AQI in very poor category, new restrictions implemented under Group-3

Due to change in wind direction and reduced speed in the capital Delhi, the air quality has once again reached a very poor condition. Due to this severe pollution, people are facing problems like difficulty in breathing and eye irritation. Increasing pollution along with cold has made the situation worse. On Monday, Delhi’s Air Quality Index (AQI) was recorded at 379, which falls in the very poor category.

Degradation of air quality: statistics and situation

Monday in Delhi AQI 379 Which compared to Sunday 84 points more Is. This is the highest recorded AQI this month. Apart from this, air quality remained in poor condition in other cities of Delhi-NCR also:

• Greater Noida: 358
• Ghaziabad: 324
• Noida: 323
• Gurugram: 291
• Faridabad: 194

slow wind speed Due to this, pollutants remain in the atmosphere for a longer time, which worsens the air quality. Wind speed on Monday only 6 kilometers per hour was, which by evening 4 kilometers per hour It’s done. Due to this, pollution particles condensed and the health of the air deteriorated further.

Hybrid mode implemented in schools

In view of the serious situation of air pollution, schools in Delhi, Gurugram, Faridabad, Ghaziabad and Gautam Buddha Nagar Hybrid mode of study till class 5 Will be operated in. This means that children will be able to study both online and offline.

Due to deterioration in air quality

1. Slow wind speed:
   • Due to reduced wind speed on Monday, the pollutant particles remained in the atmosphere.
2. The problem increased with increasing cold:
   • Due to drop in temperature, pollutant particles started settling downwards, due to which air pollution increased further.
3. Ventilation Index:
   • ventilation index only on monday 200 square meters Which is much lower than average. In the next 24 hours this 500 square meters Can reach.
4. Mixing Depth:
   • Mixing depth on Monday 600 meters doing.
