Areas have been ranked by PM2.5 concentrations recorded in 2019 by the Department for Environment and Rural Affairs (Defra).

PM2.5 are solid or liquid particles with a diameter at least 30 times smaller than the width of a human hair. It can be naturally occurring, such as from sea spray or dust storms, or man made, from soot caused by burning fuels for transport, industry and heating.
