The complainants comprise 143 members of the Roma, Ashkali, and Egyptian community in Kosovo who are, or have been, resident in five UNMIK administered camps for internally displaced persons (IDPs) throughout northern Mitrovica/Mitrovicë as well as three nongovernmental organization (NGO) employees working in the camps. All complainants claim to have suffered lead poisoning and other health problems on account of the soil contamination in the camp sites due to the proximity of the camps to the Trepca smelter and mining complex and/or on account of the generally poor hygiene and living conditions in the camps.
