Air Quality and Public Health

We monitor air quality to protect and inform the community



We currently use diffusion tubes to monitor NO2 at 29 strategically placed locations across the borough. They are distributed on a monthly basis and returned to a laboratory for analysis.

We currently have an automatic road side air quality monitor in Hatfield that monitors the pollutant PM2.5.

We are part of the Hertfordshire and Bedfordshire Air Pollution Monitoring Network and our monitoring data can be found on the Hertfordshire & Bedfordshire Air Quality website.

The air quality in the Borough of Welwyn and Hatfield is currently good and we are working hard to try and maintain this.

For more information on the work we do please have a look at the following reports:
