Air quality and monitoring
All local authorities have a legal duty to out to carry out annual reviews of air quality in their area. Pollutant levels are reviewed and assessed against government air pollution objectives set out in the national air quality strategy. These pollutants are:
- Carbon Monoxide
- Nitrogen Dioxide
- Sulphur Dioxide
- Particulates (PM10)
- 1, 3 - Butadiene
Areas identified with pollutant levels that may be at risk of going above the objectives are declared as Air Quality Management Areas (AQMA).
Annual reports are published showing changes in air pollution concentrations and progress towards achieving the national air quality objectives.
