Monitoring local air quality

Why do we monitor pollutants in Islington?

We have collected air quality information since the 1960s. This information helps us assess air quality in the borough and see whether we are meeting air quality standards.

We can use this information to assess how effective policies and activities are, provide central government with information that can help inform policies and let the Islington community know about air pollution affecting them.

The main air pollutants that we focus on in Islington are particulate matter (PM10 and PM2.5) and nitrogen dioxide (NO2).

The main source of these pollutants is transport, in particular diesel vehicles. Boilers, from residential and commercial properties, also contribute.

Where do we monitor pollution?

We have a network of air quality monitors (diffusion tubes and automatic monitors) across the borough. These are located to measure:

  • background pollution in less polluted areas to measure levels of pollution residents are exposed to most of the time.
  • the most polluted areas in the borough such as busy road junctions. These sites indicate the highest level of pollution people will be exposed to in the borough.

What are the pollution levels in Islington?

Our air quality monitors are part of the London Air Quality Network through King's College Environmental Research Group, which provides current and historical air quality information. 

AirTEXT can provide you with further information about current and forecast pollution levels and if you sign up for alerts you will be warned about upcoming high pollution by phone, text or email.
