New Delhi: Air pollution in Delhi has become a common condition for the past few years with the onset of winters. The air quality in the national capital has turned critical after Diwali due to smog, dust, air pollution and smoke.
People start having trouble in breathing and the bad air in the environment worsens the health of people with comorbidities.
The increase in pollution in Delhi is partly due to stubble burning in neighboring states including Punjab, Haryana, Uttar Pradesh. Visibility also gets worse due to air pollution in Delhi-NCR (National Capital Region).
However, smoke from crop fires is not the only contributor to foggy skies. Dust influx sometimes comes from the Thar Desert to the west, while cities also have a host of other human-caused sources of air pollution, including motor vehicle smoke, industrial and construction activity, fireworks, and fires for heating and cooking. Contains particulate matter and other pollutants.
A satellite image by NASA (National Aeronautics and Space Administration) shows a river of smoke moving towards Delhi from fires in Punjab and Haryana.
Stubble burning is the process where farmers get rid of crop residues by setting fire to make room for a new batch of crops. This annual activity leads to the recurrence of seasonal pollution.
The level of air pollution has not increased much since the beginning of November this year, due to sluggish monsoon. But, after the last fortnight of the second week of November, the fire activities gained momentum.
Due to drop in mercury levels and lack of winds, pollutants get trapped in the atmosphere for longer than usual. This makes Delhi’s air quality dangerous for everyone, even a healthy person.
For the past few days, almost every morning in Delhi, commuters have been traveling amidst dense fog. Visibility is low, making it difficult for people.
To reduce the impact of air pollution, people in Delhi are wearing face masks whenever they step out. Many people are complaining of shortness of breath even after breathing in the open air.
An aerial view shows how Delhi air pollution has intensified since early November. Visibility remains poor and there is an indication of poor air quality.
The historic Humayun’s Tomb in the national capital was recently engulfed in thick fog.
Air pollution and smog is increasing in Delhi. In the national capital, people are awake for most of the morning in a hazy atmosphere. The Red Fort has also been hit by smog.
Low visibility due to smog and pollution in the national capital leads to cancellations as well as delays of flights and trains. The situation has remained the same during October-December for the last few years.
In the neighboring state of Uttar Pradesh, in Agra, the iconic Taj Mahal can be seen drenched in smog following a rise in air pollution.
The Arvind Kejriwal-led government in Delhi is using anti-smog guns to curb air pollution. Now, this anti-smog gun sprays atomized water to settle dust and other suspended particles in the atmosphere.
Meanwhile, the System of Air Quality and Weather Forecasting and Research (SAFAR) has forecast Delhi’s air quality to be in the ‘very poor’ category for Friday and again to ‘severe’ in the next few days.
It has also said that local surface winds for the next three days (Friday, Saturday and Sunday) are relatively low which reduces the dispersion of pollutants leading to deterioration in air quality but falls in the ‘upper end of very poor’ category. within.
On November 29, the local surface winds are likely to increase resulting in an improvement in the air quality but it will remain in the ‘very poor’ category. Local emissions and weather are likely to be major factors controlling air quality. ,photo credit: NASA, ANI,
