采用水培的方式研究了几种水生植物对１２５Ｉ和３Ｈ的吸收，结果表明，供试的４种水生植物中，矮慈姑（ＳａｇｉｔａｒｉａｐｙｇｍａｅａＭｉｑ．）对水体中１２５Ｉ的吸收最快，富集系数最大，到试验结束时达８５７９。螃蜞菊（Ａｌｔｅｒｎａｎｔｈｅｒａｐｈｉｌｏｘｅｒｏｉｄｅｓ）对１２５Ｉ的吸收最慢，富集系数最小，但螃蜞菊对３Ｈ的吸收却是４种植物中最快的。植物吸收１２５Ｉ后，能运转至地上部，矮慈姑中约有７５％的１２５Ｉ滞留于根部，２５％运转到地上部。数学模拟结果表明，１２５Ｉ和３Ｈ在水生生态系统中的动态变化遵循Ｙ＝Ａｅｂｔ的变化规律。
Hydroponics was used to study the uptake of 125 I and 3H by several aquatic plants. The results showed that among the four aquatic plants tested, Sagitaria pygmaea Miq. Had the fastest absorption and the highest enrichment coefficient for 125 I, By the end of the experiment up to 85 79. Alternantheraphiloxeroides had the slowest absorption and the lowest enrichment coefficient for 125I, but the absorption of 3H by crabgrass was the fastest among the four plants. After the plant has absorbed 125 I, it can run to the aerial part, and about 75% of the short sturdy 125 I remain in the root and 25% in the aerial part. Mathematical simulation results show that the dynamic changes of 125I and 3H in aquatic ecosystem follow the rule of Y = Aebt.
