Environmental requirements
Flame retardants:
Flame retardants are present in printed circuit boards, cables, wires, casings
and housings. Their purpose is to prevent, or at least to delay, the spread of
fire. Up to 30% of the plastic in a computer casing can consist of flame
retardant substances. Most flame retardants contain bromine or chloride,
and those flame retardants are chemically related to another group of
environmental toxins, PCBs. Both the flame retardants containing bromine or
chloride and the PCBs are suspected of giving rise to severe health effects,
including reproductive damage in fish-eating 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.
The relevant TCO '99 demand requires that plastic components weighing
more than 25 grams must not contain flame retardants with organically
bound bromine or chlorine. Flame retardants are allowed in the printed
circuit boards since no substitutes are available.
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. The relevant TCO '99 requirement states that
batteries, the colour-generating layers of display screens and the electrical or
electronics components must not contain any cadmium.
