Air quality and forestry
The source and nature of air pollutants are reviewed in relation to tree growth with emphasis on SO/sub 2/ and fluorides. Damage from SO/sub 2/ can result to conifer foliage from continued fumigation at concentrations exceeding 0.2 ppm. Hydrogen fluoride is toxic to some plants in concentrations as low as 0.1 ppb. The kind of damage depends mainly on the nature of the pollutant, the concentration, the atmospheric conditions, and the duration of fumigations. The contribution of trees in combating air polution involves the recognition and application of genetic variation between tree species in resistance to certain pollutants, as well as genetic variations of clonal lines of trees within a species. More information is needed on the entire air quality problem in order that research and control measures can meet the need of future generations.
