Fine particle pollution in Harrow — and the share of deaths it may explain.

Plain-English context

Fine particles (PM2.5) come from traffic, wood burning, industry and more. Harrow air averaged 8.3 µg/m³ in 2024. Models attribute about 6.2% of deaths among people aged 30 and over to particle pollution. These are modelled estimates, not counted deaths, and Fingertips does not rank areas on them. There is no safe threshold: lower is better all the way down.
