CRTs contain a large amount of lead, which is a toxic heavy metal. When CRTs are disposed of in landfills, the lead can leach into the soil and water, contaminating the environment. In addition, CRTs are difficult to recycle because of the lead they contain.<\/p>\n<p>Floppy drives, hard drives, power supplies, and system boards do not contain lead and are therefore easier to dispose of environmentally. However, they can still contain other harmful materials, such as mercury and cadmium.
