Main purification role is played by artificial medium and aquatic macrophyte in pollutants removal, but the Corbicula fluminea introduced to food chain of combined floating bed enhances the purification effect through the ways as follows: improving the resolvability, ammonification and biodegradability of particulate organic matters, meliorating the substrate supply condition for absorption of plant and degradation of microorganism attached on artificial medium, hastening the growth and activity of microorganism.

Physiological Responses of Hybrid Striped Bass to Aqueous Copper copper is an abundant trace metal, and although essential at low levels, it is also potentially toxic to aquatic organisms.Mechanisms of toxicity and consequences of exposure vary depending on ionoregulatory status(acclimated to freshwater or salt water).The goal of this research was to examine the responses of hybrid striped bass(Morone chrysopsXMorone saxatilis)exposed to Cu in freshwater and 15g/L salt water.In freshwater,a general dose-and time-dependent pattern of increasing Cu accumulation in gill tissue was evident in fish exposed to aqueous Cu(220 and 447 mg/L)for up to 96 hours.The 96-horu acute median lethal concentration for freshwater-acclimated hybrid striped bass exposed to Cu was 94mg/L(confidence interval=62 to 144mg/L).

生理反应到水的混合条纹鲈鱼铜是一个丰富的微量金属，虽然至关重要，它是在较低的水平也可能对水生生物有毒毒性机制及其后果的曝光取决于ionoregulatory状态，本研究的主要目的是为了检查的反应chrysopsXMorone混合条纹鲈鱼暴露于铜在淡水和15 / L盐水在淡水，一般dose-and时变模式日益增长的铜积累鱼鳃组织显然暴露于含水的铜(220和447毫克/升)长达96小时96-horu致命的平均浓度为freshwater-acclimated急性混合条纹鲈鱼暴露于铜被94mg / L(=置信区间来144mg / L)62 osmolatity、钠浓度降低。

Eliminating or degrading phenolic contaminants in water was involved not only with the bioplastic and propagation of hydrephily biology but also with drinking safety of mankind and terraneous animals.

鉴于清除或降解水中的酚类污染物，不仅涉及水生生物及陆生植物的生长繁殖，更涉及到人类及陆生动物的食品饮水安全，因此，研究含酚废水的高效处理技术，对保护环境具有极为重要的意义。

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。

The damage in gill under sublethal monocrotophos exposure included hypertrophy and edema,and thus,the lamellar epithelium became thick and lifting,and the lamellae were bulbing or fusing.

鱼类在水生生态系统中占有极其重要的地位，也是水体中对有机磷农药较为敏感的一类生物，因此可用鱼类来研究和预测农药对水生生态系统的影响。

Influence factors and rules for adsorption and ion-exchange of ammonia nitrogen by zeolite were analyzed.
