The rate at which the environment in China deteriorates is alarming. It is even feared that the entire Chinese civilization will terminate if this deterioration continues uncurbed. However, equally astounding is the reluctance on the part of the general public to take concrete actions against this dire possibility. What is encouraging in the face of this bleak picture is that a generation of responsible young people, including myself, is making relentless efforts for the rescue of this much abused environment. In my undergraduate program at Hebei Engineering University, Tianjin, and graduate program at Beijing Technology and Business University, I have chosen to major in Environmental Engineering. Between those two programs, I had 2-year work experience (1997 1999) at Beijing Yanshan Petrochemical Co., Ltd where I was responsible for environmental monitoring and pollution control. Nevertheless, it seems that environmental protection is such an immense task that no matter what efforts we make, they never suffice. The backward condition of China in the field of environmental protection makes it necessary for us to learn from the experiences of the advanced countries. On the other hand, with the increasing awareness of the importance of environmental protection, environmental control is developing into a new industry with a promising prospect. To pursue a successful personal career in this field has become my aspiration. Under such circumstances, I file this personal statement to your esteemed university under the hope of seeking more advanced trainings in the field of environmental engineering.In the course of nearly a decades education and research, I have made some tentative achievements in the field of environmental engineering. My thesis, entitled Design for the Disposal Plant of the Sewage Emitted by the Printing and Dyeing Mills of ShengZe Township in Jiangsu Province, focused on the treatment of the waste water emitted by the local printing and dyeing mills by means of anaerobic-aerobic method, which was a quite advanced approach at that time. I collaborated closely with the students in my project team to formulate the design parameters, the processing procedures and other steps. In our design, 70% percent COD in the sewage could be eliminated anaerobically and 95% percent BOD could be eliminated aerobically. So far, the plant has been put into use, playing a major role in the local environmental protection. My thesis, which was based on this project, was rated “Class A”, an achievement which only 3% students in the entire university could attain.Another similar project in which I participated was the Sewage Disposal Workshop of Xian Brewery. In this project, the design of the anaerobic tank was the key. I conducted detailed analysis of the design parameters and the structure of the anaerobic reactor. After the debugging, it could eliminate 98% COD, an achievement up to the advanced domestic level. In the project, the ingenious design of the 3-phase separator in the anaerobic pond received national patent.After graduation, I found employment with Beijing Yanshan Petrochemical Co., Ltd where I was in charge of the operation of production facilities and the monitoring and the controlling of detrimental materials in the emitted sewage. The best part of this 2-year work experience was that it made me realize that environmental science, including pollution control, is a comprehensive science subsuming many individual subjects. To be better qualified, I had to acquire a more systematic education. Therefore, I embarked on a Maters program in which I studied the most recent theories in the field of sewage treatment, atmospheric pollution control, environmental monitoring. I focused on comprehensive atmospheric evaluation, environmental chemistry, and environmental system analysis. In order to strengthen myself, I paid special attention to the study in biology, computer skills, and the relevant mathematical methods.During my Masters program, I have been most interested in the monitoring of water pollutants by using biosensor. My thesis - The Study of Amperometric Tyrosinase-Membrane Electrode Modified with Maltodextrin for Detection of Phenols is such an instance of applying the biosensor to environmental monitoring. It was designed to maximize response electric current and to reduce the lower limit of testing by selecting appropriate activators to enhance the activity of the enzyme. I developed the method of using the membrane as a vehicle to fix tyrosinase. The amperometric tyrosinase-membrane electrode I developed could detect phenols with greater precision and speed (20 times quicker than the conventional 4-azyl antipyrine colorimetric method). In order to turn this research finding into a useful product and to reduce the cost of making electrode, I researched on biological fixation and improved our design of instruments. Currently we are cooperating with a major domestic manufacturer in analytical instruments to turn out products of this kind. The Fluid Injection System (FIS) we designed can realize online monitoring and the sample machine is expected to be produced within the end of this year. The entire project has been rated by the State Environmental Protection Commission as “demonstrating leading technology by both international and domestic standards.” My thesis, based on the research findings of this project, was again rated “Class A”.In connection with this research project, I wrote a research paper entitled Research of Tyrosinase Biosensor for Detection of Phenols, which has been published in the Journal of Beijing Technology and Business University in January 2002. The two other papers to be published are The Study of a Tyrosinase Membrane Electrode Modified with Maltodextrin for Detection of Phenols and Using a New-Style UASB Reaction to Treat Beer Wastewater. Those important research achievements can fully testify to my research