A study along a line NNE. from the metal smelter at Falconbridge, Ontario, reveals that strong sulphate accumulation in the surface soil occurs only within about one mile of the chimneys emitting sulpur dioxide pollution while effects upon the soil drainage waters are marked to a distance of nearly two miles, and still clearly evident 10 or more miles away. The number of species present in the flora declines sharply within about four miles of the smelter, but certain species (e.g. Pinus strobus, Vaccinium myrtilloides) disappear at much greater distances. Among the most tolerant species are Acer rubrum, Quercus rubra, Sambucus pubens, and Polytonum cilinode.
