The map shows the (predicted) current state of pollution from the proposed incinerator at Barton Stacey / Longparish, Hampshire (with 80m stack).

The red line shows wind direction. Green rings show distance (km). Colours show concentration of oxides of nitrogen at ground level. Maximum: 44.6 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
Sulphur dioxide
Carbon monoxide
Particulates
Hydrogen chloride
TOC
Hydrogen flouride
Ammonia
Cadmium and thallium
Mercury
Other metals
PAHs
Dioxins and furans
