| Abstract: | The isotope tracer techniques for simulated pollutants are applied to explore the effect of stable isotopic carrier on green vegetable absorption 141 Ce. The results showed that concentration of 141 Ce in the green vegetable and its each parts and quantity of isotopic carrier follows linear negative interrelaton. The concentration of 141 Ce in the each parts of green vegelable was: root>part overground, the part overground was: withered yellow leaf>older leaf>tender leaf. |
