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.

inclusion of lead since no replacement has yet been developed.
