From: A GIS study of dioxin contamination in a Vietnamese region sprayed with herbicide
Overlaid GPS data for breast-milk, soil and sediment samples in Cam Chinh. The primary agent used (about 65% of the herbicides) was called Agent Orange, which was a 50:50 mixture of 2,4-D and 2,4,5-T. Agent Orange was only one of several herbicide mixtures used during Operation Ranch Hand during the Vietnam War. Lesser amounts of Agent Purple (2,4-D and 2,4,5-T), Pink (2,4,5-T), Green (2,4,5-T), white (2,4-D plus picloram) and Blue (caccodylic acid) were applied. The 2,4,5-T in Agents Purple, Pink, Green and Orange was, unfortunately, contaminated with varying levels of dioxins [2]
