Study alludes to deformaties from dioxin in Vietnam
Article Abstract:
Canada-based Hatfield Consultants Ltd. has conducted a study of the effects of dioxin left from the spraying of Agent Orange in Vietnam, that concludes that the pesticide is causing serious human harm. The study compares heavily sprayed areas with areas where the defoliant was not sprayed. Human blood samples, livestock, poultry, fish and agricultural crops showed high dioxin levels in areas that had been heavily sprayed. Although the study shows connections between dioxin exposure and human birth defects, Vietnamese doctors disagree as to the proponderance of deformaties, and some have noticed the prevalence of cancer.

Scientists challenge EPA methods for assessing dioxin cancer risk
Article Abstract:
An analytical tool suggested for the assessment of cancer risk from dioxin exposure has been rejected by top scientists and risk experts. They contend that the methodology, based on a dose metric called area-under-the-curve, has been proven to be inadequate in the EPA's draft dioxin reassessment. They also say that a single analytic tool should not be used in conducting risk assessments. According to its supporters, however, the methodology yields more accurate calculations which show that dioxin is not as great a cancer risk as EPA claims.

The U.S. dioxin inventory: are there missing sources?
Article Abstract:
Studies have shown that environmental dixon levels are far in excess of known emissions. These findings suggest that there are unknown sources of dioxin or that scientists have underestimated natural sources. Efforts to account for dioxin emissions have improved over the years but more research needs to be conducted to gain a more accurate picture of the behavior of dioxins.
