| 摘 要： | 在试验室条件下研究了Oryzias latipes鱼体对不同形态轻稀土La的积累特征及它对游离La吸收的动力学过程，并初步探讨了鱼对La的吸收机制。结果表明，试验鱼对La的积累量随水相游离La浓度增高、暴露时间增长而增加；水相富里酸的存在明显降低了La对鱼对生物有效性。此外，试验鱼也可以通过摄食获取水相中的La。 |

| Abstract: | The accumulation and absorption kinetics of La by fish (Oryzias latipes) from both water and food were tested in fresh water. The effects of La concentration in water and food and the existence of fulvic acid on the absorption were investigated. It is demonstrated that the amount of La accumulated in both fish and gill increases with the increase of La concentration in water and food and exposure duration up to a level above which the normal physiological activity of fish is inhibited. With fulvic in the system, the absorption rate decreases significantly indicating that the fulvic combined La is not available to the fish uptake. |
