The Public Protection Division continuously monitors air quality at the two sites in Islington shown as green dots on the map at the top right of this page.  The Upper Street site represents the Urban Background, and the results are indicative of the air quality experienced by the majority of Islington residents for most of the time.  The results at the Roadside site on Holloway Road are indicative of the worst conditions in Islington.
The air pollution levels in October were low, with no exceedences of the National Air Quality Standard threshold.
