Delhi's air quality is continuously worsening after Diwali, possibility of ban on passenger buses!

After Diwali, the climate of the national capital Delhi continues to remain in poor category. Even on Thursday morning the sky is wrapped in a blanket of fog.

This fog is becoming denser. Due to which visibility has reduced significantly and it has become difficult to see beyond a few 100 meters. Dense poisonous smog has returned to Delhi, Noida, Gurugram and surrounding places on Thursday morning.

The air quality index 24 hours ago, was 401, whereas 397 was recorded on Thursday.

According to Central Pollution Control Board (CPCB) data, Patna's air quality fell into 'hazardous' category after Delhi, with its AQI being 587 at 6.30 am today, while Delhi's AQI was 449 at 6.30 am on Thursday.

As of 6:30 am today, in the list of top 10 polluted cities with highest air quality index, two are in Bihar, more than three are in Rajasthan, apart from Delhi, Punjab, Haryana and other cities.

In view of the pollution situation, the Delhi government can impose a complete ban on the entry of all passenger buses into the national capital except those running on CNG, electricity and BS-6 diesel. Restrictions under GRAP Phase IV remain in place in Delhi amid worsening air quality in the national capital.

Delhi has been covered with thick blanket of smog for the past several days. Light rains before Diwali improved the air quality but large scale fireworks on Diwali once again worsened the air quality. Though there was ban on bursting firecrackers by the Supreme Court, it was flouted blatantly resulting in a sharp rise in the air pollution.
