RATE OF OZONE POLLUTION SLOWS, RESEARCHERS SAY

The increase in concentration of chloroflurocarbons in the atmosphere has been reduced by half since industrial nations agreed to phase out manufacture of the ozone-depleting chemical, researchers said Monday.

Despite that good news, experts said chloroflurocarbons already released into the atmosphere will continue to savage ozone, the natural chemical that protects Earth from the sun's radiation.

At the national meeting of the American Association for the Advancement of Science, researchers reported that the chloroflurocarbons, or CFCs, increased at the rate of 4 percent annually through the 1980s, but the rate has now slowed to about 2 percent.
