Environmental Requirements

Brominated flame retardants are present in printed circuit boards, cables,

wires, casings and housings. In turn, they delay the spread of fire. Up to

thirty percent of the plastic in a computer casing can consist of flame

retardant substances. These are related to another group of environmental

toxins, PCBs, which are suspected to give rise to similar harm, including

reproductive damage in fish eating birds and mammals, due to the

bioaccumulative processes. Flame retardants have been found in human

blood and researchers fear that disturbances in foetus development may

occur.

TCO'95 demand requires that plastic components weighing more

than 25 grams must not contain organically bound chlorine and

bromine.

Lead

Lead can be found in picture tubes, display screens, solders and

capacitors. Lead damages the nervous system and in higher doses,

causes lead poisoning.

TCO'95 requirement Permits the inclusion of lead since no

replacement has yet been developed.

Cadmium

Cadmium is present in rechargeable batteries and in the colour generating

layers of certain computer displays. Cadmium damages the nervous

system and is toxic in high doses.

TCO'95 requirement states that batteries may not contain more than

25 ppm (parts per million) of cadmium. The colour-generating layers

of display screens must not contain any cadmium.

Mercury

Mercury is sometimes found in batteries, relays and switches. Mercury

damages the nervous system and is toxic in high doses.

TCO'95 requirement states that batteries may not contain more than

25 ppm (parts per million) of mercury. It also demands that no

mercury is present in any of the electrical or electronics components

concerned with the display unit.

CFCs (freons)

CFCs (freons) are sometimes used for washing printed circuit boards and

in the manufacturing of expanded foam for packaging. CFCs break down

ozone and thereby damage the ozone layer in the stratosphere, causing

increased reception on Earth of ultraviolet light with consequent increased

risks of skin cancer (malignant melanoma).
