Document Summary
One clo molecule can catalyze the destruction of many thousands: chlorine is converted to water-soluble chemicals such as hydrogen chloride, hcl, which can be deposited from the. The ice particles in pscs provide a larger surface area for cfcs and other ozone depleting molecules to react with the ozone and destroy it much more effectively. Ozone losses are also found in middle-latitude regions (united. Carbonyl sulfide from the ocean and human pollution are the most significant sources of sulfide into the atmosphere. 46% increase in non-melanoma skin cancer over seven years, correlated with an increase in uvb radiation. Radiation is much higher at the equator than at the poles (1000 times), and higher elevations also experience more radiation. Cyanobacteria, which produce much of the world"s oxygen are sensitive to increases in uv radiation, as well as for the retention of nitrogen in the roots of plants.
