Air Quality Monitoring in Letterkenny

Date released: Jun 20 2008

Letterkenny  now on the EPA website. This work is part of a comprehensive assessment of air quality in all major cities and towns in Ireland.

The EPA began assessing air quality in Letterkenny on 16th May 2008 using an EPA mobile laboratory located in the grounds of the Donegal County Museum on High Road.  The assessment will take place over a period of approximately six months and concentrations of the following substances in air will be measured:

  • Oxides of nitrogen
  • Sulphur Dioxide
  • Carbon Monoxide
  • Lead
  • PM10
  • Benzene and Toluene

The European Union’s recent directive on air quality has established the concept that each country should be divided into zones for the purpose of assessing and managing air quality. Ireland is divided into four zones; Dublin (A), Cork (B), selected population centres >15,000 population (C) and non-urban areas (D).

Letterkenny is in Zone D of the country. The EPA is using mobile air quality laboratories to carry out assessments of air quality around the country.  During each assessment, concentrations in air of the substances listed above are measured and compared to limit values set out in the European Union’s recent framework directive. A report is produced after each assessment.

Initial results from the assessment show that levels of all parameters being measured are well below limit values set for the protection of human health. Real time air quality results from the monitoring in View real time air quality data for Letterkenny  can be viewed throughout the assessment.

The EPA gratefully acknowledges the assistance of Donegal County Council, Letterkenny Town Council and the staff of the Donegal County Museum.
