Causes of Air pollution in Delhi
Burning of crops
The primary cause of air pollution is the burning of crops by the farmers from the neighbouring states of Haryana and Uttar Pradesh. Farmers burn rice stubbles at the end of the Kharif season before commencing the planting of crops for the Rabi season.
The wind directs the smoke towards Delhi and worsens the already polluted atmospheric air. The smog in Delhi traps the pollutants and dust particles and makes it difficult to breathe.
Delhi has a high number of environmentally friendly CNG-run buses. In spite of this, the air pollution due to vehicular emission is tremendous. It is because of the reduced green cover over Delhi. The past two decades have seen a rampant growth of real estate all over the city.
The onset of winter
The air becomes stagnant at the beginning of winter. The dust particles get trapped in the cold and damp air thereby affecting weather conditions. It results in the development of smog all over the area. It reduces visibility to a great extent. As a result, there were numerous vehicular accidents on the highways.
Growth in population
Of late, New Delhi has become an overpopulated city. Naturally, it adds to noise as well as air pollution.
Lack of public infrastructure
India has a reputation for investing less in public means of transport. It makes people resort to bringing out their private cars on the roads. It causes unnecessary congestion of traffic thereby contributing to the increase in pollution levels.
The NCR and its neighbourhood has seen tremendous construction activity in recent times. As it is, the quality of outdoor air is pure. The rampant increase in the construction activity adds to the problems.
It is a collective malaise in many cities in India. The release of industrial wastes into the air and water is one of the primary reasons for air pollution. Dumping and burning of garbage contribute broadly as well.
The Delhi Government did its best to curb air pollution by banning cracker sales. However, religious fervour saw people bursting crackers and worsening the already polluted air.
The magnitude of Air Pollution in Delhi
The AQI index showed a reading of 999 whereas anything over 300 is considered hazardous.
The smog affected visibility levels to such an extent that the Indian Railways cancelled or diverted several trains passing through Delhi. Similarly, there were frequent flight cancellations and delays due to poor visibility conditions.
The pile-up of cars on the national highways was tremendous.
The Chief Minister of Delhi compared the city to a gas chamber stating that this was a common problem every year. The Government ordered the closure of schools and educational institutions as a remedial measure. There was a tremendous increase in the level of patients complaining of acute respiratory problems in the capital.
The US State Department has its air quality monitoring stations in India. It took the extreme step of installing air purifiers in the offices as well as the homes of their staff members. It was tough for people to breathe properly.
Medical experts likened the pollution levels to be equal to smoking 50 cigarettes a day. Hospitals in Delhi declared a state of public health emergency.
The quality of air was so bad that it nearly resulted in the abandonment of a cricket Test Match. It was the first instance of play being help up or suspended due to pollution. Players from both the Indian as well as the Sri Lankan cricket teams found it difficult to continue playing.

Effects of Smog
Steps to Control the Smog
The Delhi Government was in a quandary. They had to face such an unprecedented situation. The Government started blaming the neighbouring states for burning crops and causing air pollution in Delhi.
However, burning of crops is common all over the country. The situation in Delhi was such that the position was already dangerous. The burning of plants and the onset of winter coincided to create this worst situation.
The National Disaster Management Authority (NDMA) issues firm guidelines for people to follow and protect themselves against the hazardous impact of air pollution and smog.
- Do not step outside the house, especially in the early morning when the smog is at its worst.
- In case you have to move outdoors, do so after the sun starts shining brightly.
- Seek medical help if you experience breathing problems.
- Ensure that children remain indoors at all times
- The situation is already dangerous. Do not make it worse by smoking cigarettes or burning garbage.
- Drink lots of water to flush out the toxins from the body.
- Avoid doing strenuous activities as it can cause you to inhale deeply. It can worsen the situation.
- Eat fruits having lots of Vitamin C, magnesium, and omega fatty acids.
- Encourage use of nasal filters to get short-term relief.
- Install air purifiers in your homes and offices.
- Have air purifying plants like aloe vera and English Ivy in your house.
- Avoid going out on the main roads as vehicular pollution can make matters worse.
- Refrain from venturing into areas with heavy smoke or dust.
The worst is not over. If Delhi does not take enough steps to reduce air pollution, such a situation can come again. The same situation can occur in other cities as well.
The best way to fight air pollution is to plant enough trees and restore the green cover. Use environmentally friendly fuels for your vehicles as well as for cooking.
