This may be due to hydrolytic chelating, precipitation and the sediment or hydrobioes attachment, absorption etc. The honewort had stronger ability of accumulating La because of its large leaf surface that could attach La. The accumulating ability of snail and fish to La was relatively weaker but some organs of them had higher contents of La especially in the intestines, shell of snail, and in gill, internal organs, scales, head, bone of fish, rare in muscle. The total accumulating quantities of La in each component of simulated aquatic ecosystem were a decreasing order of: sediment >honewort>snail>fish, and the sequence of bio-concentration facter was as follows: honewort>snail>fish.
2金鱼藻对La有较强的富集能力,主要通过枝叶表面吸附、吸收而富集;螺蛳对La也有一定的富集,并主要分布于肠、壳中,螺头中积累相对较少;草鱼对La的富集能力相对较弱,进入鱼体的La主要集中在鳃、内脏、鳞及头、骨中,肌肉中积累量较少;按质量计,稀土元素La在模拟水生态系统各部分中的积累量依次为:底泥>金鱼藻>螺蛳>草鱼;各水生生物对稀土La的生物富集因子依次为:金鱼藻>螺蛳>草鱼。

The activitys of Super Oxide Dismutase, peroxidase and Multiple Displacement Amplification of Ceratophyllum demersum L raised rapidly in the late of experiment, and the maximum value of MDA of Ceratophyllum demersum L in the eutrophic condition was 5 time higher than that in the medium nutritional condition, implied that Ceratophyllum demersum L has been stressed in the middle nutritional condition.
金鱼藻超氧歧化酶活性、过氧化物酶活性和丙二醛含量在试验后期上升速度加快,且富营养水平下金鱼藻MDA质量分数的最大值是中营养水平下最大值的5倍,表明在中营养水平下金鱼藻已经受到明显胁迫,而在富营养水平下受到胁迫更为显著。

The results showed that during the 45 days experimental time the fresh weigh of Myriophyllum spicatum L, Hydrilla verticillata L and Cerato-phyllum demersum L were 0.92 g, 0.27 g, 1.11 g and 0.56 g, 0.41 g, 0.87 g in medium nutritional condition TN 1.86 mgL^(-1; TP0.087 mgL^(-1) and eutrophic condition TN 2.47 mgL^(-1; TP0.16 mgL^(-1), respectively. The largest single plant biomass of Myrio-phyllum spicatum L and Ceratophyllum demersum L in in middle nutritional condition were over 39% and 22% higher than those in eutrophicated condition, but that of Hydrilla verticillata L was less than 51%, which shown that Myriophyllum spicatum L and Ceratophyllum demersum L grow better than Hydrilla verticillata L in middle nutritional condition.
研究结果表明,在45 d的培养过程中,狐尾藻、轮叶黑藻和金鱼藻在中营养TN1.86 mgL^(-1; TP0.087 mgL^(-1)和富营养TN2.47 mgL^(-1; TP0.16 mgL^(-1)水平下的单株最大生物量分别是0.92、0.27、1.11、0.56、0.41和0.87 g,狐尾藻和金鱼藻在中营养水平下单株最大生物量分别较富营养水平下高出39%和22%,而黑藻在中营养水平下单株最大生物量较富营养水平下低了51%,表明狐尾藻和金鱼藻在中营养水平下的生长较黑藻好。

As the results show: The two submerged macrophytes can also adapt to the polluted water. Under the condition of high nitrogen in the sediment, they can remove the nitrogen effectively, and the removal effect of Ceratophyllum demersum L.is better than Hydrilla verticillata Royle. Hydrilla verticillata Royle activates the TP in the sediment more effectively than Ceratophyllum demersum L.. The submerged macrophytes can intensify the removal effect of turbidity. But the CODMn removal effect of submerged macrophytes are not obvious.
结果表明:生长晚期的黑藻和金鱼藻仍可适应污染河水;在底泥含氮量较高的情况下,生长晚期的沉水植物对氮素具有明显的去除效果,且金鱼藻的脱氮能力高于黑藻;黑藻对底泥中TP的活化能力高于金鱼藻;沉水植物可以强化浊度的净化效果;沉水植物生长晚期对CODMn的去除效果不高。
