Abstract

This reports the results of the cultivation of maize and beans in the open and enclosed in controlled conditions in pots containing 2,3,7,8-TCDD at concentrations between 1 and 752 ppt. The aim of the research was to establish the capacity of higher plants to absorb, transport, accumulate and possibly eliminate dioxin. The roots, which were analyzed after careful washing in running water and in some cases with n-hexane also, showed TCDD levels which were higher than those of the soil. The parts of the plants above ground however did not show a significant increase of TCDD as a function of time and with the increase in the concentration of pollution in the soil, while a significant contamination by evaporation of the TCDD from the soil seemed to be proved. Thus one may conclude that maize and beans have a high absorption of 2,3,7,8-TCDD in the roots, a transfer to the aerial parts through the roots limited to a few ppt for cultivation in soils contaminated up to 750 ppt and contamination of the aerial parts through the process of volatilization.
