Air Quality Monitoring

As part of the process of detailed assessment of the air quality around the A414, monitoring data was needed to check that the air quality model used was providing accurate results.

 

The Council set up and maintains an air quality monitoring station at Potter Street School, continuously monitoring fine particles [often called “PM10”] and Nitrogen Oxides, both emitted by traffic.

 

To cover a wider geographical area, passive diffusion tubes are used to collect average nitrogen dioxide levels at a number of sites.

 

Results from the air quality station and from the diffusion tube sites are shown on the Air Quality Consortium Website, www.essexair.org
