EPA Provides Real Time Air Quality Monitoring in Ennis

Date released: Mar 07 2006

Real time air quality data for Ennis is now available on the Environmental Protection Agency (EPA) website http://www.epa.ie/whatwedo/monitoring/air/.  The EPA began assessing air quality in Ennis on 24th January 2006, using an EPA mobile laboratory positioned at the premises of Ennis Town Council.

The assessment will take place over a period of approximately six months and concentrations of the following substances will be measured. 

  • Oxides of nitrogen
  • Sulphur dioxide
  • Ozone
  • Benzene
  • Lead
  • PM10 and PM2.5– very small dust particles

This work is part of a comprehensive assessment of air quality in all major cities and towns in Ireland. 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). Ennis is in Zone C of the country along with other specified cities and towns with a population greater than 15,000.

The EPA is using mobile air quality laboratories such as the unit located in Ennis to carry out assessments of air quality in all Zone C cities and towns.  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.

The EPA gratefully acknowledges the assistance of Clare County Council and Ennis Town Council.
