Mercury**
Mercury is sometimes found in batteries, relays and switches and back-
light system. 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 except the back-light system.
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 increased reception on Earth of ultraviolet light with consequent
increased risks of skin cancer (malignant melanoma).
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.
