Delhi’s Air Quality Turns ‘Very Poor’ as Fog and Calm Winds Trap Pollution

Delhi: Air quality in Delhi reached a "very poor" level on Sunday morning, with AQI recorded above 400 in many areas. Due to light fog and slow wind, pollutant particles remained trapped in the atmosphere. Experts have warned that the situation will persist for the next few days and advised people to take precautions.

What happened—why did Delhi's air suddenly become bad?

Delhi's air reached the 'very poor' category on Sunday morning—the city-wide AQI crossed 370 in the morning, which is a respiratory concern. Experts say that dense fog and low wind speed are keeping the pollutants stuck near the ground; hence, the process of cleaning has come to a halt. 

Which areas are most affected?

According to multiple reports, AQI reached above 400 in areas like Wazirpur and RK Puram—readings that fall in the 'severe' category. Many more in the range of 300-400 were seen in different parts of the city.

Did the weather make it worse?

Shallow fog and low wind speed in the morning prevented the dispersion of particles. Besides, smoke rising from neighboring states and particles from the burning of stubble in the fields are also believed to have made some contribution, which worsened the overall situation. Meteorological and air-quality models have suggested the same reason. 

How long can this situation last, and what warnings have been given?

According to central agencies and weather models, the wind may remain slow for the next 2-3 days, so there is little hope of a quick improvement; some agencies have also predicted the air quality to remain 'very poor.' Officials have advised people in sensitive categories to exercise caution.

What precautions are necessary for the general public?

Everyone is suffering from respiratory diseases, whether they are children, youth, or old. One should avoid unnecessary going out. If you have to go out, wear a good-quality mask and limit vigorous exertion or exercise, and it would be better to keep an air purifier at home or at least keep the internal doors and windows closed.
