Chippenham Air Quality Map

Chippenham Air Quality monitors now live in four locations

We are now monitoring four locations in Chippenham for Air Quality – Langley Road, Marshfield Road, Wood Lane, and Rowden Hill. The locations are geographically spread around Chippenham and close to main roads. You can click on the buttons below to visit the live environmental dashboard for each location. We are monitoring temperature, relative humidity, air pressure, and Particulate emissions including PM1, PM10 and PM2.5. With this citizen science project we hope to raise awareness of Air Quality in Chippenham.

Thank you to Chippenham Area Board for funding to support this project.

What Particulate Levels are acceptable?

What are Particulates?

PM 10 Particulates are small particles less than 10 micometres in diameter (10 to the power -6 of a metre). PM 2.5 Particulates are less 2.5 micrometers in diameter.

They consist of non gaseous particles in the atmosphere that can enter the blood stream lodging in the heart brain and other organs. Particulates are of considerable concern to human health.

What are the limits?

The Air Quality Standards Regulations 2010 require that concentrations of PM in the UK must not exceed:

  • An annual average of 40 µg/m3 for PM10;
  • A 24-hour average of 50 µg/m3 more than 35 times in a single year for PM10;
  • An annual average of 20 µg/m3 for PM2.5.

World Health Organisation

The WHO has set tighter limits for particulates. The current guidelines state that annual average concentrations of PM2.5 should not exceed 5 µg/m3, while 24-hour average exposures should not exceed 15 µg/m3 more than 3 – 4 days per year.

PM10 (particulate matter with a diameter of 10 microns or less) concentrations of 15 µg/m3annual mean, 45 µg/m3 24-hour mean.
