Explanation
CRT monitors contain significant quantities of hazardous materials, most notably lead oxide (up to 4–8 lbs of lead) embedded in the glass of the picture tube, as well as phosphor compounds, barium, and cadmium. These substances are toxic and classified as hazardous e-waste, requiring special disposal through certified recyclers rather than standard trash. While CRTs are heavy and the glass can break, the primary regulatory and environmental concern driving proper disposal is the hazardous chemical content - particularly the lead - not weight or breakage risk.
