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.
TCO‘99 requirement states that batteries, the colourgenerating 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, Mercury
damages the nervous system and is toxic in high doses.
TCO‘99 requirement states that batteries may not contain any Mercury. It
also demands that no mercury is present in any of the electrical or
electronics components associated with the display unit.
CFCs (freons)
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 consequent increased risks of skin cancer (malignant melanoma).
The relevant TCO‘99 requirement; Neither CFCs nor HCFCs may be
used during the manufacturing and assembly of the product or its
packaging.
