FILE - A Thursday June 10, 2010 photo from files showing local health workers removing earth contaminated by lead from a family compound in the village of Dareta in Gusau, Nigeria. U.N. officials are warning that a lead poisoning outbreak that has killed more than 400 children in northern Nigeria has become "a neglected, underfunded emergency." The report released Friday Jan. 7, 2011 warns that the outbreak in Zamfara state remains an "alarming, continuing health risk" for an unknown number of villages in the rural area. The report says tests conducted by U.N. officials in September and October found lead levels in the air as high as 500 times the standard limit, while water and soil also were heavily contaminated. less
