That bit of London where all the tourists go to mill around at a bus and taxi junction is one of the most polluted parts of any city in the world, with nitrogen dioxide levels peaking at around ten times the EU's recommended maximum.
According to numbers published by the Sunday Times, nitrogen dioxide levels averaged 135 micrograms per cubic metre over the last year, way above the EU's safety limit of 40mcg/m3. One recorded spike saw levels hit 463mcg/m3, rather bad news for the workers, drivers and pedestrians who are in and around the human traffic bottleneck on a daily basis. [Standard]
