Cadmium**
Cadmium is present in rechargeable batteries and in the colourgenerating layers of certain computer displays. Cadmium damages the nervous system and is toxic in high doses.
TCO’ 99 requirement states that batteries, the colourgenerating layers of display screens and the electrical or electronics components must not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous system and is toxic in high doses.
TCO’ 99 requirement states that batteries may not contain any Mercury. It also demands that no mercury is present in any of the electrical or electronics components associated with the display unit.
CFCs (freons)
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 consequent increased risks of skin cancer (malignant melanoma).
The relevant TCO’ 99 requirement; Neither CFCs nor HCFCs may be used during the manufacturing and assembly of the product or its packaging.
