Answer :
Final answer:
The accurate statement is that small appliance refrigerant leaks contribute to ozone depletion and global warming. Older CFC refrigerants damaged the ozone layer, while modern HFCs are potent greenhouse gases that contribute to climate change and can cause health risks. So the correct option is C.
Explanation:
The correct option is: C) Small appliance refrigerant leaks contribute to ozone depletion and global warming. Historically, the use of substances such as Freons, which are chlorofluorocarbons (CFCs), has been linked to the destruction of the Earth's ozone layer. The ozone layer plays a pivotal role in filtering out harmful ultraviolet radiation from the sun's rays. While newer refrigerants like hydrofluorocarbons (HFCs) do not contribute to ozone depletion, they are nonetheless potent greenhouse gases. Greenhouse gases trap heat in the atmosphere, contributing to global warming. Moreover, refrigerants can cause negative health impacts and increase the risk of respiratory illnesses.
It's important to note that leaks of refrigerants occur throughout the lifecycle of an appliance and have been addressed by regulations that ban the release of ozone-depleting substances during service, maintenance, and disposal. However, despite efforts to identify safe and effective alternatives to these substances, the continued use and emission of HFCs and other refrigerants have environmental and health-related consequences.
