A recent report by the prestigious medical journal The Lancet has labeled Bihar as a ‘pollution trap,’ raising serious health concerns for the state’s population. Released on Friday, January 23, 2026, the report highlights that the entire population of Bihar is exposed to air quality that is several times worse than the safety limits set by the World Health Organization (WHO). The high levels of PM2.5 in the air are now being considered a major public health crisis.
Health Risks Predicted for Next Two Years
The study predicts a worrying surge in critical health conditions over the next 12 to 24 months. By early 2028, hospitals across the state may see a significant rise in cases of heart attacks, brain strokes, and lung cancer. The fine particulate matter causes inflammation in the body, leading to artery blockages. The report also notes that non-smokers are increasingly at risk of developing lung cancer due to persistent exposure to toxic air.
Worst Affected Cities in Gangetic Plain
The report identifies specific cities situated in the Gangetic plain as the worst affected zones. Persistent fine particulate matter has been recorded in these urban centers, making them highly unsafe without proper protection.
| City | Key Issue |
|---|---|
| Patna | Severe PM2.5 Levels |
| Muzaffarpur | Persistent Pollution |
| Gaya | Above Safety Limits |
| Purnia | High Exposure Risk |
Call for Medical Emergency Declaration
Experts suggest that the government should consider declaring a medical emergency to tackle this invisible killer. The pollution is also linked to the growth of superbugs, which are resistant to standard medicines. While the Bihar State Pollution Control Board (BSPCB) enforces the Graded Response Action Plan (GRAP), 20 out of 24 monitored cities still exceed national pollution standards.
Precautions for Common Public
Health experts have recommended the use of N95 masks for daily commuters. It is advised to avoid outdoor activities like walking or running if the Air Quality Index (AQI) crosses the 200 mark. The report emphasizes that immediate steps are needed to prevent the looming health crisis predicted for the coming years.
