Patna: The festive glow of Diwali has been replaced by a dense shroud of smoke and haze across Bihar, signaling a severe post-celebration air quality crisis. Cities from Patna to Gaya, Bhagalpur, and Darbhanga reported thick smog settling over the landscape on Tuesday morning, a direct consequence of intense late-night fireworks.
The combined effect of particulate emissions and unfavorable weather conditions has created layers of toxic air that refuse to disperse, leading to widespread reports of stinging eyes and sore throats across the major urban centers.
AQI in the Danger Zone
The state’s Air Quality Index (AQI) has soared to alarming levels. Key monitoring stations in Patna, Gaya, Bhagalpur, and Darbhanga recorded AQI readings between 150 and 300, classifying the air quality as “moderate to poor.”
Health experts have voiced serious concern over these figures, cautioning that pollution at this level is particularly dangerous for the state’s vulnerable residents, including children, the elderly, and individuals with respiratory conditions like asthma. They have advised the public to minimize outdoor activity, especially morning walks, until the air clears.
Meteorological Traps
The Patna Meteorological Center reports that high pollution is being exacerbated by stagnant weather patterns. Temperatures across the state are running 2-3 degrees Celsius above normal, contributing to the problem.
On the morning of October 21, Patna recorded a minimum temperature of 24.7°C and a maximum of 33.8°C. Crucially, wind speeds were reported at a sluggish 2 to 3 kilometers per hour. These low wind speeds are insufficient to sweep the fine particulate matter out of the city, effectively trapping the dust and smoke near the ground.
Hope Hinges on Bay of Bengal System
While the current conditions are severe, the India Meteorological Department (IMD), Patna offers a glimmer of hope. According to their latest forecast, a new low-pressure area developing over the Bay of Bengal is anticipated to bring relief.
IMD officials stated that this system is expected to induce light to moderate rain across many districts of Bihar around October 25. The rainfall is crucial, as it will naturally cleanse the atmosphere, forcing the fine, trapped particles to settle and significantly improving the air quality index and overall visibility. The rains are also predicted to bring down the elevated temperatures, making the weather more pleasant.
Public Advisory Issued
In the face of the ongoing smog crisis, authorities are appealing to citizens for cooperation. The Patna Municipal Corporation and the Bihar State Pollution Control Board have urged residents to avoid unnecessary use of vehicles and refrain from burning garbage in the open, actions that further contribute to the toxic air burden.
Health experts strongly recommend the increased use of air purifiers or indoor plants within homes, and advise children and the elderly against prolonged outdoor exposure over the next few days.
