New Delhi | Jagran News Desk: A day after people celebrated Diwali, the air quality in Delhi-NCR deteriorated to ‘severe’ category. According to the Air Quality Index (AQI) data, major pollutant PM 2.5 was recorded at 500 in Lodhi road, Delhi which falls in the severe category. However, the situation was still better than the last three years, according to government agencies.

This comes after the System of Air Quality and Weather Forecasting And Research (SAFAR) predicted that the air quality in the national capital will get even worse in coming days and the AQI was expected to be around 324 due to Diwali.

Here’s everything you need to know about AQI in Delhi:

1. The AQI on Monday morning was recorded at 500 in Delhi which falls in the severe category.

2. While on Sunday evening, the pollution entered the ‘hazardous’ zone after the AQI was recorded at 763, the highest, at the National Malaria Institute in Dwarka (West Delhi); 407 at the ITI Jahangirpuri (North Delhi), 313 at Shrinivaspuri (South Delhi).

3. In Chanakyapuri, where the US embassy is located, the AQI was 189 and at the Jawahar Lal Nehru Stadium, 168 at 8 pm. At no place, the AQI monitors showed less than 100.

4. An AQI between 0 and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.

5. According to SAFAR, the pollution level is expected to worsen in the coming week because of the emission from firecrackers and stubble burning in adjoining areas of the NCR. Meanwhile, a thin layer of haze is already hanging over Delhi.

6. “If 50 per cent of the total load of firecrackers (average of Diwali 2017 and 2018) is added, the AQI may plunge to the severe category for a short period,” the SAFAR had said earlier.

7. Meanwhile, stubble burning in Punjab and Haryana makes the situation worse in Delhi-NCR. According to Punjab Remote Sensing Centre (PRSC), straw burning has increased this year.

8. To curb air pollution, the Aam Aadmi Party (AAP) government in Delhi has announced the implementation of the Odd-Even scheme from November 4 to 15. They also launched laser light shows to discourage residents from bursting firecrackers and to encourage them to celebrate Diwali with lights and music.
