government of Delhi
launched a campaign to raise awareness to citizens of Delhi about air pollution
and educate
motorists about the health hazards also to show importance of engine tuning and
maintenance (government of Delhi 2017). Mass Rapid Transport System is being
constructed with the idea to create a non-polluting, efficient and affordable
rail based fast massive transit system (government of Delhi 2017). Improvement
in fuel quality has been significantly improved during recent years by
completely removing leaded petrol, reducing Sulphur content in diesel fuel, and
the quality of petrol being supplied to Delhi has been improved further by
reduction of Sulphur content to 0.015% & Benzene Content to 1% (government
of Delhi 2017). Furthermore, instead of replacing old vehicles or diesel
vehicles having alternate fuel might be more beneficial. LPG (Liquefied
Petroleum Gas) is better alternate automotive fuel due to its clean combustion
and better drive-ability compared to both conventional fuels (government of
Delhi 2017). The vehicle running on petrol can easily be convertible and
converted vehicle can have both the option of using LPG& petrol fuel
(government of Delhi 2017).
