An organization of U.S. veterans claims that a significant portion of defoliants and herbicides that the U.S. provided for South Korea in late 1960s went unused.

The Korean War Project, a Web site for Korean War veterans, recently disclosed a U.S. government document showing that 111 tons of monuron, 51-thousand liters of Agent Orange, and 73-thousand liters of Agent Blue were allocated in 1968 and 1969 for regions under the control of the South Korean military.

Ted Barker, the head of the Web site, said that Agent Orange and Agent Blue were sprayed on a 15-point-three square kilometer area and 14-point-seven square kilometer area, respectively, using much smaller amounts than what was allocated in total.

Barker said that it means there were unused herbicides, hinting that the unused toxic herbicides were discarded in South Korea.
