Fact of the Day

Nearly 9,500 people die each year in London because of air pollution, twice as many people as previously thought die prematurely from pollution in UK capital. The premature deaths are due to two key pollutants, fine particulates known as PM2.5s and the toxic gas nitrogen dioxide (NO2), according to a study. NO2 gas is largely created by diesel cars, lorries and buses, and affects lung capacity and growth.
