Thesis Abstract

Abstract
Microplastic pollution in freshwater ecosystems has become a growing concern due to its potential impact on aquatic organisms and the environment. This thesis presents an in-depth investigation into the sources, distribution, and impact of microplastics on aquatic organisms in freshwater systems. The study aims to provide valuable insights into the extent of microplastic pollution, identify key sources of contamination, assess the distribution patterns of microplastics, and evaluate the potential effects on aquatic organisms. The research methodology involved a comprehensive literature review to establish the current knowledge on microplastic pollution in freshwater systems. Field surveys and sampling were conducted in various freshwater bodies to collect water and sediment samples for microplastic analysis. The samples were processed using established protocols to quantify and characterize the microplastic particles present. Chapter 2 of the thesis provides a detailed review of the literature on microplastic pollution in freshwater ecosystems. It covers topics such as the sources of microplastics, distribution patterns, environmental fate, and the impacts on aquatic organisms. The review highlights the gaps in current knowledge and sets the stage for the empirical study conducted in this research. Chapter 3 outlines the research methodology employed in this study. It includes details on the sampling locations, sample collection methods, laboratory analysis techniques, and data interpretation procedures. The chapter also discusses the challenges and limitations encountered during the research process. Chapter 4 presents the findings of the study, including the quantification of microplastic particles in water and sediment samples, the identification of key sources of contamination, and the distribution patterns observed in the study areas. The chapter also discusses the potential impact of microplastics on aquatic organisms based on the results obtained. Chapter 5 offers a comprehensive conclusion and summary of the research findings. It discusses the implications of the study results for freshwater ecosystem management and highlights the significance of addressing microplastic pollution in these environments. Recommendations for future research and policy interventions are also provided. Overall, this thesis contributes to the understanding of microplastic pollution in freshwater ecosystems and underscores the urgent need for effective mitigation measures to safeguard aquatic organisms and ecosystem health. The findings presented in this study serve as a valuable resource for policymakers, environmental managers, researchers, and other stakeholders working towards addressing the challenges posed by microplastic pollution in freshwater environments.
