Air quality

We have a duty to regularly monitor air pollutant levels to assess current and future air quality.

The pollutants of concern are:

  • Nitrogen dioxide
  • Fine particles
  • Carbon monoxide
  • Sulphur dioxide
  • Benzene
  • 1,3 Butadiene
  • Lead
  • Polyaromatic hydrocarbons
  • Ozone

Read more about these air pollutants and their effects.

The United Kingdom Air Quality Strategy 2007 requires we improve areas of poor air quality and reduce any remaining significant risks to health. This will help achieve the wider objectives of sustainable development about air quality in the UK.

Air Quality Management Areas

Areas within West Oxfordshire which don't meet National Air Quality Standards have been declared Air Quality Management Areas (AQMAs). We have produced Air Quality Action plans for these areas to find out the source of the problem and reduce concentrations of air pollutants to below National Air Quality Standards.   

Areas in West Oxfordshire not meeting the objective for Nitrogen Dioxide are:

  • Bridge Street, Witney (Air Quality action plan pending review)
  • Horsefair and High Street, Chipping Norton
