The Liverpool Friends of the Earth Air Quality project finished May 2017. The final presentations are available in the links below.
It is very important to stress that this data must be treated with caution. To put it simply: it is not possible to say that a single air quality reading on a particular day means that air quality is poor for that area. This issue is much more complex than that.
Thanks again to the members of Breathe Easy, other volunteers and the Liverpool CCG who helped during the project.
