The news

What we know

Researchers comparing 2024–2025 monitoring data report higher PM2.5 in Chennai across seasons, with traffic, construction dust, and episodic fires cited as drivers. The story still positions Chennai below peak polluted northern cities on annualised averages.

Policy discussion ties to BS-VI enforcement, construction mesh rules, and waste-burning complaints.
