A boy burns cables from computers and other electronic equipment in order to retrieve copper, at Agbogbloshie dump, which has become a dumping ground for computers and electronic waste from all over the developed world. Hundreds of tons of e-waste end up here every month. It is broken apart, and those components that can be sold on, are salvaged. Burning creates some of the most carcinogenic and toxic substances known, including polycyclic aromatic hydrocarbons, dioxins and furans, as well as releasing toxic metals such as lead, beryllium and cadmium. At theses burning sites concentrations of toxic metals have been found at over one hundred times the normal level. Children do not wear any protective clothing and so expose themselves to lethal doses of these hazardous chemicals.
