"Iraq's environmental problems - among world's worst - range from a looted nuclear site which needs cleaning up to sabotaged oil pipelines, a U.N. official said"

"Chemicals are seeping into groundwater and the situation is becoming worse and creating additional health problems,"

"Lack of spare parts and Iraq's inability to maintain pollution standards during two previous wars and more than a decade of crushing sanctions have damaged the environment, including the Tigris and Euphrates rivers where most of Iraq's sewage flows untreated."

"The situation became worse after the 2003 U.S.-led invasion, in which depleted uranium munitions were used against Iraq for the second time and postwar looting and burning of the once formidable infrastructure caused massive spills and toxic plumes"
