Thesis Abstract

Abstract
The presence of microplastics in freshwater ecosystems has become a growing environmental concern due to their potential adverse impacts on aquatic organisms and ecosystem health. This thesis aims to investigate the impact of microplastics on freshwater ecosystems, focusing on their distribution, accumulation, and effects on aquatic organisms. The study utilizes a combination of field sampling, laboratory experiments, and data analysis to assess the presence and impact of microplastics in freshwater environments. The introductory chapter provides a comprehensive overview of the research topic, including the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The literature review chapter critically examines existing studies on microplastics in freshwater ecosystems, covering topics such as sources of microplastics, transport mechanisms, ecological impacts, and mitigation strategies. The research methodology chapter outlines the study design, sampling techniques, laboratory analysis methods, and data interpretation approaches used in the study. Key contents include site selection criteria, sample collection protocols, microplastics extraction procedures, and statistical analysis methods. The chapter also discusses the ethical considerations and limitations of the study. The findings chapter presents the results of the field sampling and laboratory experiments, highlighting the distribution and abundance of microplastics in freshwater ecosystems, as well as their effects on aquatic organisms. The chapter includes detailed discussions on the types of microplastics detected, their spatial and temporal variability, and the potential ecological risks associated with their presence. The conclusion and summary chapter synthesizes the key findings of the study, discusses their implications for freshwater ecosystem health, and provides recommendations for future research and management strategies. The study contributes to the growing body of knowledge on microplastics in freshwater ecosystems and underscores the need for effective measures to mitigate their impacts on aquatic environments. Overall, this thesis provides valuable insights into the impact of microplastics on freshwater ecosystems, highlighting the importance of understanding and addressing this emerging environmental challenge. The findings of this study can inform policy decisions and conservation efforts aimed at protecting the health and integrity of freshwater ecosystems in the face of increasing microplastic pollution.
