| Abstract: | The absorption of 125 I and 3H in four aquatic plants was studied by solution cultivation. The results showed that arrowhead (Sagittaria pygmaea Miq.) was the fastest in absorbing 125 I among the four tested aquatic plants and its concentration factor for 125 I was the highest (85 79). The alligator alternanthera (Alternanthera philoxeroides) was the slowest in absorbing 125 I and its concentration factor was the lowest.However, the absorption of 3H in alligator alternanthera was the fastest among the four aquatic plants. After being absorbed by aquatic plants, the 125 I could be transfered to the shoot. In arrowhead, about 75% of 125 I remained in the root, 25% being transfered to the shoot. |
