Table of UK Air Pollution Banding

For current UK air pollution levels with health effect bandings click here.

Pollution Band (Index) Health Impact
Low (1-3) Effects are unlikely to be noticed, even by people who know they are sensitive to air pollution.
Moderate (4-6) Mild effects are unlikely to require action, but may be noticed by sensitive people.
High (7-9) Sensitive people may notice significant effects, and may have to take action to reduce or avoid them (for example, by reducing time spent outdoors). Asthmatics will find that their ‘reliever’ inhaler is likely to reverse the effects of pollution on their lungs.
Very High (10) The effects on sensitive people, described for ‘high’ levels of pollution, may worsen.
