In both Pacific oyster and Zhikong scallop, gonad of triploid animal was observed to development in the developing seasons. While during the gonadial developmental stage since 3 to 6 year-old, gonads of all triploid Pacific abalones fail to develop. Whether there is relation between a-TSP and gonadial development is to be studied.

皱纹盘鲍的三倍体个体性腺基本不发育，而长牡蛎和栉孔扇贝的三倍体虽然性腺发育不良，但可产生成熟的配子并可育，因此a-TSP与鲍的性腺发育抑制可能有关，但尚有待证实。

The results indicated that (1) the 147Pm, 141Ce and 147Nd had strong adsorptivity in soil, so they were hard to transfer and easily accumulated in soil or sediment;(2) all the organisms (5 aquaties and 4 eatable plants) tested showed apparent 147Pm concentrating capabilities;(3)the residues of 147Pm, 141Ce and 147Nd were unevenly distributed in the animal's viscera and tissues, higher residues were found in bone, marrow, eye, brain, heart, adipose and testis, showing selective accumulation;(4) with intraperitioneal dosing of Nd or Ce 200mg ·kg -1 apparent inhibition to gonadial hormone secretion in mice was found and with 200 and 800mg·-1 of Ce added in feed, the malformation rate of spematozoon showed higher.

综合研究结果表明： 14 7Pm、14 1Ce和14 7Nd在土壤中具有强的吸附性，而且难以迁移，易于在土壤和底泥中积累；( 2 )供试的 5种水生生物、4种陆生食用植物对14 7Pm均具有明显的富集性；( 3) 14 7Pm、14 1Ce、14 7Nd在动物体内脏器和组织间呈不均匀分布，在骨骼、骨髓、眼、大脑、心脏、脂肪和睾丸中残留量较高，表现了明显的选择性蓄积；( 4 )一次性腹腔注射2 0 0mg·kg-1的Ce和Nd对小鼠性腺激素的分泌有明显的抑制作用，以 2 0 0和80 0mg·-1的Ce随饲料摄入对雄性小鼠精子畸形率明显升高。
