1. About 31 areas in Delhi recorded 'very poor' air quality while two areas showed 'severe' air quality levels. CRRU Mathura Road and Dwarka Sector 8 witnessed 'severe' level of pollution at 414 and 402, respectively, the data said. Anand Vihar, DTU, Mundka, Narela, Nehru Nagar and Rohini all showed 'very poor' air quality, it added.
2. 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".
3. On Wednesday and Thursday, the air quality had deteriorated to the 'very poor' category, alarming authorities who were planning to roll out more stringent measures to combat pollution. The air quality temporarily improved on Friday after rainfall, but it worsened again.

Here are some tips to fight Delhi's nasty pollution
- Get yourself a mask and use that always. According to medical experts, the most effective masks are N95 and N99 pollution masks.
- Try and stay indoors as much as possible. Grow indoor plants to clean air naturally. But an air purifier is needed.
- Try doing exercises and work from home and going out can make you fall sick.
- Wear full sleeve clothes and full pants as the pollution can irritate your skin too.
- Instead of brooming, pour water around your house to keep the dust settled. Also clean your house regularly.