potential.By accumulating abundant experimental skills and experience, I have served as an important research assistant to my supervisor. I have assisted my supervisor to have done the appraisal for the project “Study of Non-polluting and Low-Cost Tyrosinase Electrode for Detection of Phenols”. In addition, by carrying out a considerable amount of independent research work, I have helped him to have succeeded in applying for the project The Detection of Coli.e in Water by Means of Biosensor. Finally, I have attended “Engineering Science and Technology Forum Problems and Strategies for Urban Environment” and a number of other academic conferences. Those activities have enabled me to keep informed of the latest developments in the field of environmental engineering.In conclusion, I have made more achievements than the majority of my peers. I attribute this fact to my serious commitment to environmental science and to my diligence. My scholastic ranking on entering the university was below average. But with persistent efforts, I managed to attain a top ranking in my class, achieving highest scores in the exams of seven core courses including Environmental Micro-Biology. In my undergraduate program, I was awarded the China Petrochemical Co., Scholarship. My scores for the entrance examination of the Masters program were also the highest and I succeeded in maintaining this top-level performance throughout the program. For this, I received Scholarship for the Student of Excellence. I believe that in my future degree program, I will continue to achieve academic excellence.“The earth does not belong to the human beings but the human beings belong to the earth.” As part of global environmental protection enterprise, Chinas environmental efforts call for highly qualified researchers and administrators in environmental protection. I have decided to apply for a Ph. D program in either of the following fields: Monitoring and Control of Industrial Wastewater by Through Technical Measures/or Environmental System Analysis and Management. I will make full use of the education by strong faculty at your esteemed university, advanced research facilities and an inspiring academic climate. While continuing to deepen my theoretical knowledge, I will endeavor to acquire latest information on environmental science and technology. In addition, I will continue to improve my experimental skills, including the skills of operating new instruments. All those efforts are designed for just one purpose to develop myself into a leading environmental specialist who can make important contributions to the countrys fledgling cause of environmental engineering.由留学陶瓷网修改的部分:1. 加了一个更吸引人的开头.你不需要简单复述简历上的东西,比如I major in XXX in XXXuniversity.2. 去掉了高中就感兴趣.,原文并没有说明为什么,改文第一段已说明.3. 去掉了GPA,这个GPA已经不错了，而且在简历里也有。个人觉得没有必要解释什么。如果想强调GPA的高，还缺少证据。其实，PS最好是一个研究型的，完全没有必要把GPA, IBT, GRE等写进PS.4. 对接下去两段，对研究不大懂。稍微调整了一下语句，基本没有改。5. 对社会活动什么的，个人觉得在简历里出现就可以了。6. 结尾，由于是交换生，没有必要说明为什么要选那个学校，交换嘛，美的选。7. 总体是更加简洁，更加“研究型”“学术型”U 修改后PS：Not far from my university, Lake XXX, which has been famous for thousands of years as the most beautiful lake in China, is facing the problem of eutrophication. A hundred kilometres north at the boarder of XXX Province, Lake XXX, the XXX largest in China, is experiencing the outbreak of blue algae. These are just two scenes that depict the deteriorated clash between economic and environmental concerns I witnessed over the last decade in China, which attracted me to the environmental engineering program in China University and attracts me to the exchange program in environmental microbiology in USA University.In China University, Ive built a strong background in biological science which helps me to understand the sewage biological treatment technology and biodegradation. In the Biochemistry course, I learned about the metabolism of sugar, protein, and fat acid, especially the ways of sugar degradation which are known as tricarboxylic acid circle, Embden-Meyerhof-Parnas pathway, and hexose biphosphate glycolysis. In the Environmental Biology course, I learned about the microbiology degradation and bioremediation of certain organic pollutants. I also understood the biogeochemical cycle which plays an important role in learing management and use of water resource.Extensive experimental and practical skills are also valuable assets I obtained during my undergraduate study. In an open microbiology experiment design project, my group designed an experiment on luminescent bacteria toxicity. We tested toxicity of landfill leachate of the whole processing flow in regulating tank and sedimentation tank. In the 4th student research training program of ChinaUniversity University, I worked on a project in the determination of seasonal variation of detection of disinfection by-products in drinking water. During the training, we have applied headspace capillary gas chromatography to determine the trace DBPs(Disinfection By-products), especially the THMs. For the research of the variation of DBPs through time and space scales, we determined the sampling interval and regional distribution. In addition, we detected the DBPs in local beverages. The research training improved my expertise in experiment designing, literature reviewing and device operating. During my intern in the Environmental Monitoring Station of Hangzhou City. I used XXX技术 to XXX目的. This experience enhanced my comprehension of my major and improved my team-work ability and communication skills. With my solid academic background in environmental engineering, I am ready to take a further step to enrol in graduate study. I am most interested in the field of biodegradation of contaminants in water and soils. In USAUniversity, I would be able to take courses that improve my expertise in this field, such as Water and Waste Treatment Plant Design. I would also be able to involve in advanced research carried out in USAUniversity. The graduate study in