Vietnam's latest study on Agent Orange/dioxin has reaffirmed the long-lasting effects caused by the toxic chemical on human health and the environment.

 

Assistant Professor, Doctor Nguyen Van Tuong from the Hanoi Medical University said that a recently-conducted study of researchers from medical universities across the country indicated that residue of dioxin is still found at high levels in the environment in some "hot" areas, including Da Nang Airport in central Da Nang city, Bien Hoa Airport in southern Dong Nai province, and Nam Dong area in central Thua Thien-Hue province.

 

The study, which focuses on the variation in some biological factors, such as genetics, immunology, biochemistry and haematology in groups of people at high risk of exposure to dioxin, also found that the rate of disorder in lymphocyte form in the high-risk group in Bien Hoa is 59 percent and in Nam Dong, 24.7 percent, as compared with only 2.6 percent in the group which had no contact with AO/dioxin during and after the war in the northern port city of Hai Phong.

 

Research conducted among veterans who fought on the southern battlefield during the war and now live in Hanoi's Cau Giay district, found that there was a marked level of 2,3,7,8 TCDD, one of the most potent toxic dioxins, in their blood and a high rate of mental, respiratory and dermatological disease.

 

Dr. Tuong said that tests for the research were conducted at the Analysis and Experiment Service Centre in Ho Chi Minh City and the Fukuoka Institute of Health and Environmental Sciences of Japan. He added that he would report the results of the study on behalf of the research team at an international conference on dioxin which is scheduled for August in Norway.
