The map shows the (predicted) current state of pollution from the proposed incinerator at Trostrey Court Farm.

The red line shows wind direction. Green rings show distance (km). Colours show concentration of oxides of nitrogen at ground level. Maximum: 62.2 µg/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):
