Title
Accumulation, elimination and retention of (99)Tc by duckweed
Author
Abstract
This study deals with the accumulation dynamics of the long-lived fission product technetium ((99)Tc) in duckweed. Duckweed serves as model for aquatic plants, because of its representative foliar uptake for (99)Tc. This study shows that (99)Tc is irreversibly accumulated and distributed over cytoplasm, chloroplasts and mitochondria. Autoradiography showed that (99)Tc was not transported to new biomass. Irreversible storage of (99)Tc in plant biomass means that steady-state situations cannot be interpreted as a balance between uptake and elimination of (99)Tc, but that (99)Tc continuously builds up in each single duckweed plant and overall Tc concentrations are averaged over new biomass.
