Air pollution

Stockton-on-Tees Borough Council continues to promote good air quality. We monitor the current levels of air quality against National Objectives at a number of locations across the Borough.

Our 3 automatic monitoring stations are at:

  • Eaglescliffe School, monitoring for NO2, PM2.5 and PM10
  • Nelson Terrace, monitoring for NO2 and PM2.5
  • Cowpen Depot, monitoring for NO2

During the 2022 monitoring period, we did not report any pollutants over the annual mean objective at any monitoring location across the Borough.

The most recent data shows a general trend of reductions for NO2 at all automatic sites compared to 2021.

The levels of PM2.5 have increased slightly from 8.3µg/m3 in 2021 to 8.6µg/m3 at Eaglescliffe, whilst at Stockton A1305 the levels have also increased slightly from 7.9µg/m3 in 2021 to 8.7µg/m3 in 2022.

PM10 at Eaglescliffe also increased slightly from 13.5µg/m3 in 2021 to 14.4µg/m3 in 2022. The annual objective for this pollutant is 40µg/m3 therefore the annual objective is not exceeded.

The increase in particulate matter has been attributed to 'high pollution episodes' in March 2022 due to high levels of particulate matter arriving from Europe.

This data and analysis has been fully ratified and confirmed by Defra.
