HUMAN ADIPOSE-TISSUE DIOXIN AND DIBENZOFURAN LEVELS AND DIOXIN TOXIC EQUIVALENTS IN PATIENTS FROM THE NORTH AND SOUTH OF VIETNAM

Sixty patients at hospitals in the north and south of Vietnam had adipose tissue dioxin (TCDD only or PCDD/F) analysis performed, 50 as individual TCDD or PCDD/F analyses, and 10 from the north in a pooled sample analysis. Dibenzodioxin and dibenzofuran adipose tissue levels are usually higher in persons from the south of Vietnam than in persons in the north. There is also a direct correlation between human age and PCDD/F levels. However, dibenzofurans, unlike dioxins, do not differ between persons from the north and south of Vietnam. Vietnam provides an opportunity for human health effects studies of PCDD/F exposure. © 1990.
