Summary
Maize and bean plants grown on soil polluted with3H-2,3,7,8-tetrachlorodibenzo-p-dioxin (3H-TCDD) accumulated the toxin in the aerial parts progressively with the time and with the soil contamination. Plants in hydroponic solution polluted with3H-TCDD accumulated the toxin in the aerial parts in the light and not in the dark; the concentration of TCDD accumulated was not proportional to the surface area of plant organs; the distribution of3H-TCDD in the leaves suggested that TCDD was translocated through the vessels to the aerial parts by the transpiration stream.
