Air Quality Monitoring in County Wexford

Wexford County Council installed an air monitoring station at Talbot Green, Wexford Town in July 2015 and in Ard Mhicil, New Ross in June 2016. Similiar air monitoring equipment is due to be installed in Enniscorthy and Gorey during 2016/2017.

This equipment measures the amount of small particles in the air such as smoke and emissions from fires and diesel engines. It does this by pumping air through an optical cell, and by shining a laser light through the cell, it is possible to estimate the size of the particles from the light scattered via a number of optical detectors in four different size bands as follows,

  • Total particulates (Blue Line)
  • Particulates 10 micrometers in size, PM10 (Red Line)
  • Particulates 2.5 micrometers in size, PM2.5 (Yellow Line)
  • Particulates 1.0 micrometres in size, PM 1 (Green Line)

It then calculates how much of these particulates are in each metre3 air.

The graphs below are refreshed every 15 minutes and reflect the 24 hour and 7 day data air quality in Wexford Town and New Ross.

Adults and children with lung problems, and adults with heart problems, and older people should avoid strenuous physical activity.    People with asthma may find they need to use their reliever inhaler more often

Reduce physical exertion, particularly outdoors, especially if you experience symptoms such as cough or sore throat

The Air Quality Index for Health (AQIH) can be used by health professionals to help patients who are sensitive to air pollution, manage their condition and reduce their symptoms. The AQIH is based on World Health Organisation Guidelines. Health advice is provided for two groups: those at risk from air pollution and the general population. As a health professional, you may be asked by your patients about whether they belong to an at risk group. Adults and children with heart or lung conditions including asthma are those considered to be at higher risk from air pollution. 

People in at risk groups may experience symptoms when air quality is fair, poor or very poor however those who are highly sensitive to air pollution may even experience symptoms when air quality is good. The general population may experience symptoms when air quality is poor or very poor.
