Up to 30% of the plastic in acomputer casing can consist of flame retardant substances. Most flame retardants containbromine or chloride, and those flame retardants are chemically related to another group ofenvironmental toxins, PCBs. Both the flame retardants containing bromine or chloride and thePCBs are suspected of giving rise to severe health effects, including reproductive damage infish-eating 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.The relevant TCO'99 demand requires that plastic components weighing more than 25 gramsmust not contain flame retardants with organically bound bromine or chlorine. Flame retardantsare allowed in the printed circuit boards since no substitutes are available.Cadmium**Cadmium is present in rechargeable batteries and in the colour-generating layers of certaincomputer displays. Cadmium damages the nervous system and is toxic in high doses. Therelevant TCO'99 requirement states that batteries, the colour-generating layers of displayscreens and the electrical or electronics components must not contain any cadmium.Mercury**Mercury is sometimes found in batteries, relays and switches. It damages the nervous systemand is toxic in high doses. The relevant TCO'99 requirement states that batteries may notcontain any mercury. It also demands that mercury is not present in any of the electrical orelectronics components associated with the labelled unit. There is however one exception.Mercury is, for the time being, permitted in the back light system of flat panel monitors as todaythere is no commercially available alternative. TCO aims on removing this exception when aMercury free alternative is available.CFCs (freons)The relevant TCO'99 requirement states that neither CFCs nor HCFCs may be used during themanufacture and assembly of the product. CFCs (freons) are sometimes used for washingprinted circuit boards. CFCs break down ozone and thereby damage the ozone layer in thestratosphere, causing increased reception on earth of ultraviolet light with e.g. increased risksof skin cancer (malignant melanoma) as a consequence.Lead**Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages thenervous system and in higher doses, causes lead poisoning. The relevant TCO'99 requirementpermits the inclusion of lead since no replacement has yet been developed.TCO'03-Ecological requirements for personal computers (TCO'03 applied model only)Congratulations!The display you have just purchased carries the TCO'03 Displays label. This means that yourdisplay is designed, manufactured and tested according to some of the strictest quality andenvironmental requirements in the world. This makes for a high performance product, designedwith the user in focus that also minimizes the impact on our natural environment.Some of the features of the TCO'03 Display requirements:ErgonomicsGood visual ergonomics and image quality in order to improve the working environment for theuser and to reduce sight and strain problems. Important parameters are luminance, contrast,resolution, reflectance, colour rendition and image stability.
