Hyderabad's Silent Smog: Traffic Chokes City Air

Hyderabad is grappling with a worsening air quality situation, predominantly fueled by vehicular pollution. While the city's Air Quality Index (AQI) may appear moderate, particulate matter levels such as PM2.5 are alarmingly high, up to 35 times above World Health Organization (WHO) guidelines. This persistent issue stems from the city's rapidly increasing vehicle population and ongoing traffic congestion.

Recent studies reveal a concerning trend, with PM2.5 concentrations rising significantly between 2011 and 2022, and further accelerating in recent winters. Beyond particulate matter, vehicular emissions are a major source of nitrogen dioxide (NO₂), with Hyderabad experiencing high levels on many days in 2023. Ozone pollution has also spread into residential areas, exceeding safe limits.
