Despite a Supreme Court order banning firecrackers, the aftermath of Diwali celebrations revealed a spike in air pollution levels in major cities across India. In Delhi, where intermittent noise of firecrackers persisted, residents woke up to a thick haze, with the air quality index (AQI) soaring to 420, reaching the 'hazardous' stage, according to IQAir. The situation mirrored in Kolkata and Mumbai, ranking fourth and eighth, respectively, among the world's top 10 most polluted cities.
In Kolkata, the West Bengal Pollution Control Board reported AQI breaches above 250, while Mumbai's AQI, measured at 234, fell into the 'poor' category, as per the System of Air Quality and Weather Forecasting And Research (SAFAR-India). The Supreme Court's November 7 ban on firecrackers, applicable nationwide, aimed to curb air pollution, particularly in the Delhi-NCR region. However, despite the ban, the night saw an increase in firecracker intensity, raising concerns about the enforcement of restrictions and the overall commitment to combatting air pollution.
