Thesis Abstract

Abstract
Microplastic pollution in freshwater ecosystems is a growing environmental concern that poses significant risks to aquatic life and human health. This thesis presents a comprehensive assessment of microplastic pollution in freshwater environments, focusing on the sources, distribution, and impacts of microplastics. The study aims to provide valuable insights into the extent of contamination, identify key sources of microplastics, and evaluate their potential ecological and human health implications. Chapter One introduces the research, outlining the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and key definitions related to the study. The literature review in Chapter Two critically examines existing research on microplastic pollution in freshwater ecosystems, discussing key findings, methodologies, and gaps in knowledge. Chapter Three details the research methodology, including sampling techniques, sample analysis methods, data interpretation, and quality control measures. The chapter also describes the study area, sample collection sites, and the analytical tools used to quantify and characterize microplastic particles in the water column, sediments, and biota. In Chapter Four, the findings of the study are presented and discussed in detail. The results highlight the prevalence of microplastics in freshwater ecosystems, with a focus on the types, sizes, and concentrations of particles detected. The chapter also explores the spatial distribution of microplastics, their interactions with biota, and potential pathways for human exposure. Chapter Five concludes the thesis by summarizing the key findings, discussing their implications for environmental management and policy, and suggesting future research directions. The study underscores the urgent need for coordinated efforts to monitor and mitigate microplastic pollution in freshwater ecosystems, emphasizing the importance of stakeholder engagement, public awareness, and regulatory interventions. Overall, this thesis contributes valuable insights into the assessment of microplastic pollution in freshwater ecosystems, shedding light on the complex nature of this environmental issue and its far-reaching impacts on ecosystem health and human well-being. The findings of this study have important implications for sustainable resource management, conservation strategies, and the protection of freshwater biodiversity in the face of mounting plastic pollution threats.
