The children were born with physical and mental disabilities that the center's director said were caused by their parents' exposure to the chemical dioxin in the defoliant Agent Orange. Washington was slow to respond, but on Thursday, Aug. 9, 2012 the U.S. for the first time will begin cleaning up leftover dioxin that was stored at the former military base, now part of Danang's airport.

Agent Orange cleanup begins in Vietnam

August 12, 2012

Dioxin, a persistent chemical linked to cancer, birth defects and other disabilities, has seeped into Vietnam's

soils and watersheds, creating a lasting war legacy that remains a

thorny issue between the former foes. Washington has been slow to

respond, but on Aug. 8 the U.S. for the first time will begin cleaning up dioxin from Agent Orange that was stored at the former military base, now part of Danang's airport.
