The above index is for overall Air Quality in Zone C and not just at this station. The index is calculated based on the latest available measurements of ozone, nitrogen dioxide, PM10 and sulphur dioxide in Zone C.
The Limerick site was located in the yard of the Fire Station on Mulgrave Street. 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 26/01/2000 to 13/11/2000 and compared with the Assessment Thresholds in the Air Quality Regulations to determine the type of monitoring required long term.
