Mercury is a heavy metal that is Bioaccumulative.
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.
