Delhi, India, is currently grappling with hazardous air quality levels, according to the World Health Organization (WHO). Data collected by IQAir reveals a concerning rise in PM2.5 levels (atmospheric particulate matter with a diameter of less than 2.5 micrometers) over the past two days, surpassing already unhealthy levels observed in recent weeks. The WHO estimates that ambient air pollution led to approximately 4.2 million premature deaths worldwide in 2019.
The deteriorating air quality has prompted the closure of some schools and the imposition of a ban on non-essential construction activities in the city. Dr. Nikhil Modi from Apollo Hospital in Delhi highlighted the immediate health impacts, noting an increase in patients with respiratory issues, including coughs, colds, and eye irritation. He stressed the importance of wearing masks and minimizing outdoor activities, particularly for vulnerable populations.
Regional officials attribute the worsening conditions to a seasonal combination of lower temperatures, limited wind movement, and agricultural crop stubble burning in neighboring states. This convergence of factors has exacerbated air pollution levels, demanding urgent attention and concerted efforts to mitigate the crisis.
