Air Pollution in the Underground

Did you know that every time you go underground in a tube station you have been breathing in air pollution? You have been breathing in up to 30 times as much particulate pollution than on the streets of London. When trains wheels scrape on the platform it creates more pollution. This is partly due to being the oldest underground transport in the world. The particles are different from the ones outside and they don't know the effect on our health, they will keep an eye on this.
