Historical trend

Trend summary

Fine particulate pollution (PM2.5) was 7.2 µg/m³ in 2024, down from 7.5 µg/m³ in 2023.

Trend

  • Over the available record (2009–2024), it has ranged from 7.2 µg/m³ in 2024 to 12 µg/m³ in 2010.
  • The most recent reading is the lowest in the available record.

Context

  • DEFRA Air Quality Statistics (fig06) report annual mean PM2.5 at urban background monitoring sites across England; this is the standard measure for population exposure.
  • The WHO PM2.5 guideline of 5 µg/m³ was tightened in 2021; UK regulations require an annual mean below 10 µg/m³ by 2040 in England.
