What does improper disposal of e-waste release?

Explanation:
Improper disposal of e-waste mainly risks releasing toxic metals into the environment. Electronics contain hazardous materials such as lead, mercury, and cadmium. When discarded carelessly—especially dumped in landfills or burned—these substances can leach into soil and groundwater, causing long-term contamination and health risks. That’s why the option describing toxic metals entering landfill sites best captures the main consequence. The other options don’t fit: harmless gases aren’t the typical, sustained outcome of improper disposal, disposal doesn’t reduce battery efficiency, and it certainly doesn’t increase soil fertility.
