No one made chemicals to destroy the ozone. It was an unfortunate coincidence that many of them do harm it.
Man made chemicals are many. But the ones that were seen to destroy ozone were CFC's.
We have affected ozone layer by CFC's. These are man made chemicals that destroy ozone.
The chemicals that destroy the ozone layer are CFC's. These CFC's are cholorofluorocarbons which react with ozone to destroy it.
The CFC's are the ones destroy the ozone. They react with ozone and decompose it.
See "What is causing the depletion of the ozone layer?"
CFC are the chemicals that destroy the ozone layer. they react with ozone and decompose it.
Chlorofluorocarbons (CFCs), halons, and certain types of hydrochlorofluorocarbons (HCFCs) are human-made chemicals that cause ozone depletion. When these substances are released into the atmosphere, they break down and release chlorine and bromine atoms, which then destroy ozone molecules in the stratosphere.
CFC's are chemicals which can destroy ozone. The destruction is due to the reaction with ozone.
The chemicals that breakdown ozone are divided into classes. CFC's are the main ones that destroy it.
Chlorofluorocarbons (CFCs) and halons are types of chemicals known to destroy the ozone layer, which protects us from harmful ultraviolet light. These chemicals break down ozone molecules in the stratosphere, reducing the ozone layer's ability to shield us from UV radiation.
The ozone depletion is prevented by avoiding the use of CFC's. CFC's are the chemicals that destroy ozone.
CFC's are the destroyers of the ozone. These chemicals are the ones that could destroy ozone in clusters.
