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.
TCO'95 requirement permits the inclusion of lead since no replacement has yet been developed.
Cadmium**
Cadmium is present in rechargeable batteries and in the colourgenerating layers of certain computer displays.
Cadmium damages the nervous system and is toxic in high doses.
TCO'95 requirement states that batteries may not contain more than 25 ppm (parts per million) of cadmium. The
colourgenerating layers of display screens must not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous system and is toxic
in high doses.
TCO'95 requirement states that batteries may not contain more than 25 ppm (parts per million) of mercury. It also
demands that no mercury is present in any of the electrical or electronics components concerned with the display
unit. 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 avail-
able.
CFCs (freons)
CFCs (freons) are sometimes used for washing printed circuit boards and in the manufacturing of expanded foam
for packaging. CFCs break down ozone and thereby damage the ozone layer in the stratosphere, causing in-
creased reception on Earth of ultraviolet light with consequent increased risks of skin cancer (malignant mela-
noma).
The relevant TCO'95 requirement; Neither CFCs nor HCFCs may be used during the manufacturing of the product
or its packaging.
* Bio-accumulative is defined as substances which accumulate within living organisms.
** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
