Air Pollution Control

The image given below shows the resulting air pollution caused by the burning of fossil fuels, emissions from industries and automobiles, burning of fossil fuels and lot more practices which disturbs the quality of air.

You can actually see the clouds of smoke caused because of more pollutants present in the air. The image was captured by NASA satellites in the year 2013.

Air Pollution & Its Control

Did you know that India has the highest rate of deaths due to respiratory diseases? According to a study in the year 2013, non-smokers in India have a 30% higher impaired lung function compared to Europeans.

Why the difference? The answer is obvious –‘The quality of air’. So what are the causes of air pollution in India?

Air Pollution Causes

The major causes of air pollution in India are:

  • Industrial emissions.
  • Exhaust emission from vehicles.
  • Congested traffic in almost all cities of India.
  • Using crude means of producing fuel like burning firewood and biomass.
  • Use of adulterated fuel leading to unburnt or partially burnt particles contributing to air pollution.
  • According to India’s National Health profile of 2015, there has been an exponential rise in diseases and allergies caused due to air pollution in the past 15 years, even considering the rising population.

According to the physicians, environmentalist and other medical specialists, most of the citizens of Delhi and other parts of India like Mumbai, Bangalore may never recover from their lung disorder owing to the extremely bad quality of air available. The quality of air exceeds the safe limits set by many times. The effects of air pollution can also be seen to affect the famous monuments of our country such as the Taj Mahal in Agra, Mysore Palace in Mysore, Hawa Mahal, in Jaipur, Qutub Minar, Delhi, the Golden Temple in Amritsar and lot more.

How to Control Air Pollution?

So how can air pollution be controlled or reduced?

Given below are a few measures on how to control air pollution.

  1. By minimizing and reducing the use of fire and its products.
  2. Since industrial emissions are one of the major causes of air pollution, the pollutants can be controlled or treated at the source itself to reduce its effects. For example, if the reactions of a certain raw material yield a pollutant, then the raw materials can be substituted for other less polluting ones.
  3. Fuel substitution is another way of controlling air pollution. In many parts of India, petrol and diesel are being replaced by CNG – Compressed Natural Gas fuelled vehicles. These are mostly adopted by vehicles that aren’t fully operating with ideal emission engines.
  4. Although there are many acts in place in India which focus on repairing the quality of air, most of them are either forgotten or not being enforced properly. There are still a lot of vehicles on roads which haven’t been tested for vehicle emissions.
  5. Another way of controlling air pollution caused by industries is to modify and maintain existing equipment such that pollutants are minimized.
  6. Sometimes controlling pollutants at the source is not possible. In that case, we can have process control equipment to control the pollution.

Here is a flowchart which provides an in detail explanation about the equipment to control the pollution.

Air Pollution & Its Control

  1. A very effective way of controlling air pollution is by diluting air pollutants. If they diffuse with a large area of clean air, the natural process of cleaning would come into play and the polluting effects themselves will be reversed. Especially in industries, the use of tall chimneys can serve this purpose. The pollutants will disperse in heights large enough such that the ill effects can be minimized to a large extent.
  2. The last and the best way of reducing the ill effects of air pollution, in the long run, is through vegetation. Plants and trees reduce the pollutants in the air to the maximum amount. Ideally, plants in areas of high pollution will be extremely effective. Hence plant more trees to protect our planet from air pollution.

These were a few important points, information and actions which can be taken to control and reduce Air pollution.

By following these simple steps, we can protect our planet earth and also help those patients to recover from different types of lungs diseases including asthma and other Respiratory System Disorders.
