Air quality deteriorates across India after festive celebrations
· India · Times of India, The Hindu
As Diwali approached, Delhi's air quality plummeted to 'severe+' levels, with PM2.5 concentrations exceeding 300 micrograms per cubic metre in multiple monitoring areas. Firecrackers released a mixture of gases, suspended particles and chemical compounds including PM2.5 and PM10, sulphur dioxide, nitrogen oxides and metallic compounds such as barium and aluminium. Synthetic colours introduced chemicals into water bodies, while large gatherings generated significant plastic waste and loud music contributed to noise pollution. The additional burden compounded existing pollution sources from vehicle emissions, industrial output, construction dust and untreated sewage in India's capital. Authorities have urged stricter enforcement of green crackers and better waste management to mitigate the post-festivity environmental impact.
Why it matters
Residents across Delhi and other northern Indian cities face immediate health risks from toxic air, with vulnerable groups including children, the elderly and those with respiratory conditions most exposed to long-term lung and cardiovascular damage.
