Air quality has a big effect on human health, the natural and man made environment and the climate.

The National Air Quality Strategy - published in 1997 - outlined recommended maximum levels of eight pollutants.

  • Benzene
  • 1,3 Butandiene
  • Carbon Monoxide
  • Sulphur Dioxide
  • Lead
  • Particulates
  • Nitrogen Dioxide
  • Ozone.

The maximum levels have been devised by the Expert Panel on Air Quality Standards (EPAQS) based on medical and scientific evidence.

What is our role?

All councils have to assess the present and future air quality of their area in relation to the requirements of the National Air Quality Strategy - and identify the main sources of the pollutants affecting air quality.

The National Air Quality Strategy sets out three stages of review and assessment for councils to follow.

Stage one

Involves a simple analysis of each pollutant. If significant quantities of one or more of the pollutants are found stage two is put into action.

Stage two

A more detailed analysis is carried out using existing data in order to estimate maximum concentrations of air pollution within the district. An assessment regarding the issue of attainment of the objectives is also carried out. If it is unlikely that the required levels will be met stage three is put into place.

Stage three

Involves a detailed study of specific locations possibly resulting in the area becoming an Air Quality Management Area which involves a 12 month assessment to establish exact sources and the extent to which the national objectives will be overreached.
