Air pollution levels in India’s capital soared off the charts once again as millions of Indians burst fire crackers to celebrate Diwali, the Hindu festival of lights, despite a Supreme Court ban on the sale of fireworks in the region.
Already one of the world’s most notoriously polluted mega cities, the capital saw its air quality index (AQI) gradually worsen until it reached a level of 1,031 on Diwali, according to the US embassy in New Delhi. A reading of 0-50 is considered good, while levels between 300 and 500 are considered “hazardousâ€. Anything above 500 is considered “Beyond Indexâ€. The US embassy showed New Delhi’s pollution had nearly halved with AQI at 548, which still appeared to be the worst of any major city in the world.
