The Environmental Protection Agency manages the National Ambient Air Quality Network.
The Air Quality Index for Health is calculated every hour and tells you if air quality is good, fair, poor or very poor in your region. The above index is for overall air quality in the Large Towns AQIH Region. You can find out if air quality is likely to affect your health and what you can do to protect your health on the Air Quality Index for Health page.
The current Ennis site is located on the grounds of Ennis town council, close to the centre of the town. Monitoring is done using continuous monitors for sulphur dioxide and particulates (PM2.5 and PM10).
An air quality assessment for all required parameters was carried out at Ennis in 2006/2007. The site was located in the Ennis Town Council yard. During the assessment monitoring was done by a mobile unit containing continuous monitors for sulphur dioxide, nitrogen oxides, carbon monoxide and benzene. Continuous samples were also taken for particulates PM10 and lead.
Results were collected from 25th January 2006 to 18th April 2007 and compared with the Assessment Thresholds in the Air Quality Regulations to determine the long term monitoring necessary.