USAUniversity would improve my ability in practical problem solving and would be a key step in my professional career.Two scenes stand out in my mind from my visit to Brazils Wetland: Forests burning before seed planting and trees as hedgerows. Before the planting season, I could see the leafless remnants of burnt trees still standing. The burning of pristine forests destroys both the habitats and countless species which depend on and thrive in these habitats. The few remaining bare, scarred trees silently convey the cost to our natural resources of pursuing our economic interests. Some forests are preserved by government edict issued in response to international pressure. But most of this preservation occurs alongside major roads not to protect the ecosystem, but to prevent disturbance to ranches and farms along the highways. The clash between economic and environmental concerns that I witnessed in Brazil fascinates me and attracts me to the Environmental Studies Program.Two courses in my geography department increased my interest in the connection between the environment and economics: Conservation of Underdeveloped Countries and Environmental Impact Analysis. In the former, we studied the problems of natural resource management in developing countries. The balance is always tilted toward economics growth at the expense of environmental preservation. For example, because the Pantanal Wetland could become a highly productive agricultural system once its drained, it is drained regardless of the destruction that drainage causes to the ecosystem. Only portions of the wetland are preserved for tourist purposes.The other course that piqued my interest is an interdisciplinary course called Environmental Impact Analysis in which we, as a group, created matrix and flow diagrams discussing the economic and environmental impact of logging and preservation of old growth forests. I was able to use tools that I acquired in my economics and environmental studies classes. In general, logging creates economic benefits at the local level. It increases employment in the timber industry and subsequently in related non-timber industries; it also benefits local government. Yet, it has great deleterious environmental effects: soil erosion, watershed destruction, and a decrease in specie diversity due to loss of habitat. The logging industry represents the classic clash between economic and environmental interests.I also took two sequential classes in the economics department that are related to Resource Management Theories of Growth & Development and Policies for Economic Development. Because the courses were taught by a professor who is concerned chiefly with economic growth, I learned the standard economic rationalizations for development unrestrained by environmental concerns.In addition to my interest in resource management policies, I have a specific interest in Geographical Information System (GIS), a powerful tool for natural resource management. After taking several related classes in GIS, I began interning for the National Park Service (NPS). After I learn how to use ARC/INFO, a leading GIS package, I will assist the NPS in constructing projects. Some of my duties include spatial and non-spatial data analysis, digitizing themes such as fire locations, vegetation, wildlife habitats, etc., and tabular and graphical presentation of results. I hope to use the tools I acquire during this internship in my continuing study of our environment.I would like to study the social and economic factors that influence environmental policy formation. For example, because people worry more about pollution than endangered species, laws and regulations concerning environmental pollution are more numerous and stricter than for bio-diversity. Within the School of Environmental Studies, I have a particular interest in the emphasis: Economics, Policy, and Management. This emphasis deals with how economic factors can create negative externalities, such as pollution, and need to be regulated. This emphasis also tries to consider non-economic values, such as aesthetic pleasure and specie diversity. It also discusses tools like GIS and system analysis that apply to environmental management. Because of my interest in GIS, economics, and environmental studies, this emphasis suits me perfectly. Furthermore, the interdisciplinary approach of the School of Environmental Studies attracts me since it combines social sciences strengths with a knowledge of the natural sciences necessary to protect and preserve the environment. After completing my masters program, I would like to continue my education and obtain a Ph.D. in natural resource management. This degree would enable me to combine a teaching career with advising business and government on natural resource management issues. Teaching college students is more than a one-way channel; I would also learn from their questions like my professors have from mine. In advising business and government, I can help them strike a balance between economic and environmental concerns. GIS will be a useful tool in helping me give them crucial information.I have enjoyed an interdisciplinary approach in my environmental studies major and become fascinated by the clash between social interests, especially economics, and environmental needs. I pursued an additional major in economics to better understand this conflict. Furthermore, my work for the NPS will train me in the latest techniques in natural resource management. I would like to continue exploring this clash and resource management in the School of Environmental Studies. Ultimately, I would like to teach and work in natural resource management. Ideally, I would like to find ways for allowing development while preventing the burning of beautiful and valuable eco-systems like the Pantanal Wetland.Nowadays, Environmental Engineering plays a vital role in the world as the environment is being put under c
