[email protected] Received: February 11, 2019; Accepted: March 25, 2019; Published: March 28, 2019 Abstract Normal relations between the United States and the Socialist Republic of Vietnam in 1995 permitted scientists, public health experts, and the media to visit Vietnam and assess the impact of the use of Agent Orange on the ecology and peoples of Vietnam. Evaluation of scientific data suggested that exposures to the toxic contaminant 2,3,7,8-Tetrachlorodibenzo-p-dioxin, TCDD, in 2,4,5-T-containing tactical herbicides sprayed on jungle forests and mangroves were minimal for Vietnamese located in villages near combat areas. Although some tactical herbicides were sprayed in rural areas, the largest sources of polychlorinated dioxins and furans (PCDD/Fs) were from biomass-burning, especially from municipal dumpsites. In urban areas, sources of PCDD/Fs were from industrial emissions. Measurable levels of PCDD/Fs in Vietnamese were in those residents associated with dioxin “hotspots”, specifically from former airbases where Agent Orange had been stored or loaded on US military aircraft. These hotspots were characterized by high soil and sediments levels of 2,3,7,8-TCDD that persisted in spill sites for over 50 years. Movement of low levels of PCDD/Fs into food sources were a continuing source of contamination for residents adjacent to hotspots.
