The Air Quality Index (AQI) in Ballygunge, Kolkata, currently stands at 92, placing it in the “Moderate” category, as reported by the Central Pollution Control Board (CPCB). While this level isn’t hazardous, it raises concerns for vulnerable groups like children, the elderly, and those with respiratory conditions.
Understanding the AQI Scale
The AQI measures air pollution levels on a scale of 0 to 500, with lower values indicating cleaner air. An AQI of 92 falls in the “Moderate” range (51–100), meaning air quality is acceptable but may pose mild health risks to sensitive individuals.
Factors Behind Ballygunge’s AQI
Kolkata’s air quality is affected by vehicular emissions, industrial pollution, construction activities, and rapid urbanization. Weather conditions like low wind speed and high humidity can trap pollutants, worsening the AQI. Recent Diwali celebrations, despite restrictions on firecrackers, have also contributed to temporary spikes in particulate matter.
Health Impacts of Moderate AQI
Prolonged exposure to moderate air pollution can cause respiratory discomfort, especially for those with asthma or lung diseases. Symptoms like coughing, throat irritation, and shortness of breath may occur. Healthy individuals should also limit outdoor activities during peak pollution hours.
Steps Taken by Authorities
The West Bengal Pollution Control Board (WBPCB) is actively monitoring air quality and enforcing stricter emission norms. Initiatives include promoting public transport, cleaner fuels, and green technologies in industries to combat pollution.
How Residents Can Help
Citizens can take actionable steps to protect themselves and improve air quality:
1. Limit Outdoor Activities: Avoid prolonged exposure during peak pollution hours.
2. Use Masks: Wear N95 masks to filter harmful pollutants.
3. Promote Green Spaces: Plant trees and maintain indoor plants.
4. Opt for Public Transport: Reduce personal vehicle usage.
5. Stay Informed: Regularly check AQI updates.
The Road Ahead
The AQI of 92 in Ballygunge highlights the need for sustained efforts to address air pollution. Collaborative action between the government, private sector, and residents is essential for a healthier environment.
