Pollution in Delhi: How Can It Be Controlled?

November 25, 2014

by Rumani Saikia Phukan

A perennial problem in India is pollution. According to the global Environment Performance Index (EPI) 2014, India has reached a rank of 155, slipped 32 ranks from the previous year, and it is disheartening to hear that Delhi, the national capital of the country, is being tagged as one of the most heavily polluted cities in the world. It is the world’s worst city for air pollution. Thus, today, one of the biggest threats to the welfare of the people of Delhi and the city as a whole is pollution of various types.

Classification of pollution in Delhi

  • Air pollution
  • Noise pollution
  • Water pollution
  • Domestic waste
  • Industrial waste
  • Vehicular pollution
  • Hospital waste
  • Solid waste etc.

Causes of pollution in Delhi

  • Growing population of the city. The pressure and haphazard growth of the population is deteriorating the environment.
  • There has been highly haphazard and unplanned development of industries and factories. Studies have revealed that only about 20% of the industrial units are set up in the approved industrial areas whereas the rest of them are in residential and commercial areas.
  • There has been a huge rise in the vehicular population, in spite of the metro railways, aggravating traffic congestion and increasing air and noise pollution. It has also been reported that the number of vehicles plying on the roads of Delhi is more than that of the three metropolitan cities of Mumbai, Kolkata and Chennai taken together.
  • There has also been an ever-increasing number of diesel vehicles plying on the roads, which are largely responsible for the air pollution.
  • It has been reported by the National Environmental Engineering Research Institute (NEERI) that everyday almost 8,000 m tonnes of solid waste is being generated in Delhi. Plus we also have the industrial hazardous and non-hazardous waste. On an average, everyday, the MCDs and the NDMC manage to clear about 5,000-5,500 m tonnes of garbage. This results in the accumulation of more and more garbage in the city.
  • There has been no proper technology or methods to treat solid, liquid, waste water, industrial and hospital wastes in the city.
  • There has been too much dependence on fossil fuels like coal-fired power plants, improper use of energy in buildings and the excessive use of biomass for cooking and heating, etc

Particulate matter for measuring pollution

One way of measuring pollution is by the measure of particulate matter. Particulate matter is basically 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. It is also known as particle pollution or PM.

Pollution in Delhi: Facts and figures

  • According to the Ambient Air Pollution (AAP) report for the year 2014, Delhi had PM 2.5 pollution levels, which is the highest in the world, followed by Beijing. This result was based on the monitoring of PM measurement of outdoor air pollution from almost 1,600 cities in 91 countries.
  • The highest concentration of PM 2.5 form of air pollution is supposed to be a very serious matter and can lead to respiratory diseases and other health problems like lung cancer.
  • According to the WHO, air pollution is the fifth largest killer in India.
  • Carbon monoxide (CO), a dangerous gas emission, is around 6,000 microgram per cubic metre in Delhi, which is much above the the safe level of 2,000 microgram per cubic metre.
  • The level of nitrogen dioxide (NO2) has also been increasing.
  • According to the Ministry of Earth Sciences, Delhi’s air quality index (AQI) is 121, which is described as “poor.” The AQI is an index for reporting daily air quality, about how clean or polluted the air is.

Government’s steps to control pollution in Delhi

  • There are mobile enforcement teams deployed at various locations for monitoring polluting vehicles and vehicles not having PUC certificates.
  • A Mass Rapid Transport System (MRTS) is being constructed with the aim of providing a non-polluting, useful and affordable rail-based mass rapid transit system for Delhi, integrated with other modes of transport.
  • With a view to reducing vehicular pollution, there has been a ban imposed on the plying of more than 15 years old commercial/transport vehicles, taxis and autos that run on conventional fuels, including diesel driven city buses.
  • There has also been tightening of mass emission standards for new vehicles.
  • The quality of the fuel being supplied in Delhi has been significantly improved over the years by the ban of selling leaded petrol, introduction of low sulphur diesel, reduction of sulphur and benzene content in petrol.
  • There has been regular placement of dustbins, purchase of additional front-end loaders, mechanical sweepers, dumper placers, tipper trucks, to collect and dispose of garbage.
  • Steps are taken to transform garbage into compost by developing new sanitary land-fill sites.
  • The Delhi Government has constituted a committee to implement the Bio-Medical Waste (management and handling) Rules, 1998.
  • The Delhi Degradable Plastic Bag (Manufacture, Sale and Usage) and Garbage (Control) Act 2000 has been enacted for banning the manufacture and use of plastic bags, etc.

It’s not that the Government is not taking steps to control pollution in Delhi. But we need proper and efficient implementation of plans and programmes and policies launched by the Government.

How can citizens of Delhi help in reducing pollution?

Pollution in Delhi is a perpetual problem which need to be looked upon as a serious issue not only by the Government but also by the citizens of the city.

  • One of the easiest ways is that there should be an efficient involvement of Resident Welfare Associations in various localities in collection, segregation of garbage from houses and the societies.
  • Citizens can take steps to covert the garbage into compost in their localities.
  • More and more trees must be planted in every locality.
  • Every individual should keep a proper check on the pollution level of their vehicles.
  • Making more use of CNG.
  • One of the best ways to control pollution is to manage wastes of all types in a proper manner.
  • Each and every citizen should abide by the 3Rs: Recycle, Reuse, Reduce.
  • More and more people should use bus and metro instead of cars and scooters, as they can carry a lot more people in one journey. Car pool is also a good option.
  • Controlling the use of energy and making use of electricity in an efficient manner.
  • One can also reduce water pollution by reducing the use of chemicals, cleaning agents, pesticides, herbicides, fertilizers etc.

