What are the causes of air pollution in Delhi in points?
Delhi is the capital and commercial city of India. As the population
grows, so does the demand for modern luxury items.
Huge industrial plants have been set up to meet this huge
demand. As a result, the level of air
pollution in Delhi is slowly increasing.
These
toxic levels of air pollution are creating serious problems in Delhi and its
environs. This situation is getting worse day by day.
About 65 % of air pollution
in Delhi is due to local sources and this is the main reason for the very
low air quality in the national capital and its adjoining areas.
Huge amounts of pollutants also enter the air and cause air pollution from thermal power plants, dirty fuels and diesel generators.
There are about 14 areas in Delhi where the level of pollution is higher than the city average. These areas have high pollution due to burning of municipal solid waste and industrial waste.
According to survey of more than 1,600 cities around the world found that the air quality in Delhi, the capital of India, is one of the worst cities in the world.
A 2017 survey found that Delhi's air was twice as bad as
Beijing's.
It
is estimated that about 2 million people die every year in India due to airpollution. Data indicate that one in four
premature deaths in India is due to contamination.
According to the WHO, the death rate in India due to chronic respiratory diseases and asthma is the highest in the world.
In Delhi, air pollution damages
the lungs of about 22.2 million or 50 per cent of all children.
According to a study by the
Indian Ministry of Economics, vehicle emissions are responsible for about 41%,
dust 21.5% and industries 18% as sources of air pollution in India.
But what are the reasons behind this increasing air pollution in Delhi? The main causes
for air pollution in Delhi are
discussed below.
Air pollution in Delhi for grain burning
1. One of the main reasons for the increase in air pollution in Delhi is the burning of crops by farmers in the
neighboring states of Punjab, Haryana and Uttar Pradesh.
It has been found that straw burning in Punjab and Haryana causes
about 6-7% air pollution in Delhi.
One of the main reasons for the weak AQI in Delhi is the burning of
crops by farmers in neighboring states.
Farmers
burn the paddy left over from the previous crop to plant new crops.
With the onset of the new planting season, the paddy is burned on a
large scale and forms a thick layer of fog in the northern plains, including
the Delhi NCR.
About 35 million ton of paddy is burnt in this state every
year.
Air pollution in Delhi from carbon fuels
2. Another
major cause of air pollution in Delhi
is the huge number of vehicles in Delhi.
The huge number of vehicles emitting smoke, fog, traffic jams and
accompanying smoke has reached dangerous levels in the air of Delhi.
As a result, the air quality index has reached critical levels.
The Central Pollution Control Board and the National Environmental
Engineering
Research Institute has identified vehicle emissions as
major contributors to the increase in air
pollution in Delhi.
Air
pollution in Delhi at the beginning of winter
3. Weather conditions also make air quality index worse. As
winter begins, the air particles become heavier and denser.
The cold air stays close to the ground, so the infamous smog in Delhi
is created around the city scene and after the lack of strong winds locking up
the polluters.
Although seasonal changes have always caused some changes in air
quality, the presence of additional pollutants has made the situation worse.
From October to December the AQI of Delhi can be deadly
(401-500) or dangerous (500+) levels for a variety of reasons, including road dust, vehicle pollution, burning of straw and cold weather.
Air pollution in Delhi due to
Diwali
4.
Alok Utsav is a popular festival in India and Delhi during Diwali. But it has
also become a health hazard for citizen of Delhi.
Huge
smoke from fireworks increases the number of toxic metals in the air. Hence it
is also a cause of air pollution in
Delhi.
Heavy smoking means the metals can hang in the ambient environment for
a few days, further aggravating the air quality index and making Delhi’s air
breathing worse.
Infrastructure
and real estate construction
5. Growing population growth is another major cause of air pollution in Delhi. AQI is
declining in Delhi due to infrastructure and real estate construction in the
Delhi NCR region.
Fine dust from construction activities is considered a major
contributor to the toxic mixture of smoke.
Private housing associations, malls and commercial
establishments are moving towards additional use of diesel generator sets for
power backup.
These gensets are contributing large amounts of carbon to the air
every minute.
Other causes of air pollution in
Delhi
6. Low investment in public infrastructure is another cause
of air pollution in Delhi. Public
transport and infrastructural investment in India is low, which leads to
congested roads and hence air pollution.
7. Industrial pollution and waste disposal air pollution is
increasing and smoking in the air is increasing.
8. Despite the availability of public transport such as
metro and local buses, public transport is a major source of air pollution in Delhi.
Vehicle fumes and other gaseous emissions from exhausts
increase the presence of pollutants in the air and add to the risk of
pollution.
9. Besides, cremation,
aircrafts and medical incinerations, MSW burning hotel and restaurants etc are
also causes of air pollution in Delhi.
10. Delhi's
pollution problem is also due to animal husbandry, as farmer burn various
harmful particles from their states to other states.
11. About 80 % of the land used for agriculture is used for
agriculture, so the fauna can also be blamed for the air pollution problem in Delhi.
12. Other causes include wood burning fires, farm fires,
discharges from diesel generators, dust from construction sites, burning of
rubbish and illegal industrial action in Delhi.
