The relevant TCO’99 demand requires that plastic components weighing

more than 25 grams must not contain flame retardants with organically

bound bromine or chlorine. Flame retardants are allowed in the printed

circuit boards since no substitutes are available.

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. The relevant TCO’99 require-

ment states that batteries, the colour-generating layers of display

screens and the electrical or electronics components must not contain

any cadmium.

Mercury**

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

damages the nervous system and is toxic in high doses. The relevant

TCO’99 requirement states that batteries may not contain any mercury.

It also demands that mercury is not present in any of the electrical or

electronics components associated with the labelled unit.

CFCs (freons)

The relevant TCO’99 requirement states that neither CFCs nor HCFCs

may be used during the manufacture and assembly of the product.

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

CFCs break down ozone and thereby damage the ozone layer in the

stratosphere, causing increased reception on earth of ultraviolet light

with e.g. increased risks of skin cancer (malignant melanoma) as a

consequence.

Lead**

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

tors. Lead damages the nervous system and in higher doses, causes

lead poisoning. The relevant TCO’99 requirement permits the inclusion

of lead since no replacement has yet been developed.

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

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