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 today there 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.
