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 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.
