The toxicity of CFCs is due to their ability to reacts with the ozone molecules found in the stratosphere resulting in the depletion of the ozone layer.
CFCs are the short name or acronyms for the chemicals known as chlorofluorocarbons.
These are chemicals which have been used as refrigerants in the past because of their non-toxicity as well other useful properties which makes them good as refrigerants.
However, despite being non-toxic, when CFCs are released into the atmosphere and reach the stratosphere layer of the atmosphere, they have been found to be toxic. Their toxicity is due to their ability to reacts with the ozone molecules found in the stratosphere.
This reaction with ozone molecules in the ozone layer results in the depletion of the ozone layer.
In conclusion, CFCS are chemicals which are used as refrigerants. The are non-toxic but become toxic by degrading the ozone layer of the atmosphere.
