Trees in cities throughout the UK could be significantly improving the quality of the air we breathe by decreasing pollution levels for pedestrians, researchers from the University of Leicester have revealed.

The team from the University of Leicester's Department of Physics and Astronomy found that trees have a regionally beneficial impact by increasing turbulence and reducing ambient concentrations of road traffic emissions - by seven per cent in Leicester City at pedestrian height on average.
