Many of the dangerous chemicals we all want to eliminate from electronic products are found in very small amounts, but there’s one toxic substance that some companies still ship by the pound, and that’s the lead contained in their cathode-ray tube (CRT) displays. A typical CRT contains approximately 3 pounds (1.36 kg) of lead. In mid-2006, Apple became the first company in the computer industry to completely eliminate CRTs. The effect has been stunning — our first CRT-based iMac contained 484 grams of lead; our current third-generation LCD-based iMac contains less than 1 gram of lead.A typical CRT display contains 3 pounds of lead? Can that really be? If so, what an incredible statistic.
