Thesis Abstract

Abstract
Microplastic pollution has become a significant environmental concern globally, with freshwater ecosystems facing increasing contamination. This thesis presents the findings of a comprehensive study that assessed microplastic pollution in a local river, focusing on its sources, distribution, and potential impacts. Through a case study approach, the research aimed to provide valuable insights into the extent of microplastic contamination in the freshwater ecosystem and its implications for aquatic life and human health. Chapter 1 introduces the research by providing background information on the growing issue of microplastic pollution in freshwater systems. The problem statement highlights the need for a detailed investigation into the sources and distribution of microplastics in the selected local river. The research objectives are outlined to guide the study, emphasizing the importance of understanding the scope and limitations of the research. The significance of the study is underscored, along with the structure of the thesis and key definitions of terms related to microplastic pollution. Chapter 2 presents a comprehensive literature review that explores existing research on microplastic pollution in freshwater ecosystems. The review covers ten essential aspects, including the sources of microplastics, their distribution patterns, the impacts on aquatic organisms, and the potential risks to human health. By synthesizing previous studies, this chapter provides a solid foundation for understanding the current state of knowledge on microplastic pollution in freshwater environments. Chapter 3 details the research methodology employed in the study, outlining the steps taken to collect and analyze samples from the local river. The methodology section includes information on sample collection techniques, laboratory analysis methods, data interpretation procedures, and quality control measures. By following a systematic approach, the research ensures the reliability and accuracy of the findings obtained during the study. In Chapter 4, the thesis presents a comprehensive discussion of the research findings, focusing on the identification of microplastic sources, types, and concentrations in the local river. The chapter examines the spatial distribution of microplastics along the river course and assesses the potential ecological and human health risks associated with microplastic contamination. By analyzing the data collected, the study offers insights into the extent of microplastic pollution in the freshwater ecosystem and its implications for environmental sustainability. Chapter 5 concludes the thesis by summarizing the key findings, discussing their implications for future research and policy development. The conclusion reflects on the significance of the study in addressing the challenges posed by microplastic pollution in freshwater ecosystems and highlights the importance of sustainable management practices to mitigate this environmental threat. Overall, this thesis contributes to the growing body of knowledge on microplastic pollution and underscores the need for coordinated efforts to safeguard the health of freshwater ecosystems and biodiversity. In conclusion, the assessment of microplastic pollution in freshwater ecosystems, through the case study of a local river, provides valuable insights into the sources, distribution, and impacts of microplastics in aquatic environments. By addressing the research objectives and following a systematic methodology, this study contributes to a better understanding of the challenges posed by microplastic contamination and offers recommendations for future research and management strategies.
