The map shows the (predicted) current state of pollution from the proposed (only) at Charlton Lane.

The red line shows wind direction. Green rings show distance (km). Colours show concentration of oxides of nitrogen at ground level. Maximum: 74.6 ng/m3. This is the concentration at the location that is most polluted by the plume.

Breakdown of pollutants at most polluted location (green = background, red = added by plume):

Oxides of nitrogen
Sulphur dioxide
Particulates
Carbon monoxide
Hydrogen chloride
Hydrogen flouride
