UK Classification Index µm10 µm2.5 The health effects should be based on 24 hours average values only.
 Good  1 < 16 µg/m3 < 11 µg/m3 Enjoy your usual outdoor activities
2 < 33 µg/m3 < 23 µg/m3
3 < 50 µg/m3 < 35 µg/m3
 Fair  4 < 58 µg/m3 < 41 µg/m3 Enjoy your usual outdoor activities
Adults and children with lung or heart problems, who experience symptoms, should consider reducing strenuous physical activity, particularly outdoors
5 < 66 µg/m3 < 47 µg/m3
6 < 75 µg/m3 < 53 µg/m3
 Poor  7 < 83 µg/m3 < 58 µg/m3 Anyone experiencing discomfort such as sore eyes, cough or sore throat should consider reducing physical activity, particularly outdoors.

Adults and children with lung problems, and adults with heart problems, should reduce strenuous physical activity, particularly outdoors, and particularly if they experience symptoms.
People with asthma may find they need to use their reliever inhaler more often.
Older people should also reduce physical exertion.
8 < 91 µg/m3 < 64 µg/m3
9 < 100 µg/m3 < 70 µg/m3
 Very poor  10 > 100 µg/m3 > 70 µg/m3 Reduce physical exertion, particularly outdoors, especially if you experience symptoms such as cough or sore throat.
Adults and children with lung problems, adults with heart problems, and older people
should avoid strenuous physical activity.
People with asthma may find they need to use their reliever inhaler more often.
