Serum 2,3,7,8-Tetrachloro-dibenzo-p-dioxin Levels of New Zealand Pesticide Applicators and Their Implication for Cancer Hypotheses

Abstract

On the basis of our findings in these subjects in New Zealand, we conclude that increased risks of cancer from brief exposure to phenoxyherbicides reported in other countries are probably not attributable to the TCDD that contaminates 2,4,5-T. We cannot determine from these results, however, whether TCDD exposure from prolonged use of 2,4,5-T poses significant health risks.
