STUDI RELATIVI ALL'ASSUNZIONE DI TCDD DA PARTE DI ALCUNE SPECIE VEGETALI
Maize and bean plants grown under controlled conditions in pots located in greenhouses are here considered. The goal of the work was the evaluation of the amount of dioxin transferred to the vegetation from soils doped with TCDD in the range of concentration from 1 to 250 ppt. The results can be summarized as follows: - after 75 days there is an increase of TCDD concentration in the soil around the roots (2 or 3 times) - in the roots the TCDD concentration is at least equal to that of the soil at the beginning of the experiment - the TCDD translocation from roots to the plants is limited (range of concentration 10-40 ppt and 1-4 ppt for dry and fresh material respectively) and it is probably related to the solubility of dioxin in the water adsorbed by the plants.
