Absence of Hg transpiration by shoot after Hg uptake by roots of six terrestrial plant species

摘要: In this paper we investigated if, and to what extent, six different plant species accumulate, translocate emit mercury (Hg) into the air. The Hg uptake by roots, distribution of shoot release via shoots garden pea, spring wheat, sugar beet, oil-seed rape, white clover willow were in a transpiration chamber. airborne was trapped Hopcalite trap or gold trap. Traps materials analysed for content CVAAS. results show that all able take up large extent from nutrient solution containing 200 microg L(-1) Hg. However, translocation low (0.17-2.5%) reached leaves no absorbed air detected.
