|Each computer or television display... contains an average of 4 to 8 pounds of lead. The total amount of lead in the 315 million computers that will become obsolete between 1997 and 2004 is estimated to be more than 1.2 billion pounds.
Lead can cause damage to the central and peripheral nervous systems, blood system and kidneys in humans. Lead accumulates in the environment, and has highly acute and chronic toxic effects on plants, animals and microorganisms. Children suffer developmental effects and loss of mental ability, even at low levels of exposure.
