Kolkata Air Quality Dips Ahead of Festivals
7 Nov
Summary
- Kolkata's air quality stations show poor to moderate readings.
- Indiscriminate cracker use during festivals may worsen air.
- Winter's slower winds trap pollutants for longer periods.
As of November 7, 2026, Kolkata's air quality stations are reporting concerning levels, with none achieving 'good' or 'satisfactory' readings. Two stations in Jadavpur and Bidhannagar indicated 'poor' air quality, which can cause breathing discomfort with prolonged exposure. Moderate air quality was recorded at five other locations, potentially impacting those with pre-existing lung or heart conditions.
Green activists and scientists express apprehension that indiscriminate cracker usage during Kali Puja and Diwali will exacerbate the already deteriorating air. Winter's arrival, characterized by slower wind speeds and reduced rainfall, means pollutants will linger in the atmosphere for extended durations, amplifying health risks. Tailpipe emissions, dust, industrial activity, and construction also contribute significantly to the pollution load.
