Abstract

Volatilization of 2,3,7,8-TCDD from soil and resorption on foliage represents a significant route of contamination. ome studies indicate low-level uptake, translocation from roots to foliage and transpiration from foliage, while one shows more than 95% of 2,3,7,8-TCDD associated with edible fruits and with tubers is found in peels. ifferences in bioavailability from different soils might account for some inconsistencies between existing studies, suggesting additional information useful in reporting future work.
