Environmental requirements
Flame retardants
Flame retardants are present
in printed circuit boards, cables, wwes, casings and housings Their
purpose is to preverr~ or at least to delay the spread of tire. 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 ofenwronmental toxins, PCBS. Both the flame
retardants contain ing bromine or chloride and the PCBS are suspected of giving rise to severe health
effects, nrcludlng 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
foeicrs development may occur
The relevant TC099 demand requires that plastic components weighing more than 25 grams must not
contain flame retardants with orgarrlcally 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 m high doses. The relevant TC099
requirement states that batter] es, the colour-generating layers of dmplay screens and the electrical or
electronics components must not contain any cadmium.
Mercurya"
Mercury is sometimes found in batteries, relays and switches. It damages the nervous system and is
toxic in high doses The relevant TC099 requwement states that batteries may not contain any mercury
It also demands that mercury is not present in any of the electrical or electronics components associated
with the Iabelled unit There is however one exception. Mercury is, for the hme being, permmed in the
back I]ght system of flat panel monitors as there today is no commercially available alternative TCO
alms on remowng this exception when a mercury free alternative IS avadable.
CFCS (freons)
The relevant TC099 requirement states that neither CFCS rror
HCFCS may
be used

Increased reception on earth of ultrawolet light with e g. increased risks of sk}rr cancer (mallgnant
melanoma) as a consequence
Lead'"
Lead can be found in picture tubes, display screens. solders and capac]lors. Lead damages k nervous
system and m higher doses, causes lead poisoning. The relevant TCO '99 requirement permits the
irrclus]on of lead stnce no replacement has yet been developed.
