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: 15.5 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):

Oxides of nitrogen
Particulates PM10
Particulates PM2.5
Carbon monoxide
TOC
Cadmium and thallium
Mercury
