We knew it before the Evening Standard used the Freedom of Information Act and discovered, “Levels of toxicity are up to three-and-a-half times the EU legal limit – and all of the country’s worst blackspots for dirty air are in the capital.”
But where’s our proof?
Then we went and placed small diffusion tubes around Bethnal Green Road, Hackney Road/Columbia Road, Redchurch Street, Arnold Circus and Club Row. The tubes measure the levels of nitrogen dioxide – the toxic gas that is closely linked to asthma and other respiratory problems, and causes such grief to many local people.
We left the tubes there and then collected them after one week. The London Sustainability Exchange is currently analysing the data. Watch this space for their results.
But don’t breathe too deeply…..
