Materials
Materials at greatest risk from exposure to acidic
deposition include metals, such as steel and zinc,
and stone masonry. Regions at greatest risk cor
respond to those with the greatest population den
sities and areas with historically significant buildings
and monuments, Scientists estimate that the bulk
of materials damage is caused by local scale pol
lutants, and that sulfur dioxide emissions are re
sponsible for a major share of pollutant induceddamages to a broad range of materials, Elevated
ozone concentrations are harmful to such materials
as paint on home exteriors and rubber. The dis
tribution of materials sensitive to air pollutants is
not well known, since inventories have been taken
in very few areas.
