New Delhi's Air Quality Deteriorates Post-Diwali Fireworks
• Air pollution in New Delhi surged dramatically following Diwali celebrations on 9 November
• Toxic levels of PM 2.5 microparticles reached 879 micrograms per cubic metre in the Mandir Marg area, which is nearly 59 times the World Health Organisation's recommended daily limit. Despite the Supreme Court's allowance for limited use of 'green' firecrackers, widespread violations were reported, exacerbating the city's already severe winter smog. The pollution is attributed to multiple sources, including vehicle emissions, farm stubble burning, industrial activities, and secondary particles formed in the atmosphere. Authorities have implemented restrictions on traffic and construction in recent weeks to mitigate the smog, but the situation remains critical.
Impact & Risks
The toxic air quality poses severe health risks to New Delhi's population of over 30 million, including respiratory and cardiovascular issues. Vulnerable groups such as children, the elderly, and individuals with pre-existing health conditions are at heightened risk. A study published in 2024 linked 3.8 million deaths in India between 2009 and 2019 to air pollution, underscoring the long-term health implications. The current pollution levels may lead to increased hospitalisations and reduced outdoor activity, further straining healthcare systems.
