Fluorocarbon and Ozone

* Fluorocarbon

Fluorinated hydrocarbons are collectively referred to as "fluon" in Japan. Fluorocarbon is a compound invented by Thomas Migley in the United States in 1928, and it has many excellent properties, if we leave aside its negative impact on the global environment.

Thus, the annual consumption of CFCs has increased from about 3,000 tons in the 1930s when industrial production of CFCs started. In the 1930s, when industrial production of CFCs began, the annual consumption of CFCs was about 3,000 tons, but by 1986, it had reached more than 1.1 million tons.

* Ozone

Ozone exists in the stratosphere 10 to 50 kilometers above the ground at a concentration of more than 15 PPM. This is because oxygen molecules (O2) in the atmosphere are broken down into oxygen atoms (O) by strong ultraviolet rays from the sun, and these oxygen atoms react with oxygen molecules to produce ozone (03), which consists of three oxygen atoms.

The ozone layer in the stratosphere acts like a space suit that completely covers the earth. A loosening of the ozone layer can directly lead to a crisis of life on Earth.
