Abstract
Indices of atmospheric purity (IAP) of 42 sites located in all directions from the aluminum factory at Arvida and spread out in about 250-km2 area, were determined on the basis of phytosociology of epiphytes of Populus balsamifera. These index values ranging from 0 to 103 were arranged into six groups and the investigated area was accordingly delineated into six IAP zones to represent areas with different levels of fluoride pollution. A relative picture of the approximate limits of fluoride contamination in different zones is obtained by the fluoride accumulation in Parmelia sulcata thalli transplanted at various sites in the area.
