Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, at which locations in London air pollution levels in 2014 exceeded the EU limit on (a) NO2, (b) Ozone, (c) PM10 particles and (d) PM2.5 particles.

9 of the 17 Defra Air Quality monitoring sites in London measured an exceedance of EU limits for NO₂ in London during 2014: Camden Kerbside, Haringey Roadside, London Bloomsbury, London Hillingdon, London Marylebone Road, London Westminster, Southwark A2 Old Kent Road and Tower Hamlets Roadside. In addition to the measured exceedances, there were also a number of modelled exceedances of the EU limit for NO₂ in London in 2014.

None of the 17 Defra Air Quality monitoring sites in London exceeded the EU Target Value for Ozone (O₃), but 5 of the 17 measured an exceedance of the EU long term objective during 2014: London Haringey, Priory Park South, London Hillingdon, London North Kensington, London Teddington. In addition to the measured exceedances, there were also modelled exceedances of the EU long term objective for O₃ in London in 2014.
