This report describes symptoms of these pollutants and of natural stresses that may appear similar. The industries discussed include natural gas processing plants, oil wells and refineries, oil sand plants, metal mines and smelters, cement plants, potash industry, pulp and paper mills, and agricultural chemical production and application. Nineteen pages of color photographs provide examples of these symptoms on forest vegetation.

Atmospheric dispersal of these pollutants has resulted in over 50 square miles of patchy forest decline. All components of the forest vegetation exhibit effects of direct pollutant disposition. Impacts range from patches of tree decline and mortality through to general depletion of sensitive cryptogams. This decline will intensify and the area of decline will expand under current pollutant emission rates. Contamination of soil organic matter has been detected over a much greater area. Levels of sulphur and nickel are highly elevated near the smokestack and decrease with distance from it. Nickel and possibly other heavy metals are building up to toxic levels which will be impossible to correct economically. This represents a high potential for severe site degradiation as a further outcome to aerial dispersal and dilution of the smelter wastes.
