Tehran Faces “Very Unhealthy” Air Quality as Pollution Levels Spike
TEHRAN, Iran – November 22, 2025 – residents of Tehran are experiencing “very unhealthy” air quality today, with the city ranking as the fourth most polluted major city globally as of 5:50 AM Pacific Time. Data from IQAir indicates an AQI exceeding 200,primarily driven by high concentrations of PM2.5 particulate matter.
The poor air quality poses significant health risks, perhaps causing respiratory problems, exacerbating heart disease, and impairing lung function, especially for children, the elderly, and individuals with pre-existing health conditions. authorities advise limiting outdoor activity, closing windows, wearing masks when venturing outside, and utilizing indoor air purifiers.
Air quality in Tehran is known to fluctuate, but conditions are expected to improve later tonight, potentially falling below an AQI of 120. However, experts emphasize that lasting improvements require addressing the root causes of pollution, not simply relying on temporary meteorological changes.
Several factors contribute to tehran’s air pollution crisis: emissions from the energy sector – specifically the increased use of heavy oil and coal in power plants – traffic and transport, particularly older diesel vehicles, industrial sources, and seasonal dust movement from surrounding deserts. Recent analysis suggests that fuel choices and energy policies have significantly worsened pollution levels and thier associated health impacts.
