| Abstract | The collection and management of waste electrical and electronic appliances around the world, and the possible negative environmental consequences have been an issue of current debate. Cathode ray tubes {(CRTs)} used as display screen for computer monitors and televisions contains large quantities of lead, estimated at between 0.5 and 4�kg, depending on the size of the {CRT} and has been identified as the most polluting of all electronic waste components. Having failed the tests used in the toxicity characterization of solid wastes, {CRTs} have been declared [`]hazardous' and subsequently banned from landfills and incinerators in most developed countries. Presently, large quantities of {CRTs} are generated globally with only few developed countries having effective take back and sound management program. Meanwhile, large quantities of {CRT-containing} devices are being moved across frontiers into developing countries in the name of [`]reuse' and [`]bridging the digital divide'. With near absence of recycling infrastructure for electronic wastes in most developing countries, waste {CRTs} are disposed of with {MSW} at open dumps and unsanitary landfills. This paper reviews the current practices in the management of {CRTs} around the world, with emphasis on the role of regulations, availability of recycling infrastructure, recycling/reuse routes, and export into developing countries. Inappropriate disposal of waste {CRTs} creates the opportunity for large-scale environmental contamination with heavy metals, especially lead. Appropriate disposal routes are required globally in the management of {CRTs} in order to mitigate environmental contamination and human exposure to toxins. |
