If you think London’s streets are polluted, wait until you go underground.

According to a new study commissioned by Transport for London, the air in parts of the city’s subway system is thick with harmful particulates, with some of London’s Tube stations registering levels of air up to 30 times worse than the average for a London street above ground.
