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

colourgenerating 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 colourgenerating layers of

display screens must not contain any cadmium.

Mercury**

Mercury is sometimes found in batteries, relays and switches and back-

light system. Mercury damages the nervous system and is toxic in high

doses.

TCO’95 requirement states that batteries must 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 except the back-light system.

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 damagethe ozone layer in the stratosphere,

causing increased ultraviolet light to enter the earth‘s atmosphere with

consequent increased risks of skin cancer (malignant melanoma).

The relevant TCO’95 requirement: Neither CFCs nor HCFCs may be

used during the manufacturing of the product or its packaging.

* Bio-accumulative is defined as substances which accumulate within living organisms.

** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
