Regulatory Information
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 labeled 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.
