Where is Air Pollution being measured within the County Borough?

The Public Protection Service monitors air pollution in numerous locations throughout the County Borough using many different techniques:

Automatic

The Automatic Urban and Rural Network (AURN) station is located on Victoria Road and continuously monitors for:

  • Oxides of Nitrogen (NOx)
  • Sulphur Dioxide (SO2)

The stations also monitor for Particulate Matter (PM10) though due to the technology of the monitor, this is not real time and the results need to be determined in a laboratory.

Both sites are run in conjunction with the Welsh Assembly Government. The Victoria Road station is also a member of the Automatic Urban and Rural Network (AURN) which is a national network of Air Quality monitoring stations.

Diffusion Tubes

This is the most widely used Air Quality Monitoring technique used by the Housing and Public Protection Department. There are currently over twenty diffusion tubes exposed each month within the County Borough:

Nitrogen Dioxide

  • Chirk - two tubes
  • Plas Madoc - one tube
  • Rhostyllen - two tubes
  • Ruabon - one tube
  • Wrexham Industrial Estate - one tube
  • Wrexham Town - nine tubes

Sulphur Dioxide

  • Brymbo - one tube
  • Chirk - one tube
  • Llay - one tube

Ozone

  • Chirk - one tube

Benzene

  • Rhosllanerchrugog - one tube
  • Wrexham Town - one tube

Partisol Plus PM10 Monitors

The Public Protection Service currently uses two Partisol’s to monitor for PM10 within the County Borough.

The two Partisols are currently located in:

  • Wrexham Town - Victoria Road
  • Isycoed

Dust Frisbees

The Dust Frisbee’s are designed to be used in relation to nuisance dust monitoring, and as such are placed where required, which is often in local residents gardens where they are left for increments of one month until the monitoring period is completed.
