We monitor air quality to protect and inform the community

We currently use diffusion tubes to monitor NO2 at 33 strategically placed locations across the borough. They are distributed on a monthly basis and returned to a laboratory for analysis. We also have a BAM1020 PM2.5 automatic roadside air quality analyser located in Hatfield.

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. Please also look at our air quality progress reports under related media.

We are pleased to advise that DEFRA have now appraised and approved the air quality status report for 2019. The report is available to view as a PDF document under related media. The DEFRA feedback report is also available under related media.

Air pollution alerts

You can sign up to an alert service which sends you a text or email when levels of air pollution in your area increase to a moderate level or above. The alerts are sent out before moderate, high, or very high levels of air pollution are forecast.

It's free to sign up and enables you to find out when air pollution is at elevated levels in the area in which you live, work, or travel. The service is provided by our partners, Ricardo Energy and Environment.
