The air quality in Ballygunge, a bustling residential and commercial hub in Kolkata, has become a growing concern for residents and environmentalists. As of today, the Air Quality Index (AQI) in Ballygunge is 89, classified as “Moderate” by the Central Pollution Control Board (CPCB). While this is better than the hazardous levels in some regions, it still raises questions about long-term health and environmental impacts.
Understanding the AQI Scale
The AQI measures pollutants like PM2.5, PM10, NO2, SO2, CO, and O3. It categorizes air quality as:
– 0–50: Good
– 51–100: Moderate
– 101–200: Unhealthy
– 201–300: Very Unhealthy
– Above 300: Hazardous
With Ballygunge’s AQI at 89, the air quality is acceptable but may pose moderate health risks for sensitive individuals, such as children, the elderly, and those with respiratory or cardiovascular conditions.
Factors Affecting Ballygunge’s Air Quality
Several factors contribute to the AQI in Ballygunge:
1. Vehicular Emissions: Increasing traffic from cars, buses, and two-wheelers.
2. Construction Activities: Rising dust and particulate matter from ongoing projects.
3. Industrial Influence: Proximity to industrial zones and the Hooghly River.
4. Seasonal Changes: Winter temperature inversions trap pollutants closer to the ground.
Health Risks of Moderate AQI
An AQI of 89 can cause mild respiratory discomfort, eye irritation, throat discomfort, and fatigue, especially for sensitive groups. Experts recommend:
– Limiting outdoor activities during peak pollution hours.
– Using air purifiers indoors.
– Wearing N95 masks to reduce pollutant inhalation.
Steps to Improve Air Quality
The West Bengal Pollution Control Board (WBPCB) has implemented measures like stricter vehicle emission norms and public awareness campaigns. Residents can also contribute by:
– Carpooling or using public transport.
– Planting trees and supporting green initiatives.
– Reducing waste and adopting sustainable practices.
The Road Ahead
While the AQI of 89 highlights the ongoing challenge of air pollution, it also underscores the need for collective action. By balancing development with environmental sustainability, Kolkata can ensure cleaner air for future generations.
