Abstract |
The two chapters summarize the effects expected from the depletion of stratospheric ozone by the presence of CFCs. The two areas considered by these two reports are materials damage and atmospheric processes. Increased UV can affect materials in the following ways: (1) corrosion of metals is expected to increase because of increased acid deposition; (2) stone deterioration is expected to increase again because of increased acid deposition; (3) dyes are expected to fade more quickly; (4) polymers are expected to breakdown more rapidly; and (5) paints will weather faster. In the area of atmospheric processes, increased UV is expected to: (1) increase photochemical reactions in cities and more ozone is expected; (2) sulfur dioxide is expected to oxidize to sulfate more quickly; and (3) gas-particle reaction rates are expected to increase. |
