| 1 | The effects of K^+ growth conditions on the accumulation of cesium by the bacterium Thermus sp. TibetanG6显示文摘The accumulation of cesium by the bacterium Thermus sp. TibetanG6 was examined under different K+ growth conditions. The effects of external pH and Na+ on the accumulation of ce-sium were also studied, and the mechanism involved was discussed. K+ regimes played an important role in the accumulation of cesium by the strain TibetanG6. The quantity of cesium accumulated (24 h) was much higher in K+-deficient regime than that in K+-sufficient regime. The pH and Na+ had different effects on the accumulation of cesium in the two K+ regimes. IR spectra analyses indicated that the biosorption is a process of homeostasis with cesium initially accumulated on the cell wall. | WANG Hailei1,2,3, KONG Fanjing1,2,3 & ZHENG Mianping1,2,3 1.

| 2 | Cesium accumulation by bacterium Thermus sp. TibetanG7:hints for biomineralization of cesium-bearing geyserite in hot springs in Tibet,China显示文摘The bacterium Thermus sp. TibetanG7, isolated from hot springs in Tibet, China, was examined for the ability to accumulate cesium from solutions. Environmental conditions were simulated and the effects of pH, K+, Na+ and K+-regimes were then studied to determine the possible role of the bacterium in the formation of cesium-bearing geyserite around these hot springs. In despite of the inhibition of K+ and Na+, the bacterium Thermus sp. TibetanG7 revealed noticeable accumulation of cesium from solutions, with maximum accumulations of 53.49 and 40.41 μmol Cesium/g cell dry weight in Na+ and K+ inhibition experiments, respectively. The accumulation of cesium by this microorganism is rapid, with 40%―50% accumulated within the first 5 min. K+-deficient cells showed a much higher capacity of cesium accu- mulation compared with K+-sufficient cells. It is evident that the bacteria within the genus thermus play a significant role in the cesium assembly. The formation of cesium-bearing geyserite is also considered. | WANG HaiLei1,2,3, ZHENG MianPing1,2,3 & HUANG XiaoXing4 1 Institute of Mineral Resources, Chinese Academy of Geological Sciences (CAGS), Beijing 100037, China 2 R&D Center for Saline Lake and Epithermal Deposits, CAGS, Beijing 100037, China 3 Open Laboratory of Saline Lake Resourses and Environment, CAGS, Beijing 100037, China 4 Laboratory of Microbial Resources, Institute of Microbiology, Chinese Academy of Sciences, Beijing 100081, China | 2007 | Chinese Science Bulletin2007，52，19： | 2 |

| 8 | SIMULATION OF POLLUTANTS IN RIVER SYSTEMS USING FINITE DIFFERENCE METHOD显示文摘This paper using finite difference scheme for the numerical solution of advection-dispersion equation develops a one-dimensional water quality model. The model algorithm has some modification over other steady state models including QUAL2E, which have been used steady state implementation of implicit backward-difference numerical scheme. The computer program in the developed model contains a special unsteady state implementation of four point implicit upwind numerical schemes using double sweep method. The superiority of this method in the modeling procedure results the simulation efficacy under simplified conditions of effluent discharge from point and non-point sources. The model is helpful for eye view assessment of degree of interaction between model variables for strategic planning purposes. The model has been applied for the water quality simulation of the Hanjiang River basin using flow computation model. Model simulation results have shown the pollutants prediction, dispersion and impact on the existing water quality. Model test shows the model validity comparing with other sophisticated models. Sensitivity analysis was performed to overview the most sensitive parameters followed by calibration and verification process. | ZAHEER Iqbal1 and CUI Guang Bai2 1 Ph D candidate, College of Water Resources and Environment, Hohai University, Nanjing, China E-mail: zaheeriqbal@hotmail.com 2 Prof. College of Water Resources and Environment, Hohai University, Nanjing, China | 2002 | International Journal of Sediment Research2002，17，2： | 0 |
| 9 | Compensation for Land Loss in Reservoir Resettlement: A Case Study of The Three Gorges Project, China显示文摘This paper studies current policies in compensation for land lost due to construction of the Three Gorges project (TGP), China. In the case study of Kaixian County, the value of land in the peri-urban areas is underestimated. Some losses in land are tangible and thus measurable, but some losses are intangible and thus immeasurable. The land available in the resettlement areas is scarce and rarely of equivalent quality. This study suggests that the loss of agricultural land be compensated with alternative land and/or non-land-based livelihood strategies, including part compensation in monetary terms and preferential policies. | D Wang Yi-qian, Tan YanCollege of Resources and Environment, Lanzhou University, Lanzhou 730000, Gansu,China West China Development Institute, Sichuan University, Chengdu 610065, Sichuan, China Department of Geographical and Environmental Studies, The University of Adelaide, South Australia 5005.

| 10 | Prospects for Future Application of Fugacity Model to Fate Studying of POPs in China显示文摘POPs can stay long enough to diffuse and transfer sufficiently in the environment. Researches indicate that it's inadequate to study POPs' fate and environmental behavior, in order to get comprehensive knowledge of the POPs'fate and transfer processes in an area, experiment should be combined with model simulation. Recently multimedia models have become the primary choice in simulating organic pollutant's fate and assessing exposure risk to ecosystem for they can nearly represent the real environment. Among all models,with simple structure, less required parameters, fugacity model has been an efficient tool used widely on simulating the fate and transport of POPs and put into practice in many countries and areas successfully. On the basis of achievements in scientific research, this paper will emphatically take up the following three questions one by one that consist of fugacity model's principle, pivotal questions and application prospects in china. | D Li Yong-fu, Cao Hong-yingInstitute of Mountain Hazards and Environment, Chinese Academy of Sciences, Chengdu 610041, Sichuan, China Department of Geography, Beijing University, Beijing 610041, China | 2003 | Wuhan University Journal of Natural Sciences2003，8，03B： | 0 |
| 11 | MICROALGAE CULTIVATION IN A TUBULAR BIOREACTOR AND UTILIZATION OF THEIR CELLS显示文摘In this study on the possiblities of microalgae technology as an option for CO2 mitiga-tion, many microalgae were isolated from seawater. Some species of the isolates, Chlamydomonas sp.strain YA-SH-1, which accumulates starch in cells under light and ferment ethanol in dark and anaerobiccondition, was grown outdoors by using 50-L tubular bioreactors in batch cultivation and harvested. Usingthese cells, the performance of ethanol production was examined quantitatively in a 0.5-L scale fermen-tor. Another species, Tetraselmis sp. strain Tt-1, was cultivated in a semi-batch manner by a similar typeof tubular bioreactor indoors and examined for its utilization. Tests showed these cells could be used aspartial substitute for wood and kenaf pulp for processing into paper. With the idea of making microalgaeproduce cellulose by genetic engineering in their minds, the authors studied the structure of bacterial cel-lulose synthase genes and the low temperature-induced, reversible flocculation in a thermophilic bluegreen alga (Cyanobacterium), Synechocystis vulcanus in order to examine the feasibility of using thesegenes as gene source and the cynanobacterium as host. | Koyu Hon-nami Shunji Kunito(Energy and Environment R&D Center, Tokyo Electric Power Co. 4-1 Egasaki-cho, Tsurumi - ku, Yokohama 230, Japan)(E - mail: T0707125 @ pmail. tepco. co.jp) | 1998 | Chinese Journal of Oceanology and Limnology1998，16，S1： | 0 |
