Bachelor of Environmental Science and Management Student name Le Thi Huong Mai Student ID DTN1453060057 Thesis Title Monitoring the eutrophication of freshwaters Supervisor(s) Prof Dr Chihpin Huang- National Chiao Tung University, Taiwan Dr Do Xuan Luan- Thai Nguyen University of Agriculture and Forestry, Vietnam Supervisor’s signature Abstract: The eutrophication has emerged as a major concern in developing countries The present study sought to assess eutrophication and manage water quality in two research regions in Taiwan Besides, also evaluating the effects of installation solar panels in these places The study was designed as a collecting the water quality parameters: Chlorophyll-α (Chl- α), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), Ammonia Nitrogen (NH3-N) and transparency (SD) calculate and compare water quality through the River Pollution Index From calculations and analysis, there has been no eutrophication phenomenon affecting the quality of the water as well as the harmful effects of solar panels on the water that are installed in the reservoir Although most of the parameters indicate that water in the two study areas meets the criteria, further research is required to detect and handle promptly when signs of impact from eutrophication or solar panels occur, especially in the water used for irrigation i

ACKNOWLEDGEMENT Firstly, I would like to thanks to the cooperation between Thai Nguyen University of Agriculture and Forestry and National Chiao Tung University for giving me a precious chance to my research in wonderful country like Taiwan It brings me abundant honor to work and submit my thesis for graduation I really want to show my deeply grateful to Prof Dr Chihpin Huang for his generous and useful suggestions during the planning and development of my research work His pleasure to give his time so valuable to help me finished my internship in Taiwan I sincerely thanks to Dr Do Xuan Luan for his conscientious contribution, enthusiastic attitude and precious critiques of this research work and after I arrived to Taiwan, helping me to understand how to complete proposal and gave me thesis structure I am also thankful to Ms Hsiao-Fen and Mr Ngo Dinh Ngoc Giao for teaching me various techniques and methods used in water analysis field They were very helpful in providing me constructive feedback and suggestions on my project and helping me to successful complete several of my experiments and report Without them help and devotion, I afraid that I would not able to catch this stage I feel really lucky to be a part in Prof Dr Chihpin Huang’s lab Thanks to all the members in Professor Huang’s laboratory who willing give me a hand when I work in there I also show deep gratitude to my family for giving me emotional, encouragement and physical and financial support At last, I would like to thank all those other persons who supported me in finishing this report Due to my lack of knowledge, the mistake is inevitable, I am so thankful if I obtain the comments and opinions from teachers and others to contribute my report Sincerely, Le Thi Huong Mai iii download by :
