15toxins, PCBs, which are suspected to give rise to similar harm, including reproductive damage infisheating birds and mammals, due to the bio-accumulative* processes. Flame retardants havebeen found in human blood and researchers fear that disturbances in foetus development mayoccur.TCO’95 demand requires that plastic components weighing more than 25 grams must not containorganically bound chlorine and bromine.Lead**Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages thenervous system and in higher doses, causes lead poisoning.TCO’95 requirement permits the inclusion of lead since no replacement has yet been developed.Cadmium**Cadmium is present in rechargeable batteries and in the colourgenerating layers of certaincomputer displays. Cadmium damages the nervous system and is toxic in high doses.TCO’95 requirement states that batteries may not contain more than 25 ppm (parts per million) ofcadmium. The colourgenerating layers of display screens must not contain any cadmium.Mercury**Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous systemand is toxic in high doses.TCO’95 requirement states that batteries may not contain more than 25 ppm (parts per million) ofmercury. It also demands that no mercury is present in any of the electrical or electronicscomponents concerned with the display unit.CFCs (freons)CFCs (freons) are sometimes used for washing printed circuit boards and in the manufacturing ofexpanded foam for packaging. CFCs break down ozone and thereby damage the ozone layer inthe stratosphere, causing increased reception on Earth of ultraviolet light with consequent increasedrisks of skin cancer (malignant melanoma).The relevant TCO’95 requirement; Neither CFCs nor HCFCs may be used during the manufacturingof the product or its packaging.*Bio-accumulative is defined as substances which accumulate within living organisms.**Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.To obtain complete information on the environmental criteria document, order from:TCO Development UnitS-114 94 StockholmSWEDENFAX Number: +46 8 782 92 07E-mail (Internet): development@tco.seYou may also obtain current information on TCO’95 approved and labelled products byvisiting their website at: http://www.tco-info.com/78133521 5/15/98, 2:16 PM17
