TII and Air Quality
TII Monitoring of Nitrogen Dioxide adjacent to the M50
In June 2018, TII commenced a measurement campaign of Nitrogen Dioxide (NO2) at locations adjacent the M50. Measurements were made using diffusion tubes. Whilst the diffusion tube method is useful, they are 'indicative' only. This means that they only give us an estimate of longer-term average nitrogen dioxide concentrations.
In 2011, the National Roads Authority (NRA) published the Guidelines for the Treatment of Air Quality During the Planning and Construction of National Road Schemes (Revision 1). The revised guideline document provides a step-by-step approach for the integration of air quality considerations into the various planning phases of the 2010 National Roads Project Management Guidelines (NRPMG).
These Guidelines also provide information on the Air Quality Standards Regulations (S.I. No. 180 of 2011).
