Some really simple measures - as simple as moving to the other side of the street - can help reduce your exposure to traffic pollution in cities:
Research, led by Professor of Environmental Modelling Alison Tomlin from Leeds University's Faculty of Engineering, has shown that air pollution levels change dramatically within small geographical areas dependent on wind patterns, the location of traffic queues and the position and shapes of the surrounding buildings.
The findings showed that pollution hotspots tend to accumulate on the leeward side of the street, (the sheltered side) in relation to the wind's direction at roof-top level.
They also revealed that that carbon monoxide levels were up to four times lower in parallel side streets compared to the main road.
