Ballygunge’s Air Quality Reaches Unhealthy Levels (AQI 156)
The Air Quality Index (AQI) in Ballygunge, Kolkata, has surged to 156, landing it in the “unhealthy” category per the Central Pollution Control Board (CPCB). This spike has alarmed residents and health experts, spotlighting the urgent need for pollution control measures.
What Does an AQI of 156 Mean?
The AQI scale categorizes air pollution’s health impacts:
– 0-50 (Good): Safe for all.
– 51-100 (Moderate): Mild risk for sensitive groups.
– 101-150 (Unhealthy for Sensitive Groups): Children, elderly, and asthma patients advised caution.
– 151-200 (Unhealthy): Everyone may experience symptoms like coughing or shortness of breath.
– 201+ (Very Unhealthy/Hazardous): Severe health warnings.
At 156, Ballygunge’s air poses risks to all, especially vulnerable populations.
Why Is Ballygunge’s Air Quality Poor?
Key contributors include:
1. Traffic Pollution: Peak-hour congestion emits PM2.5 and NO₂.
2. Construction Dust: Ongoing projects elevate particulate levels.
3. Industrial Emissions: Nearby factories release pollutants.
4. Weather: Winter inversions trap smog.
5. Local Burning: Waste/biomass burning worsens PM2.5.
Health Risks of Prolonged Exposure
Dr. Priya Chatterjee, a Kolkata pulmonologist, notes: “AQI 156 can aggravate asthma, COPD, and cause lung irritation. Long-term exposure raises risks of heart disease and infections.”
How to Stay Safe
- Reduce outdoor activity, especially during peak pollution hours (7–10 AM, 6–9 PM).
- Wear N95 masks outdoors.
- Use air purifiers with HEPA filters indoors.
- Track real-time AQI via CPCB or SAFAR-Air apps.
Long-Term Solutions Needed
Advocates demand:
– Stricter vehicle/industrial emission checks.
– Expanded public transit (metro, e-buses).
– Dust suppression at construction sites.
– Tree planting drives to absorb pollutants.
Key Takeaway
Ballygunge’s unhealthy AQI underscores Kolkata’s growing air crisis. Individual precautions help, but systemic action is critical. Stay informed via NextMinuteNews for updates.
