Objectives: To assess levels of dioxin in food and human blood and determine the relationship between levels of dioxin in food and human blood in some areas of Vietnam. Subjects and method: A cross-sectional study on 108 human blood samples including males and females, 33 samples of chicken, 33 samples of pork and 33 samples of fish were collected at 33 sites in 16 provinces. | JOURNAL OF MILITARY PHARMACO-MEDICINE N09-2017 RELATIONSHIP BETWEEN LEVELS OF DIOXIN IN FOOD AND BLOOD IN SOME AREAS OF VIETNAM Vu Tung Son*; Doan Huy Hau* Vu Chien Thang*; Ha The Tan* SUMMARY Objectives: To assess levels of dioxin in food and human blood and determine the relationship between levels of dioxin in food and human blood in some areas of Vietnam. Subjects and method: A cross-sectional study on 108 human blood samples including males and females, 33 samples of chicken, 33 samples of pork and 33 samples of fish were collected at 33 sites in 16 provinces. Samples were then quantified with high resolution gas chromatography mass spectrometry (HRGC/HRMS) by the . EPA 1613 B. Result: Levels of dioxin in blood in the sprayed area was ( pg/g lipid) higher than in the unsprayed area ( pg/g lipid) with p .