It is the duty of every citizen to think in a broader perspective to control pollution. We really don’t want our future generations to live in an unhealthy environment in Delhi. We really don’t want our children or our elders to get into incessant coughing due to pollution. Like we say charity begins at home, I take a pledge to do what I can for my environment and protect it to the best I can. If each one of us takes a pledge to do our bit for our environment, I am sure Delhi will be a better place to live in. Even a small step counts…

Essay on a Pollution Problem

Environmental pollution is one of the main threats for our planet. Pollution destroys the living environment and endangers human existence on Earth. No doubt, the economy finds many benefits in technological development. However, toxic emissions due to the work of factories, transportation, construction sites pollute the environment substantially. As the environmental pollution is a broad topic consisting of many sub-issues, there may be many approaches to building the consistent pollution essay. For instance, the pollution essay may concentrate on the various types of pollution, like sound pollution (noise pollution), water pollution, air pollution, soil pollution etc. Each paragraph of the essay will describe the separate type of the environmental pollution. Another suggestion is writing the pollution essay that highlights the consequences of pollution problems including the global warming effect, natural resources extinction, health problems of people and animals, the destruction of natural ecosystems, etc. The essay may also describe the causes of the pollution problems. Each paragraph, then, will be dedicated to one of the five main causes: industrial and technological development, transportation, agricultural activities, trading activities, and residences of people. Once you have selected the issue for the essay, you may draft the outline and move on to the analysis of the research and literature. The statistical data and approaches to pollution examination transform and improve over the time. So it is significant that you base your essay on credible and up-to-date sources. You may also look online for the essay sample on the pollution topic. However, you are encouraged to perform the research and develop your own paper first. The essay sample may be used as a practical tool and the structural example to follow.

Pollution Essay Sample

The population of our planet is increasing constantly. The population growth, unfortunately, has many adverse effects, one of which is the pollution problems. Pollution is a process of contaminating the environment in a way that it becomes unsafe to use. The contamination usually occurs through the chemical substances; however is not limited to tangible effects. The pollution can also take the form of the light, sound (noise pollution), or heat. The effects of pollution are devastative. The report of the NGO Pure Earth suggests that one of the seven deaths occurs due to pollution. Another comparison shows that pollution kills 60% more people than malaria, HIV/AIDS and tuberculosis combined. In this light, it is important to explore the various types of pollution and its effects on the environment and human beings.

One of the pivotal issues nowadays is the water pollution. The enlargement of the population means more trash and garbage. The rubbish dumps decay and the toxic substances permeate the soil going to the rivers and oceans. Moreover, tons of garbage are thrown directly into the water. There are even special islands for garbage in the oceans.

Even though the technological development offers various approaches to garbage utilization, most of the poor countries do not utilize innovative technologies. Thus, pollution becomes the leading cause of death in underdeveloped low-income countries. Nevertheless, water is contaminated not only due to regular garbage utilization. The plants, factories and mills are the key pollutants of the water. The process water from factories goes to the rivers and seas in neighborhood areas. In some rivers, the water is contaminated to the critical level and is banned from using. The fish and living environment of natural ecosystems are contaminated by dangerous chemicals that causes either the death of the entire ecosystems or hurts the consumers of the contaminated products (seafood, fish, water, salt).

Additionally, water is polluted by pesticides and fertilizations used in agriculture. The devastating effects of water pollution may be decelerated by installing the water purification mechanisms at factories and plants. These efforts should be promoted and enhanced on the governmental level. Moreover, states should develop the global programs of the environment protection as the problem is not limited to a particular territory or state. It is a universal hazard that requires combined efforts.

Another big humanity’s challenge is air pollution. Air consists of nitrogen, oxygen, water vapor and inert gases. When the typical structure of air is altered, we can observe the effects of air pollution. The primary reason of air contamination is the effect of the burning fuels. The smoke floats in the air and most people breath it in. Further, it affects the health resulting in respiratory diseases, cancers and other problems. Another type of air pollutants are dangerous gases, such as sulfur dioxide, nitrogen oxides, carbon monoxide, and chemical vapors. Those gases undergo the reactions in the higher atmosphere layers and return to the surface in the form of the dangerous chemicals (acid rains) that ruin the living environment. Moreover, carbon dioxide and sulfur dioxide create the so-called “greenhouse effect” when the radiation is absorbed while the heat is prevented from escaping. It is a natural process.

However, the high concentration of the gases makes Earth warmer and affects the natural processes on the planet. Thus, air pollution is one of the contributors to the global warming.


One of the least discussed problems is sound pollution. People tend to underestimate this problem because it is not possible to smell, see or touch it. However, noise pollution also has negative effects on the environment and people. The research shows that many illnesses are connected to noise pollution, such as hearing loss, high blood pressure, coronary heart disease and speech interference. The industrial noises also affect the lives of animals. For example, whales’ navigation system breaks down due to the sounds of ships. Besides, the industrial noise makes wild species communicate louder which requires additional efforts and decreases their life spans.

The growth of population and technological progress have imprints on the ecological stage of Earth. The extraction of natural sources, work of factories and plants, and other products of human activity result in various environmental problems. The pollution of water, air and sound have extremely negative effects on our environment. The effects of the pollution include acid rains, detrimental diseases and illnesses of people and animals, and global warming. The environmental pollution is the global problem that calls for radical actions for environment protection and rehabilitation. More than that, the problem should be resolved on a global level by the united efforts of the global community.
