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 August were generally low, with the National Air Quality Standard threshold only being exceeded for airborne particulates over a 24 hour period around the 24th.
Temporary faults with the air quality monitoring equipment has resulted in there being no data for the Holloway Road site from the 5th to part way through the 8th of the month, and around the 30th for the Upper Street site.
