Delhi Chokes: Air Quality Hits 'Very Poor' Amid Winter Smog

Delhi is currently experiencing a sharp deterioration in air quality, with its AQI exceeding 300 and entering the 'very poor' classification. This alarming rise in pollution, driven by winter conditions, low wind speeds, and crop burning in neighboring states, has triggered Stage II of the Graded Response Action Plan (GRAP).

Authorities are implementing measures to control emissions from vehicles, industries, and dust. The situation is particularly concerning as Diwali, a major festival celebrated with fireworks, is approaching. Historically, Diwali celebrations have significantly worsened Delhi's air quality, and this year is no exception, raising health concerns for residents.

This annual pollution crisis is compounded by factors such as vehicle exhaust, industrial emissions, and the seasonal shift in weather patterns. Despite a relatively clean October, a recent storm was followed by north-westerly winds carrying smoke from burning fields, leading to the current smog. The Supreme Court has allowed limited use of certified green firecrackers during specific hours on November 7 and 8, and banned them near sensitive zones.

While Delhi grapples with this crisis, Mumbai has also seen elevated pollution levels, though its air quality has improved recently. The reliance on green firecrackers and the challenge of enforcing bans remain critical issues in mitigating the severe air pollution episodes in Indian cities.
