HEALTH IMPACT

Particulate air pollution

3.8% of mortality attributable to particulate air pollution
2024 Not compared

This OHID measure estimates the mortality burden associated with particulate air pollution. It is a health-impact measure, not a pollution concentration.

Annual PM2.5 is Defra Pollution Climate Mapping data. Monitoring readings are station-specific UK-AIR measurements and may be provisional.
