AIR QUALITY ASSESSMENT

Street Canyons

4.14 A street canyon may be defined as a relatively narrow street with buildings on both sides,
where the height of the buildings is generally greater than the width of the road. Street canyons
may result in elevated pollutant concentrations from road traffic emissions due to a reduced

likelihood of the pollutants becoming dispersed in the atmosphere. Street canyons have been
modelled as part of this assessment along sections of the A2 High Street in both Newington
and Rainham.

Background Concentrations

10
4.15 Background NOx, NO2 and PM10 concentrations have been obtained from Defra . These 1
km x 1 km grid resolution maps are derived from a base year of 2017 (for NOx, NO2, PM10
and PM2.5 only), which the projected to a future year (2019). Background concentrations of
NOx, NO2, PM10 and PM2.5 derived from Defra are provided in Table 4.
