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。
