E-WASTE MANAGEMENTE-WASTE MANAGEMENT

IntroductionE-waste is a popular, informal name

for electronic products nearing the end of their “useful life”.This includes

Computers and their peripherals Cell phones Photocopiers Digital cameras MP3 players .

Where does it come from?

Households and Small businessesLarge businesses, Institutions and

Governments

How big is the problem?

Problem continues………Electronic products often contain hazardous and toxic materials that pose environmental risks if they are land filled or incinerated.

Televisions, video and computer monitors use cathode ray tubes (CRTs), which have significant amounts of lead.

Printed circuit boards contain primarily plastic and copper, and most have small amounts of chromium, lead solder, nickel, and zinc.

Problem continues………

In addition, many electronic products have batteries that often contain nickel, cadmium, and other heavy metals. Relays and switches in electronics, especially older ones, may contain mercury.

Also, capacitors in some types of older and larger equipment that is now entering the waste stream may contain polychlorinated biphenyls (PCBs)

Effects of E-waste constituent on health

Sl no:

Sources of ewaste Constituent Health effects

1. Solder in printed circuit boards, glass panels and

gaskets in computer monitors

Lead (PB)

•Damage to central and peripheral nervous systems, blood systems and kidney damage. •Affects brain development of children.

2.Chip resistors and semiconductors Cadmium (CD)

•Toxic irreversible effects on human health. •Accumulates in kidney and liver. •Causes neural damage.

Sl no: Sources of ewaste Constituent Health effects

3. Cabling and computer housing

Plastics including PVC

Burning produces dioxin. It causes •Reproductive and developmental problems; •Immune system damage;

4. Front panel of CRTs Barium (Ba)

Short term exposure causes:•Muscle weakness; •Damage to heart, liver and spleen.

5. Motherboard Beryllium (Be)

•Carcinogenic (lung cancer) •Inhalation of fumes and dust. Causes chronic beryllium disease or beryllicosis. •Skin diseases such as warts.
