Ballygunge’s Air Quality Index (AQI): Current Status
The Air Quality Index (AQI) in Ballygunge, Kolkata, stands at 91, placing it in the “Moderate” category. While this is better than many Indian cities battling severe pollution, sustained exposure may affect sensitive groups. Here’s a detailed look at what this means for locals.
What Does AQI 91 Mean?
The AQI measures air pollution from 0 (Good) to 500 (Hazardous). Key categories:
– 0–50 (Good): Safe for all.
– 51–100 (Moderate): Mild risk for sensitive individuals (asthma, elderly, children).
– 101+ (Unhealthy): Rising health risks.
At 91, Ballygunge’s air is acceptable but not ideal—prolonged exposure could aggravate respiratory or heart conditions.
Top Pollution Sources in Ballygunge
- Traffic Emissions: Major roads (Gariahat, Rashbehari Ave) emit NO₂ and PM2.5 from vehicles.
- Construction Dust: High-rise projects and infrastructure work release particulate matter.
- Waste Burning: Occasional garbage/leaf burning worsens air quality.
- Weather Traps Pollutants: Kolkata’s humidity and low wind speed prevent pollution dispersion.
Health Risks at AQI 91
- Short-term: Coughing, throat irritation, asthma flare-ups.
- Long-term: Reduced lung function, higher cardiovascular strain.
Sensitive groups (children, elderly, chronic illness patients) should take extra precautions.
5 Ways to Stay Safe
- Track AQI daily via apps like AQI India or SAFAR.
- Reduce outdoor exercise during peak pollution hours (mornings/evenings).
- Wear N95 masks in heavy traffic zones.
- Use air purifiers with HEPA filters indoors.
- Support green initiatives (carpooling, tree planting, reporting waste burning).
Government Actions & Challenges
The West Bengal Pollution Control Board (WBPCB) enforces:
– Stricter vehicle emissions testing.
– Construction dust control (water sprinkling mandates).
– Public awareness campaigns for cleaner air.
However, inconsistent enforcement requires community vigilance for lasting impact.
Kolkata’s Seasonal Air Quality Trends
Ballygunge fares better than industrial zones (e.g., Howrah), but winter (Nov–Feb) sees higher AQI due to:
– Festival fireworks.
– Temperature inversions trapping smog.
Key Takeaways
- AQI 91 = Moderate risk. Stay alert but not alarmed.
- Protect vulnerable groups with masks and indoor air filters.
- Advocate for stricter policies to curb traffic and construction pollution.
“Clean air starts with awareness—monitor, adapt, and act.”
