Check air quality

We have six Air Quality Monitoring Stations (AQMS) at these locations:

• Old Kent Road
• Elephant and Castle
• Tower Bridge Road
• Lower Road
• Vicarage Grove
• South Circular Road

These stations measure air pollution every hour, including:

• nitrogen dioxide (NO2)
• particles (PM10 & PM2.5) 

At the Elephant and Castle AQMS, we also monitor ozone (O3).

Nitrogen dioxide diffusion tube survey

We also measure monthly averages of nitrogen dioxide (NO2) at several locations across the borough using NO2 diffusion tubes.

You can download our Nitrogen Dioxide monitoring data for the years 2012 to 2022.

airTEXT predicts harmful pollution levels in London. The service will message you by text, voicemail or email.

The messages will offer health advice based on expected pollution levels. For example:

• take your inhaler or angina spray with you
• take extra doses if symptoms get worse
• avoid strenuous outdoor activity
