To highlight the issue of pollution in the city of Bath and make Nitrous Oxide data more accessible to residents, the artist Alison Harper has put together 69 red bicycle wheels to represent the illegal limit of Nox that is regularly breathed in by Bath residents. Many parts of Bath regularly exceed the European guideline of 40 micrograms, which is considered safe for human health.

Poor air quality is the number one environmental cause of premature mortality, with over 400,000 premature deaths every year (

Thus the red wheels are a symbol of a potent danger that affects us all and suggests we need a change in our behaviour. How can we become a part of the solution and not the problem?
