Where is Air Pollution being measured within the County Borough?

The Housing and Public Protection Department 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)
• Carbon Monoxide (CO)

The station also monitors 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.

This site is run in conjunction with the Welsh Assembly Government.

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 - eight 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 Housing and Public Protection Department currently uses two portable Partisol's to monitor for PM¹⁰ within the County Borough. These are in addition to the permanent one located at the Victoria Road AURN station.

The two Portable Partisols are currently located in:

• Chirk
• Llay (the monitoring campaign was concluded at the end of March 2005)

Dust Frisbee's

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.
