Question: What is the primary environmental concern associated with the release of HFC refrigerants like R-410A into the atmosphere?
Answer options:
- They deplete the ozone layer.
- They contribute significantly to acid rain. ✅ They are potent greenhouse gases that contribute to climate change.
- They are highly toxic to aquatic life.
Correct answer: They are potent greenhouse gases that contribute to climate change.
Explanation: HFCs (hydrofluorocarbons) do not deplete the ozone layer; however, they have a high Global Warming Potential (GWP), meaning they are potent greenhouse gases that trap heat in the atmosphere, significantly contributing to climate change and thus heavily regulated.
