13 february 2013 - Dandora dumpsite, Nairobi, Kenya - A Kenyan scavenger looks for metal scraps exposed by waste burning and methane fires at the edge of the Dandora dumpsite, one of the largest and most toxic in Africa. This activity can be lucrative for the scavengers, but the fires cause severe diseases. A study by the Nairobi-based U.N. Environment Programme (UNEP) found that half of 328 children tested around the site suffered from respiratory problems and had lead concentrations in their blood exceeding the internationally accepted level. Located near slums in the east of the Kenyan capital Nairobi, the open dump site was created in 1975 and covers 30 acres. The site receives 2,000 tonnes of unfiltered garbage daily, including hazardous chemical and hospital wastes. It is a source of survival for many people living in the surrounding slums, however it also harms children and adults' health in the area and pollutes the Kenyan capital.
