Air Quality Management

Stratford-on-Avon District Council aims to provide an attractive, clean and safe environment for both residents and visitors. In order to do so, the council is committed to protecting and, where necessary, improving local air quality.

Nationally, most air pollution is caused by emissions from motor traffic, and urban air quality is once more causing public concern. To increase public awareness, the Government issues daily air quality bulletins via the national media. These bulletins include health advice for those who may be especially affected by high concentrations of air pollutants.

The air pollutants that may cause health effects are ozone, particulate matter (PM10), carbon monoxide (CO), sulphur dioxide (SO2), nitrogen dioxide (NO2) and volatile organic compounds (VOCs). The first five are used by the Environment Agency to classify air quality with reference to the risks to human health. The classifications are:

  • Low: Effects are unlikely to be noticed even by individuals sensitive to air pollutants.
  • Moderate: Mild effects, unlikely to require action. May be noticed among sensitive individuals.
  • High: Sensitive individuals may notice significant effects and action to avoid or reduce these effects may be needed (e.g. reducing exposure by spending less time in polluted areas). Asthmatics will find their 'reliever' inhaler is likely to reverse the effects on the lung.
  • Very high: The effects on sensitive individuals described for 'High' levels of pollution may worsen.

Although less serious than the smogs of the 1950s, pollution concentrations regularly exceed international health guidelines in some UK towns and cities and reach the classification of very high.
