When chlorine and bromine atoms from CFCs rise and come into contact with ozone in the stratosphere, they destroy ozone molecules, the Environmental Protection Agency says in an online report.

The hole in the ozone layer was discovered 40 years ago, in May 1985. Scientists determined the production of chlorofluorocarbons (CFCs), which were widely used in refrigeration, aerosols ...

BACKGROUND: Previous research suggests that exposures to air pollution and nonoptimal temperatures are associated with a ...

A reaction mechanism is a sequence of elementary reactions that can explain how an overall chemical reaction proceeds. Gold redox catalysis has remained challenging owing to the high redox ...

Our use of ozone-depleting substances such as chlorofluorocarbons (CFCs) had torn a hole in the ozone layer that protects us from the sun’s harmful ultraviolet radiation. United Nations ...

In 1989, the Montreal Protocol outlawed the use of CFCs but the ozone layer is still yet to ... which play an important part in the chemical reactions. As the sun rises over the pole, the sun ...

These particles: Factor Impact on Ozone Layer Composition 40% of a typical Starlink satellite consists of aluminium. Chemical Reactions Aluminium oxide particles can act as catalysts in ozone ...

The increased frequency during the high pollen season lends weight to the widely accepted hypothesis that VKC is an immunologically mediated hypersensitivity reaction to environmental antigens.
