Best Answer

1. CRT: contains lead and Mercury

2. Motherboard: contains silicon and copper

3. Hard disk

In addition, batteries (acid) and printer toner cartridges both require special handling for disposal.

CRTs (or monitors) contain around 4 pounds of lead, and environmental laws say they must be properly disposed of. Printer toner cartridges contain ink that can be poisonous in large quantities. Therefore, they should either be recycled by the company you bought them from or refilled at a local shop.
