The map shows the (predicted) current state of pollution from the proposed incinerator at Balaclava Bay.

The red line shows wind direction. Green rings show distance (km). Colours show concentration of oxides of nitrogen at ground level. Maximum: 10.3 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
Carbon monoxide
Particulates
Hydrogen chloride
VOCs
Hydrogen flouride
Ammonia
Cadmium and Thallium
Mercury
Other metals
PAHs
Dioxins and furans
