What is the main environmental risk of improper refrigerant disposal?

The primary environmental risk associated with improper refrigerant disposal is harm to human health and the environment. Refrigerants, especially those that are ozone-depleting substances (ODS) or high global warming potential (GWP) gases, can contribute to serious environmental issues if not disposed of correctly.

When refrigerants are released into the atmosphere, they can deplete the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation. This depletion can lead to increased UV exposure, resulting in higher rates of skin cancer, cataracts, and other health problems in humans, as well as adverse effects on wildlife and ecosystems. Additionally, certain refrigerants are potent greenhouse gases that can contribute significantly to climate change when emitted.

Proper disposal practices, including recycling and recovery of refrigerants, are essential to mitigate these risks and ensure environmental safety. The other options, while important in their own contexts, do not directly address the immediate and harmful impacts on environmental and human health caused by improper refrigerant disposal.
