Delhi Awakens to Toxic Haze as Diwali Celebrations Cause Pollution Spike
The Indian capital was shrouded in a thick haze on Tuesday morning, a day after millions of people celebrated the Hindu festival of Diwali with fireworks. The air quality index (AQI) soared to "severe" levels, with some areas recording an AQI of over 500 โ 10 times higher than the level deemed healthy by the World Health Organization.
The pollution was caused by the widespread burning of firecrackers during Diwali celebrations, which has become an annual blight on India's capital. Despite a ban on sale and bursting of firecrackers in Delhi since 2020, the newly elected regional government led by the Bharatiya Janata Party (BJP) had approached the supreme court to relax the ban, citing "green crackers" that are only 30% less polluting.
However, environmentalists and health campaigners expressed frustration over the judges' decision, which allowed green firecrackers to be set off during stipulated time windows. The result was a widespread flouting of the rules across the capital, with little regulation on whether the firecrackers were the more environmentally friendly variety.
The air quality in Delhi peaked at midnight, with pollution levels reaching 15-20 times higher than those deemed healthy. In some areas, PM2.5 and PM10 levels recorded peaks of 1,800 โ a staggering 15 to 20 times higher than safe limits.
This is not the first time Delhi has awoken to toxic haze during Diwali celebrations. The problem has been a recurring issue for more than 15 years, with pollution levels often exceeding those in Beijing, China's former title as the world's most polluted city.
The economic and health toll on Delhi's population of roughly 33 million people is enormous. Exposure to poor air quality increases the risk of neurological, cardiovascular, and respiratory diseases, and can even lead to cancer. The pollution is estimated to be responsible for 10,000 premature deaths a year in Delhi.
As neighboring Pakistan partly blamed India's declining air quality in Lahore on pollutants from the capital, the city's residents were forced to breathe in toxic air. The situation highlights the urgent need for effective measures to reduce pollution during Diwali celebrations and address the root causes of the problem.
