Cadmium phosphide (Cd3P2) is a semiconductor compound with potential environmental impacts due to the toxicity of cadmium and its use in electronic devices and photovoltaic cells.

Exposure to cadmium can cause various adverse health effects, including kidney damage, lung damage, and cancer. Additionally, the production and disposal of cadmium-containing products can lead to pollution of air, water, and soil.

Specifically, the environmental impact of cadmium phosphide depends on how it is used and disposed of. In electronic devices, such as LEDs and solar cells, cadmium phosphide is typically encapsulated or otherwise contained to prevent exposure to humans or the environment. However, improper disposal of these devices can lead to leaching of cadmium into soil and groundwater.
