Environmental Requirements
Brominated flame retardants
Brominated flame retardants are present in printed circuit boards, cables,
wires, casings and housings. In turn, they delay the spread of fire. Up to
thirty percent of the plastic in a computer casing can consist of flame
retardant substances. These are related to another group of
environmental toxins, PCBs, which are suspected to give rise to similar
harm, including reproductive damage in fisheating birds and mammals,
due to the bio-accumulative

processes. Flame retardants have been found in human blood and
researchers fear that disturbances in foetus development may occur.
TCO'95 demand requires that plastic components weighing more than 25
grams must not contain organically bound chlorine and bromine.
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
colour-generating layers of certain computer displays. Cadmium damages
the nervous

Bio-accumulative is defined as substances which accumulate within living organisms

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 colour-generating layers of
display screens must not contain any cadmium.
