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 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
