25 million people use Edinburgh Waverley station annually. Hundreds work there eachday and thousands pass though it daily
Exhaust fumes from trains and taxis, coupled with toxic dust kicked up by construction works, are endangering the health of commuters, tourists and workers – particularly those with asthma, lung or heart conditions, experts say.
Scientists measured levels of nitrogen dioxide, a gas emitted by vehicle exhausts that damages the lungs, blood and immune system, at four locations around the concourse. They found average levels varying from 205 to 304 micrograms per cubic metre, compared with the annual average "air quality standard" of 40 required by European law. The concentrations of nitrogen dioxide in the station were four to six times higher than in the surrounding streets.
Scientists also found high levels of tiny particles known as PM10s, which inflame lung tissue and increase the risk of heart attacks and strokes. They were nearly twice as high as the air quality standard, and up to 10 times higher than in nearby streets.
Highly toxic diesel pollutants known as polycyclic aromatic hydrocarbons, or PAHs, were four times higher than the relevant air quality standard, according to the report. They are blamed for causing cancers.
