Data are presented on the uptake of P, S, Ca, Fe, Co, Zn, Ge, Rb, Sr, Y, Zr, Nb, Ru, I, Cs, and Ce isotopes by duck weeds, pond weed, crowfoot, aquatic plant, bladderwort, water thyme, and other fresh water plants and 17 types of marine organisms (leeches, snails, water bugs, crabs, carp hybrides, and tadpoles of lake frogs). A mean radioisotope uptake coefficient was determined for each individual plant and organism. Except for P and Sr the uptake by plants is higher than in organisms. All elements are separated into high and low uptake coefficient groups: high; P, Fe, Co, Zn, Y, Zr, Nb, and Ce; and low, S, Ge, I, and Cs. The plants show exceptionally high accumulation coefficients for Fe, Zn, Y, Nb, and Ce. Tests of EDTA (ethylenediaminetetraacetate or trilon B) effects on the uptake coefficient show sharp drops for Fe, Co, Zn, Y, and Ce uptake (10 to 100 fold). Somewhat smaller drops in uptake were observed for Ca, Zr, Nb, Ra, and I, while Rb, Sr, and Cs uptake increases. Uptake of the other elements was not affected. (R.V.J.)
