A recent study conducted by Respirer Living Sciences in November 2024 uncovers the alarming local spikes in PM2.5 pollution across Bengaluru. Though the city’s average PM2.5 level is relatively low compared to other major cities, certain areas are suffering from severe pollution due to high traffic and industrial activities.

The study found that Bengaluru’s PM2.5 levels averaged at 39 µg/m3 in November 2024, staying within the 60 µg/m3 threshold but showing troubling pollution clusters. Some of the highest pollution points were observed in Jigani (51.7 µg/m3), Jayanagar (46.8 µg/m3), and Mailasandra (45.8 µg/m3). These fine particles, mainly released from vehicles and factories, are linked to respiratory and heart diseases, posing a serious health threat to residents.

Experts emphasize the need for a hyperlocal air monitoring system to tackle these pollution surges. While the city has installed several Continuous Ambient Air Quality Monitoring (CAAQM) stations, these are insufficient on their own. A combination of mobile monitoring tools and pollution sensors could provide more accurate data, enabling targeted action.

Further supporting this call for action, a CSTEP study highlighted pollution hot zones along major roads, where traffic emissions peak. This data could help identify sources and allow quicker responses, such as improving public transport and promoting sustainable practices.

Incorporating real-time pollution tracking and immediate action can significantly reduce Bengaluru’s air quality issues and safeguard public health.
