Closing the window on air pollution

Written by Emma Turner for Chemistry World

Graphical abstractSwitching off fans and closing car windows can minimise drivers’ exposure to harmful particles.

Sitting in traffic is bad for your lungs, but closing your car windows and switching off the fans can minimise the amount of micro-size pollution particles you breathe, scientists from the UK found.
Air pollution is a major health risk. The World Health Organization estimates that it caused 3.7 million premature deaths in 2012. Last year, a group led by Prashant Kumar from the University of Surrey, UK, showed that drivers stuck at traffic lights are exposed to 29 times more harmful pollution particles than those driving in free flowing traffic.
