Air pollution in 2011 was so high in London that EU limits were exceeded at most monitoring sites close to busy roads, according to figures released today by the London Assembly.

Research at 100 monitoring sites by King’s College London found limits for harmful Nitrogen Dioxide (NO2) were breached at the majority of locations close to roads, with the worst pollution levels – over three times the limit – measured in Putney and Brixton.

The King’s College London research also found limits for PM10 – which is linked to respiratory and cardiovascular conditions – were exceeded at two kerbside monitoring sites, three roadside sites and one industrial monitoring site.
