CFCs (freons)
The relevant TCO'99 requirement states that neither CFCs nor HCFCs may
be used during the manufacture and assembly of the product. 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 e.g. increased risks of
skin cancer (malignant melanoma) as a consequence.
**
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. The relevant TCO´99 requirement permits the inclusion of lead
since no replacement has yet been developed.
**
Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
