摘要：
In the assessment of the environmental distribution of technetium (99 Tc) the transfer factor or bioconcentration factor is an important parameter.Generally the transfer factor is based on (pseudo) equilibria, first-orderuptake and elimination processes, and an absence of homeostatic control. Thepresent work evaluates the transfer factor concept for Tc in duckweed by evaluatingTc steady-state concentrations in duckweed against growth rate and nutrientconcentration. It was concluded that (1) Tc accumulation is not homeostaticallycontrolled and (2) the transfer factor is inversely proportional to the growthrate.
