London has breached its annual air pollution limits just five days into 2017, a “shameful reminder of the severity of London’s air pollution”, according to campaigners.
By law, hourly levels of toxic nitrogen dioxide must not be more than 200 micrograms per cubic metre (µg/m3) more than 18 times in a whole year, but late on Thursday this limit was broken on Brixton Road in Lambeth.
Many other sites across the capital will go on to break the annual limit and Putney High Street exceeded the hourly limit over 1,200 times in 2016. Oxford Street, Kings Road in Chelsea and the Strand are other known pollution hotspots.
NO2 pollution, which is produced largely by diesel vehicles, causes 9,500 early deaths every year in London. Most air quality zones across the country break legal limits and the crisis was called a “public health emergency” by MPs in April. This week scientists said that one in 10 cases of Alzheimer’s in people living near busy roads could be linked to air pollution.
