Thesis Abstract

Abstract
Microplastics have emerged as a significant environmental concern due to their widespread presence and potential adverse effects on aquatic ecosystems. This thesis investigates the impact of microplastics on freshwater ecosystems, focusing on their distribution, accumulation, and potential consequences for aquatic organisms and ecosystem health. The study employs a combination of field surveys, laboratory experiments, and data analysis to assess the extent of microplastic pollution in freshwater environments and its ecological implications. Chapter One provides the foundation for the research by introducing the topic of microplastics in freshwater ecosystems, presenting the background of the study, defining the problem statement, outlining the objectives, discussing the limitations and scope of the study, highlighting the significance of the research, and presenting the structure of the thesis. Chapter Two consists of a comprehensive literature review that synthesizes existing knowledge on microplastic pollution in freshwater ecosystems. The review covers topics such as sources of microplastics, distribution patterns, interactions with biota, and potential ecological impacts. The chapter also examines current methodologies for microplastic analysis and monitoring in freshwater environments. In Chapter Three, the research methodology is detailed, including the sampling design, field and laboratory procedures, data collection methods, and statistical analyses employed in the study. The chapter outlines the steps taken to quantify microplastic concentrations, assess their characteristics, and evaluate their effects on freshwater organisms. Chapter Four presents the findings of the study, analyzing the distribution of microplastics in different freshwater habitats, identifying key sources of contamination, and evaluating the impacts on aquatic biota. The chapter discusses the implications of the results for ecosystem health and provides insights into potential mitigation strategies to reduce microplastic pollution in freshwater environments. Chapter Five concludes the thesis by summarizing the key findings, discussing their significance in the context of current environmental challenges, and proposing recommendations for future research and management practices. The study underscores the urgent need for effective measures to address microplastic pollution in freshwater ecosystems and highlights the importance of interdisciplinary approaches to safeguarding aquatic environments and biodiversity. In conclusion, this thesis contributes to the growing body of knowledge on microplastic pollution in freshwater ecosystems and underscores the importance of addressing this environmental issue to ensure the long-term sustainability of aquatic habitats and the organisms that depend on them. The findings provide valuable insights for policymakers, researchers, and stakeholders working to mitigate the impacts of microplastics on freshwater ecosystems and protect global water resources.
