Hyderabad’s air gets cleaner, but PM10 pollution remains a concern
- Hyderabad’s PM2.5 levels fell by around 2.86% annually between 2017 and 2023, a seven-year study found.
- Despite the decline, the city’s average PM2.5 concentration remained 23% above its historical mean from 2001 to 2022.
- PM10, or coarse particulate pollution, increased during the period, with construction, road dust and traffic contributing to the rise.
- The study by National Atmospheric Research Laboratory scientists found local human activity was a major contributor to PM10, while some severe pollution episodes were linked to pollutants transported from other regions.
