Appendix
Environmental Labelling of Personal Computers
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 requirement
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. There is however one
exception. Mercury is, for the time being, permitted in the back light
system of flat panel monitors as there today is no commercially available
alternative. TCO aims on removing this exception when a mercury free
alternative is available.
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
capacitors. 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.
