Dioxin Levels In Adipose Tissues Of Hospitalized Women Living In The South Of Vietnam In 1984-89 With A Brief Review Of Their Clinical Histories
WOMEN & HEALTH(1990)
摘要
Agent Orange, a phenoxyherbicide consisting of 50% 2,4-D and 50% 2,4,5-T, the latter contaminated in the parts per million range with the highly toxic dioxin, 2,3,7,8-TCDD, was sprayed in the south of Vietnam from 1962 to 1971. The chemicals are of concern because of their potential to be causally involved in cancer, adverse reproductive outcomes, immune deficiency and other illness. Because exposed women would be especially involved in the adverse reproductive outcomes, specifically spontaneous abortions and congenital malformations, as well as developmental deficiencies in children, we elected to conduct a pilot study in Vietnam to determine whether elevated 2,3,7,8-tetrachloro-p-dioxin-(TCDD), the dioxin characteristic of Agent Orange could still be found in some women between one and two decades after exposure, and whether the types of illness characteristic of dioxins was present in women with elevated dioxin levels. We were easily able to find some women with increased TCDD from Agent Orange, A surprisingly high level of dioxins from industrial sources was also found in these women in the south. Much lower levels of all dioxins were found in patients in the north of Vietnam. No obvious relation between elevated dioxins and disease was noted in this pilot study, which is meant to precede epidemiology studies which will test the hypotheses that elevated dioxins in humans may lead to an increase in adverse reproductive outcomes and in rates of certain cancers.
