There were other ”Rainbow Herbicides” used. We are told that ”Agent Orange” didn’t start shipping until 1965. That being true, means Panama, Vietnam and Thailand received ”Agent Purple” 1958-1964, which according to the experts, would have had a much higher content of dioxin, known as Agent Purple.
…generally, agents produced earlier, such as Purple and Pink suffered from higher levels of contamination. A 2003 Nature paper by Stellman et al., which re-apprised the average TCDD content of Agent Orange from the 3 ppm that USAF had reported to a level of 13 ppm, also estimated that Agent Purple may have had 32.8 ppm of TCDD on average. A sample of Agent Purple archived at Eglin Air Force Base had an even higher content of 45 ppm TCDD.[8]
