Jul 16, 2024 · Effects on Human Health. Ozone layer depletion increases the amount of UVB that reaches the Earth’s surface. Laboratory and epidemiological studies demonstrate that UVB causes non-melanoma skin cancer and plays a major role in malignant melanoma development.
- Chlorofluorocarbons (CFCs) Chlorofluorocarbons (CFCs) is the name given to a broad class of chemical compounds used as refrigerants containing just three elements: chlorine, fluorine, and carbon.
- Nitrous oxides. In 1970, atmospheric chemist Paul Crutzen studied nitrous oxide (N2O) in the stratosphere. There, the sun’s radiation splits it into nitric oxide (NO) and nitrogen dioxide (NO2).
- Halons (bromocarbons) Halons are molecules containing bromine and carbon. Bromine is a member of the chemical family known as halogens, along with fluorine and chlorine.
Jun 27, 2024 · Ozone depletion, gradual thinning of Earth’s ozone layer caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.

The ozone layer acts as a natural filter, absorbing most of the sun's burning ultraviolet (UV) rays. Stratospheric ozone depletion leads to an increase in UV-B that reach the earth's surface, where it can disrupt biological processes and damage a number of materials.
Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions.
Jan 9, 2024 · Specifically, ozone absorbs harmful ultraviolet B (UV-B) radiation from the sun, which can cause cancer and cataracts in humans, and upsets biogeochemical cycles. Ozone’s beneficial effects are especially impressive given how little ozone actually sits between the sun and Earth’s surface.
