Ballygunge’s Air Quality Reaches Unhealthy Levels (AQI 175)
The Air Quality Index (AQI) in Ballygunge, Kolkata, has risen to 175, marking it as “unhealthy” per CPCB data. This spike alarms residents and health experts, urging immediate attention to pollution sources and mitigation strategies.
What Does an AQI of 175 Mean?
The AQI measures air pollution severity on a 0–500 scale. At 175:
– Health Impact: Sensitive groups (children, elderly, asthma patients) face higher risks. Symptoms include coughing, throat irritation, and worsened lung conditions.
– General Population: Prolonged exposure may reduce lung function and increase cardiovascular stress.
Top 5 Causes of Poor Air Quality in Ballygunge
- Traffic Emissions: Kolkata’s congested roads, especially older vehicles, spike NO₂ and PM2.5 levels.
- Construction Dust: Ongoing projects release PM10 and PM2.5, major contributors to the AQI surge.
- Industrial Pollution: Nearby factories and brick kilns emit sulfur dioxide (SO₂) and particulate matter.
- Weather Trapping Pollutants: Low wind and high humidity prevent pollutant dispersion.
- Waste Burning: Open burning of garbage and crop residue worsens urban air quality.
Health Risks: Expert Warnings
Dr. Priya Banerjee, a Kolkata pulmonologist, states:
“An AQI of 175 can trigger asthma attacks, eye irritation, and long-term respiratory damage. Vulnerable groups should stay indoors during peak hours.”
Residents report increased mask usage, echoing pandemic-era precautions.
Government Actions & Gaps
- WBPCB Advisories: Recommends reduced outdoor activity, especially mornings/evenings.
- KMC Measures: Road sprinkling and mechanical sweeping to curb dust.
- Criticism: Activists demand stricter vehicle emissions checks and waste management reforms.
How Ballygunge Residents Can Stay Safe
- Track Real-Time AQI: Use CPCB’s portal or SAFAR app.
- Limit Outdoor Exercise: Avoid jogging/walking when AQI exceeds 150.
- Use N95 Masks: Effective against PM2.5 during commutes.
- Indoor Air Purifiers: HEPA filters reduce indoor pollution.
- Eco-Friendly Commutes: Carpool, use public transport, or cycle.
Long-Term Solutions Needed
To combat Kolkata’s air crisis, experts advocate:
– Phasing out old vehicles.
– Expanding urban green spaces.
– Stricter industrial emission controls.
With winter approaching (typically high-pollution season), proactive measures are critical.
