 note = {Insolubilization patterns of technetium (Tc) and other trace elements (Sc, Co, Zn, Se, Rb, Sr, Y, Nb, Ce, Pm, Gd, Lu, Hf, and Re) in surface water covering paddy fields were compared to gain insight into the behavior of Tc in an agricultural environment.The insolubilization of Tc, which did not pass through a 0.2-lm-pore-size filter, was mainly caused by bacteria.Among the 14 other elements investigated, Nb was insolubilized by bacteria and the amounts of insoluble Nb were positively correlated with those of Tc.Although Re is a chemical analog of Tc, no similarity was observed.These results suggest that Tc behaves similarly to Nb in the  insolubilization in surface water covering paddy fields.},
