Ambient Air Quality Assessment at Mountrath

The Environmental Protection Agency manages the National Ambient Air Quality Network.  Find out more information on what we monitor.

The assessment results from Mountrath were used in the assessment of Zone D monitoring needs.

  • PM10 - above upper assessment threshold
  • NO2 - below lower assessment threshold
  • CO - below lower assessment threshold
  • SO2 - below lower assessment threshold
  • Benzene - below lower assessment threshold
  • Pb - below lower assessment threshold

Mountrath is in Zone D of the country, rural areas. The implications of this assessment are that within Zone D

  • Levels of PM10 will need to be monitored continuously.
  • Levels of CO, SO2, NO2, benzene and lead can be assessed using modelling or objective estimation techniques.

The directive states that modelling or objective estimation techniques may be used to assess ambient air quality if levels of the pollutant in question in that zone are below the lower assessment threshold.  Continuous monitoring is required if levels exceed the upper assessment threshold.
