Air Quality Bandings for Five Pollutants
| Description of Air Pollution | Low | Moderate | High | Very High |
|---|---|---|---|---|
| Sulphur Dioxide (parts per billion, 15 minute averages) |
less than 100 | 100 - 199 | 200 -399 | 400 or more |
| Ozone (parts per billion) | less than 50ppb 8 hour running average) |
50 - 89 (hourly average) |
90 -179 (hourly average) |
180 or more hourly average) |
| Carbon Monoxide (parts per million, 8 hour running average) |
less than 10 | 10 -14 | 15 - 19 | 20 or more |
| Nitrogen Dioxide (parts per billion, hourly average) | less than 150 | 150 - 299 | 300 -399 | 400 or more |
| Fine Particles (micrograms per cubic metre, 24 hour running average) | less than 50 | 50 - 74 | 75 - 99 | 100 or more |
So any concentration below the threshold level (less than 100ppb as a 15 min average for SO2, for instance) is described as a Low level of air pollution. A level between the threshold level and information level would be described as Moderate, between the information and alert thresholds as High, and above the alert threshold as Very High.
