Impact of gold smelter emissions on vegetation and soils of a sub-Arctic forest-tundra transition ecosystem
Abstract
Surveys were conducted to determine the nature and extent of terrestrial contamination and effects on plant ecology resulting from air pollution in the Yellowknife area of Canada. The survey consisted of widespread sampling of vegetation and soils and a study of plant ecology in a forest stand and on a nearby rocky outcrop at numerous sites. Results indicate that the arsenic level in the soil and vegetation was attributed to gold smelters in an inverse square of the distance from the smelters in a monotonic pattern. In addition, it seems probable that the SO/sub 2/ has been primarily responsible for the depletion of lichens, since analysis of some living specimens indicated very high tolerance for arsenic.
