effects, including reproductive damage in fisheating birds and mammals, due to
the bio-accumulative* processes. Flame re t a rdants have been found in human
blood and researchers fear that disturbances in foetus development may occur.
TCO'99 demand requires that plastic components weighing more than 25 grams
must not contain flame retardants with organically bound chlorine and bromine.
Flame retardants are allowed in the printed circuit boards since no substitutes are
available.
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'99 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'99 requirement states that batteries, the colourgenerating layers of display
s c reens 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 re q u i rement states that batteries may not contain any Merc u ry. It also
demands that no merc u ry is present in any of the electrical or electro n i c s
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.
*Bio-accumulative is defined as substances which accumulate within living
organisms.
**Lead, Cadmium and Merc u ry are heavy metals which are Bio-accumulative.
